# Steven L. > Senior Frontend Engineer (Uber) Location: New York, New York, United States Profile: https://flows.cv/stevenl Please check out my TypeScript/React/UX/DX articles: https://whalemade.medium.com ----- Coding has always been a part of my life. I've been coding since I was in middle school. I often have a bunch of side projects I am working on. I code at my job and then I go home and spend my free time designing and coding projects. I'm passionate, assertive, outspoken, motivated and a self-starter who is always ready to quickly learn new technologies and guide his fellow developers. In professional environments, I quickly pick up new responsibilities often finding myself in positions of leadership in team situations. I gain immense satisfaction from solving complex and challenging problems such as designing and implementing entire products from the ground up, that's why I've tried to expand my skills set as much as possible. ## Work Experience ### Senior Software Engineer @ Uber Jan 2022 – Present | New York, New York, United States Working on Observability/Infra Applications (like the stuff Datadog offers), focusing on Product, UI/UX, and FE Architecture all at the same time: Currently leading/co-leading on the following fronts: • Scaling Platform Alerts UX as it becomes the platform for standardized alerting for observability at Uber • Alert Debugging across Uber Observability tooling through a Chrome Extension to link tools by creating tab grouping sessions that auto sync tools • AI Chatbot Widget that leverages an internal LLM - defined, designed, built, and currently refining/evangelizing the entire FE/UI/UX/Product, architected to be a package which can be deeply integrated into all internal tools • Mixpanel TypeScript Package to make tracking events easy and consistent through type validation (refer to my Medium articles to see the type of TypeScript complexity this requires) --- Prior • UX and FE Code Architecture on Platform Alerts, a complex system designed to generate and manage alerts for services, improving observability and reducing noise • Scaling and Architecture on Frontend Engineering as our team has grown significantly and our products are shifting to a mature state • UX Design through an engineering lens (using first principles to define criteria to meet a product's novel needs and then designing exact UI/UX solutions that conform with the criteria) ### Lead Frontend Engineer - Tech Lead @ Bizly Jan 2022 – Jan 2022 Improving DX (developer experience) of venue booking SaaS software • Leading and developing features (React, Typescript, PHP, Laravel, SQL), allowing sales to retain and upsell Fortune 100 clients during pandemic • During turnover, working with customer success to define feature roadmap, filling in as PM, designer, and QA as needed • Providing complexity insight, leading agile rituals, Kanban management • Two semi-direct reports (work assignments, performance reviews) ### Senior Software Engineer @ Bizly Jan 2019 – Jan 2022 • Mentored developers on best practices (atomic commits, reverse engineering, async coding, etc.) • General feature development (React, Typescript, Laravel/PHP/SQL) • Created buy-in to invest in DX (systems, standards, type-safety, feature gates) to improve development speed, reduce bugs and downtime • Led feature development, providing complexity insight, breaking work into tickets, running routine meetings and maintaining product alignment HIGHLIGHTS: • Appeased a well-known client that prizes design, by developing a DX friendly theming system with our designer • Moderated a controversial feature’s alignment meeting, whiteboarding to explain everyone’s individual thoughts Developed a few systems: • Responsive modular email HTML/CSS templates with outlook supported full-page rounded corners (not just buttons) • React.js form system that balances consistency, flexibility, and DX • Unit testing system, with custom utilities to improve debugging experience ### Senior Frontend Engineer - UX Engineering @ Jet Jan 2019 – Jan 2019 • Led re-architecture of the frontend of a small acquired startup from jQuery to a modern TypeScript/React stack leveraging RxJS to build a basic RESTful transport/data caching layer • Advocated for modern development practices (deploy previews, continuous deployment/delivery) • Designed and implemented interfaces without needing to loop in a product designer • Mentored full stack developers on frontend best practices ### Frontend Engineer @ Percolate Inc.
