# Jakub Klapacz > Digital Plumber and Chief Git Wrangler Location: Bolingbrook, Illinois, United States Profile: https://flows.cv/jakub I'm a senior software engineer with a background in artificial intelligence and big data. I wish to work on data-driven systems with an uncompromising focus on performance (application-level as well as developer-experience). Having worked at a number of startups I feel very comfortable amidst the chaos of a high-growth startup; the insights I bring from witnessing what happens when a tech startup takes off can be very valuable in helping avoid expensive mistakes. I have created applications from the ground up, broken apart legacy monolithic systems into microservices, created and maintained CI/CD pipelines, mentored and onboarded team-members and served as the subject matter expert on a number of (legacy) on-premise systems... at my core I am a technologist who strongly believes in automating what can be automated and am comfortable in almost any technical context. My recent focus has turned towards working on tools which improve developer productivity and the developer experience and I am excited about the idea of utilizing AI/ML to improve the way developers can write code. ## Work Experience ### Staff Software Engineer @ Gordian Software Jan 2023 – Present | Bellevue, Washington, United States ### Senior Software Engineer @ Gordian Software Jan 2021 – Jan 2023 | Bellevue, Washington, United States Gordian Software is on a mission to redefine air travel by building the Operating System of Travel. We do this by layering intelligent software on top of existing systems to make every decision involved with booking a flight as easy as just pressing a button. Currently I am working on leading improvements in infrastructure and observability to improve stability and robustness to the core application platform. ### Senior Software Engineer @ Pindrop Jan 2020 – Jan 2021 | Atlanta, Georgia, United States Pindrop applies cutting edge artificial intelligence and machine learning techniques in order to bring security, identity, and trust to every voice interaction. Now a late-stage startup, when I joined the company was going through a period of exponential growth. In a relatively short period of time I had been exposed to many layers of the application stack and have gained significant experience in many aspects of software engineering. The needs of working at such a startup have exposed me to non-trivial experience in many software engineering topics including: data-engineering, cli development, library development, tooling improvements, analytics, distributed applications, ci/cd, build tooling, sql (database) optimizations, and much more. Highlights: * Architected and implemented a framework built on top of AWS Lambda and Terraform allowing for programmatic management of internal platforms [kubernetes, rds, terraform, aws lambda] * Worked with internal support team to design and implemented a process to automatically migrate customers into our cloud environment. * Created developer tooling to spin up full production environments using firecracker virtual machines enabling a deployment process which has decreased from ~10 minutes to ~30 seconds * Discovered significant cost saving opportunities by analyzing a complex build system and designing an alternative process to reduce development costs by over $100K yearly. [esbuild,snowpack,deno,node.js] * Implemented an alternate build system for a large production-critical react application using esbuild instead of webpack. Eliminated hundreds of npm dependencies in the process and reduced the build duration by over 99% (from > 7 minutes to < 6 seconds!) ### Software Engineer II @ Pindrop Jan 2018 – Jan 2020 | Atlanta, Georgia * Overhauled a monolithic legacy application into a modular React-based architecture resulting in over 85% code coverage and a 87% decrease in build time. * Programmed a performance testing utility which could simulate phone call data at a rate of over 2 billion calls a year. [Ruby, Rails, Bash] * Maintained performance critical code and implemented bottleneck-optimizations in a distributed high-performance application. [Ruby, Rails, Typescript, Python, Go] * Pushed for and executed an initiative to improve automated code linting in a legacy application. Oversaw a 93% reduction of lint warnings and errors. [Rubocop, Ruby, Rails] * Designed the architecture for a design system of reusable components. [React, Javascript, Typescript,Rollup] * Created a framework for building a unified UI which relied on GraphQL to allow for a modular system of backend/frontend interaction. [React, GraphQL, Apollo, JavaScript, Typescript] * Led application development team, provided subject matter expertise, and collaborated with other teams to build features which closed a multi-million dollar contract on time. ### Software Engineer @ Pindrop Jan 2017 – Jan 2018 | Atlanta, Georgia, United States * Improved data processing algorithms to decrease computation time by over 98% (from 218s to 3.5s). [SQL, Performance] * Designed and implemented continuous integration pipeline to improve efficiency of build process decreasing build time by 80% (from 25 min to < 5). [Ruby, CI/CD, Bash, DevEx] * Worked with multiple stakeholders to determine application requirements and implemented custom internal configuration management software. [React, Redux, Javascript, Flow.js] * Architected and implemented a reporting application capable of performing complex queries over vast datasets containing data about hundreds of millions of phone calls a year. [Ruby, Rails, Data Warehousing, Adhoc Reporting, Performance] ### Teacher's Assistant - Computer Security @ University of Illinois at Urbana-Champaign Jan 2017 – Jan 2017 | Urbana-Champaign, Illinois Area * Helped arrange lab activities to strengthen pragmatic cybersecurity skills. * Managed grading and planning of lab sessions. ### Software Engineer @ Networked Insights Jan 2016 – Jan 2016 | Chicago * Studied an existing architecture and created a drop-in replacement for a data collection service intended to replace a soon-to-be-deprecated API. [Java,Big Data, Data Firehose] * Refactored data collector API, identified inefficiencies, and improved performance by over 3x. [Optimization, Performance] * Migrated a polling approach to a pub-sub architecture bringing latency of realtime social media data to a consistent level. ### Software Engineer @ First Trust Jan 2015 – Jan 2015 | Wheaton, Illinois First Trust is a financial services company established in 1991 to offer trusted investment advice and services. This was a valuable internship because I was able to experience a lot of technology which went parallel to the eventual industry standard (think mercurial vs git). Highlights: * Developed an app to maintain FTP credentials * Automated testting FTP credentials, purging invalid configs, and detecting missing configuration values. ## Education ### Bachelor’s Degree in Computer Science University of Illinois Urbana-Champaign Jan 2013 – Jan 2017 ### Lockport Township High School Jan 2009 – Jan 2013 ## Contact & Social - LinkedIn: https://linkedin.com/in/jakub-klapacz - Website: https://k5z.dev --- Source: https://flows.cv/jakub JSON Resume: https://flows.cv/jakub/resume.json Last updated: 2026-03-22
