Elba Chimilio
Full-stack engineer & engineering manager — building platforms that real teams rely on, from healthcare analytics to infrastructure replicatiom.
I'm a full-stack engineer and engineering leader who enjoys building reliable, thoughtful products that people actually like using.
My experience spans full-stack development, front-end architecture, analytics platforms, infrastructure emulation, and design systems, with a strong focus on clean user experiences and scalable systems. I enjoy the mix of engineering, product, and design: improving workflows, mentoring teams, rebuilding interfaces, and solving performance problems.
Lately I've been exploring AI-assisted development, agent governance, and ways AI can help teams work more effectively all while continuing to strengthen my programming fundamentals.
Outside of work I love to draw, work on my nail art, read, and tackle DIY projects. On weekends you'll find me exploring New York City with friends. I also build websites and small projects for friends and small businesses, and enjoy experimenting with new ideas and technologies.
Explore some of my work below, and don't hesitate to reach out if you'd like to collaborate or build something together.
Where I've shipped.
- Lead end-to-end ownership of front-end and back-end architecture for a platform supporting ~6,000 users across 12 healthcare organizations, driving scalability, reliability, and technical strategy.
- Facilitate sprint planning and backlog prioritization, breaking down high-level product requirements into detailed technical tasks aligned with business goals.
- Mentor and manage a team of 6 engineers through biweekly 1:1s, performance reviews, and hands-on technical leadership — peer reviews and pair programming.
- Drove the migration from Postgres to a Snowflake-backed analytics layer, reducing chart load times from 2+ minutes to 5–8s — a 90%+ improvement in wait time.
- Led and implemented a full UI/UX redesign of the main application within 2 months — introducing TanStack React Router for routing and Tailwind to standardize the design system.
- Owned release management across client, API, and database layers, delivering bi-weekly production releases via automated Jenkins pipelines with detailed versioning and documentation.
- Built full-stack data visualization tools with React, TypeScript and Recharts — optimizing APIs, SQL queries, and database migrations for fast analysis of large-scale EHR and clinical datasets.
- Delivered a greenfield project within 6 months — authentication, API, database integrations and 10+ analytics dashboards for pharmaceutical data insights.
- Developed 50+ reusable and maintainable front-end components using React, TypeScript, Material-UI and MobX — enabling the app to virtually replicate entire business infrastructures.
- Debugged, contributed to and tested the API and back-end infrastructure using GraphQL, NestJS and Insomnia, reducing bug reports by over 60%.
- Met Scrum requirements across two-week sprints, leading the web app from build v2.0 to v3.0 in 7 months — 15 epics and 75 stories shipped.
- Optimized and maintained a Project Management and Ticketing System for desktop, tablet and mobile using React, DynamoDB, HTML5 and SCSS/CSS.
- Integrated front-end design patterns — asynchronicity, data binding, object-oriented programming and promises — which reduced API calls by over 20%.
- Collaborated on a daily basis with UX/UI, Middleware, Backend, and DevOps teams to implement and troubleshoot new and existing features and completed all of our own User Testing.
- Established individual goals to monitor code progress and quality through personal and peer code reviews, pair programming, and proper GitHub PR and code documentation.
Things I've built, in pieces.
Projects coming soon — stay tuned.
A little elsewhere.
Code is most of the day. This is the rest of it — books, coffee, runs, time outdoors, and the occasional notebook full of half-finished ideas.
