About

Results-driven Full-Stack Software Engineer specializing in Node.js, TypeScript, React, and PostgreSQL. Proven track record of taking end-to-end ownership of web and mobile applications in fast-paced environments. Adept at architecting scalable full-stack data flows, managing DevOps deployments, and optimizing system performance, notably reducing API response times by 83% (600ms to <100ms).

Passionate about delivering reliable, production-ready code through rigorous testing and robust caching strategies.

Experience

Full-Stack Software Engineer at Lumiether Research (Startup) (2025-11 – Present)

Wrote the web and mobile apps from scratch using the MERN stack and Flutter — no handoffs, just end-to-end ownership across the entire product as part of a small startup team where everyone had to pull their weight across every layer.
Made both apps up to 6x faster (load times under 100ms) by hunting down slow queries, trimming frontend overhead, and adding Redis caching.
Rethought how data flows between React, Flutter, and the Node.js backend so the database doesn't buckle when traffic spikes.
Wrapped the backend in Docker so anyone on the team can run and deploy it without environment headaches.
Covered everything from the frontend to the APIs, and stayed on top of code reviews to keep bugs out of production.

Software Engineering Intern at Lumiether Research (Startup) (2025-04 – 2025-10)

Wrote Node.js/Express backend modules for core product features — clean REST endpoints backed by PostgreSQL schemas designed to keep latency low.
Wrote integration tests and ran Postman checks each sprint, catching bugs before they became someone else's problem.
Worked on Git feature branches, joined code reviews, and kept the backend reliable through consistent testing habits.

Full-Stack Developer at Freelancing (2024-11 – 2025-02)

Built a production art marketplace end to end (React.js, TypeScript, Node.js, Express.js, Supabase, Redis) — backend APIs, schema design, responsive frontend UX, and RBAC-driven full-stack data flows for real clients.
