What I'm looking for

I want to build secure, enterprise-grade products end-to-end, from system design to deployment. I’m excited to work across backend and frontend, improve performance and quality, and use AI agents to ship faster with reliable, maintainable code.

Senior full-stack engineer with 5+ years across Java/Spring Boot, Node.js/TypeScript, and .NET. Solo-designed and built a multi-tenant SaaS platform from zero to production (180Pi), and shipped features on a 100+ table legacy system serving 10,000+ users (Orange Group). Comfortable owning a problem end to end — data model, API, frontend, and deployment. 500+ LeetCode problems solved. Example: at Sofrecom, faced with slow API responses on a 100+ table legacy database serving 10,000+ users, I optimized queries and added caching — cutting response time by 40%.
