The system empowered manufacturing clients with cost visualization tied to improved production efficiency and reduced delivery lead times—delivering operational insight directly aligned with customer ROI. My core contribution was building the data infrastructure to estimate and visualize the progress of an entire work order—beyond just machine-level activity. This was a first-of-its-kind capability in the industry, offering live, in-progress visibility. Traditionally, leadership would only learn of a work order's status—whether early, late, or on schedule—once production was complete; this system provided real-time insight, enabling faster decisions and greater operational control. I played a central role in transforming MachineMetrics’ hardware software layer into a self-serviceable platform, reducing customer reliance on proprietary hardware. I built a software layer for the edge device that allowed clients to configure connectivity settings independently, eliminating the need for on-site visits from connectivity engineers. This enabled scalable machine onboarding (e.g., 300+ machines), improved transparency into edge-device data, and reduced deployment friction—particularly for smaller or distributed manufacturing teams. The initiative increased configurability, accelerated rollout timelines, and expanded the customer onboarding experience by 35%, broadening our addressable market. In a highly collaborative effort, I co-led, co-designed, and executed a third-party integrations platform that became a core part of MachineMetrics’ ecosystem strategy. This project was showcased at IMTS, North America’s largest manufacturing trade show, where it became a featured product and generated over 1,200 qualified leads—one of the company’s most successful campaigns to date. ### Full Stack Engineer I @ MachineMetrics Jan 2021 – Jan 2022 I was part of MachineMetrics’ core application (Growth) squad, responsible for maintaining and enhancing the web application that delivers machine performance insights to manufacturing clients. Our platform contextualized machine metrics to help customers reduce equipment downtime, increase profit margins, and optimize workflows—contributing directly to MachineMetrics’ 40% CARR growth and 110% Net Revenue Retention (NRR). I played a key role in addressing technical debt by expanding our efforts to resolve long-standing bugs. Over time, I reduced the backlog by 65%, maintaining a 95% non-recurrence rate. One critical issue I resolved involved the time context logic in the report builder—a heavily used feature. When users generated reports grouped by week, the bug produced output showing 6, 8, or even 9 days per week due to improper handling of time shifts. Another major issue I helped resolve was a memory overload on one of our core servers, where a new watcher process was unintentionally spawned on every triggering transaction, leading to excessive memory usage and ultimately systems failure. One of my most impactful feature contributions was the global regionalization of date and time across the application. I implemented a solution that respected both the user’s language and their company’s regional formatting preferences. Since date and time appeared in roughly 85% of the app, this significantly improved user experience—contributing to an estimated 30% boost in customer quality of life, especially for international users navigating diverse formats. ### Instructor @ Fullstack Academy Jan 2023 – Jan 2024 | New York, New York, United States As a lead instructor, I was responsible for delivering technical instruction to a cohort of 50 non-technical Amazon employees—ranging from fulfillment center associates to corporate staff—transitioning into software engineering. My focus was on building foundational development skills while maintaining engagement across a diverse learner population. The biggest challenge was managing the wide disparity in technical knowledge within the group, from individuals with no prior exposure to code to those with light technical familiarity. Through individualized support, strategic pacing, and curriculum scaffolding, I successfully guided the entire cohort toward a shared technical foundation. Despite the disparity in technical readiness, I helped my cohort achieve the lowest dropout rate (20%) among all comparable cohorts and drove a graduation rate of 87.5%, placing in the 90th percentile across similarly structured programs. These results reflect my commitment to accessible instruction, individualized support, and delivering consistently high learning outcomes in challenging, entry-level environments. ### Senior Fellow @ Fullstack Academy Jan 2021 – Jan 2021 | New York, New York, United States Promoted to 1 of 2 Senior Fellows based on recommendations from lead instructors. In addition to my prior mentorship responsibilities, I took on expanded leadership and technical support duties, including direct collaboration with the Curriculum Developer and mentorship of other Fellows and engineers. Notably, in coordination with the Curriculum Developer, I helped integrate AWS Cloud9 into the engineering curriculum. We had observed that one of the major obstacles in the development process stemmed from hardware limitations or environment configuration issues faced by engineers. This integration reduced friction from local hardware and configuration issues, and resolved approximately 90% of environment-related blockers and improved onboarding speed. I also collaborated with a Fellow to create updated content on React function components, hooks, and advanced patterns for replicating Redux logic—modernizing learning outcomes in line with industry practices, as the existing curriculum was still heavily based on class components—a legacy pattern that had been superseded by hooks in modern React development. As part of my leadership responsibilities, I served as a technical advisor to incoming Fellows, sharing effective strategies for mentoring engineers and creating engaging learning experiences. I directly mentored seven engineers through a mix of 1:1 and group sessions, often going beyond the scheduled curriculum to support their growth. These sessions gained popularity within the cohort and contributed to my team consistently ranking in the top 10% of performance throughout the program. ### Fellow @ Fullstack Academy Jan 2021 – Jan 2021 | New York, New York, United States Selected as 1 of 7 Fellows from a cohort of 54 to work closely with Fullstack Academy engineers and lead instructors. My responsibilities focused on mentoring engineers and supporting their practical development as Full Stack Engineers. In the first six weeks, I guided and trained a dedicated team of five engineers in full stack development concepts, system architecture, and engineering best practices. I covered topics—from DOM manipulation and framework design on the frontend to service interaction and API layering on the backend—while tying both ends into the broader software infrastructure. A key part of this role was adapting my teaching style to each engineer’s learning needs. I designed creative instructional approaches, including analogies and visual metaphors, to drive conceptual clarity and produce “aha” moments. In the second half of the program, I took on the role of Engineering Manager and led two separate project teams through the full software development lifecycle. During ideation, I provided structured critiques to shape feasible and impactful product concepts. During development, I implemented Agile practices with standups, sprint planning, and in-depth code reviews. My goal was not only to guide delivery but also to cultivate strong team dynamics and individual ownership over technical decision-making. ### Research Analyst @ IQ-G Partners Jan 2019 – Jan 2019 | Greater New York City Area At IQ-G Partners, I supported both the Private Equity and Hedge Fund arms of the firm. I conducted investment research and presented strategic recommendations for mid-cap opportunities in the $100–200 million range. For the Private Equity division, my research focused on Credit Tenant Lease (CTL) financing projects tied to state-owned enterprises in emerging markets including India, Peru, and Romania. In evaluating potential private equity investments, I assessed sovereign credit ratings, government debt obligations, and privatization plans to determine country-specific risks and market viability. I categorized my recommendations by region and investment opportunity and presented them to the firm’s Chairman. Several weeks later, a Wall Street Journal article echoed the key themes and investment outlook reflected in my research, further validating the strategic direction of my recommendations. For the Hedge Fund division, I prepared executive summaries profiling hedge fund managers under consideration for capital allocation. I evaluated key performance metrics—including annualized returns, Sharpe ratios, Sortino ratios, and maximum drawdowns—along with strategy types and target markets to inform the firm’s due diligence process. ### Real Estate Research Analyst @ Berko & Associates Jan 2018 – Jan 2018 | Greater New York City Area At Berko & Associates, my responsibilities were divided across identifying potential financing clients in the commercial real estate space, generating leads for a $150 million investment deal, and supervising a team of new interns. Sourcing for potential financing clients, I conducted in-depth research on commercial real estate firms by analyzing their business models, asset sizes, and geographic presence. Among my team, I achieved the highest callback success rate at 7%. Qualified leads were introduced to capital providers in the Israeli market, where financing costs, at that time, were 700 basis points lower than U.S. equivalents at the time. I had the opportunity to work directly with firm Partners on a $150 million real estate transaction. My work involved canvassing up-and-coming residential neighborhoods, establishing relationships with potential buyers and sellers, and preparing COMPS on canvassed assets. I canvassed four neighborhoods in total, including Sunset Park, Brooklyn and Belmont, Bronx, contributing localized market intelligence to support investment decisions. Due to my performance and reliability, I was given supervisory responsibilities over a team of five interns. I coordinated their research activities across financing and canvassing efforts, ensuring consistency in data quality and timely delivery of insights. ### Payment Support Associate @ Ascendus Jan 2016 – Jan 2017 | 80 Maiden Lane, New York, NY 10038 As a Payment Support Associate, I led the administrative arm of the payments team. I managed the end-to-end process of identifying and preparing 500+ write-off accounts for portfolio transfer to collection agencies, including compiling key documents such as Promissory Notes and Write-off Quotes. This initiative directly improved risk exposure and contributed to increased recovery rates, reinforcing my ability to design scalable workflows with long-term operational impact. I took ownership of developing and delivering internal back-office reports for senior leadership, including the COO. These reports addressed sensitive and time-critical issues such as bankruptcies, Proof of Claim filings, and payment documentation. Producing these deliverables required meticulous attention to data integrity, structured thinking under pressure, and the ability to communicate clearly with both operational and executive stakeholders. This role sharpened my ability to solve real-time problems within within complex, constraint-driven systems. I developed a disciplined approach to documentation, version control, and operational throughput—skills that now serve as a foundation for writing clean, maintainable code and operate effectively in fast-paced, detail-driven environments. ### Intake Intern @ Ascendus Jan 2016 – Jan 2016 | 80 Maiden Lane, Suite 903, New York, NY 10038 As an Intake Intern, I served as the first point of contact for clients, helping them navigate Ascendus’ financial products and initiate their financing journey. My responsibilities included addressing client inquiries, generating qualified leads, and processing loan applications. A significant portion of my role involved direct, high-volume communication with clients and prospects over the phone. These interactions required a strong grasp of Ascendus’ product suite, adaptability in tone and approach based on client temperament, and the ability to establish trust quickly. Ensuring client satisfaction—whether answering questions or nurturing early-stage leads—was a key personal objective that I consistently prioritized. Outside of client interactions, I processed an average of 6 loan applications per day using the EDGE software. This involved evaluating credit reports, assessing creditworthiness, and making risk-aware decisions to accelerate the funding process. My contributions supported operational efficiency and helped sustain a portfolio-wide delinquency rate under 5%, aligning directly with Ascendus’ mission to provide accessible capital to small business owners. ## Education ### Master of Science in Finance in Investments and Securities Zicklin School of Business ### Bachelor of Business Administration - BBA Baruch College ## Contact & Social - LinkedIn: https://linkedin.com/in/tun-oo-swe - GitHub: https://github.com/tunooswe --- Source: https://flows.cv/aaronshen JSON Resume: https://flows.cv/aaronshen/resume.json Last updated: 2026-03-23
