What I'm looking for

I’m looking to build production-grade SaaS with secure multi-tenant design, microservices, and strong frontend craft—where I can own architecture, ship fast, and integrate real-world AI features responsibly.

I’m a Full Stack Engineer specializing in architecting production-grade SaaS platforms and microservices. I focus on building reliable, secure systems end-to-end—crisp frontends paired with robust backend services.

I’ve demonstrated a strong ability to reverse-engineer enterprise Open Source ERPs and translate complex requirements into maintainable architectures. I design secure multi-tenant systems with PostgreSQL Row-Level Security (RLS) and RBAC, and I’ve worked with enterprise patterns like CQRS, Event Sourcing, and Hexagonal Architecture.

In my recent work, I’ve built and evolved SaaS experiences across Angular, React, and Next.js, while implementing real-time and serverless backend logic using NestJS, Node.js, and Supabase Edge Functions (Deno). I’ve also engineered microservices that use API gateways for orchestration and real-time driver tracking with Socket.io and Redis for low-latency updates.

I enjoy taking on ambiguity and turning it into shipping software—whether it’s improving Auth UI in a 100k+ LoC ERP, integrating payment gateways with secure webhook verification, or integrating Generative AI agents using Gemini LLM and ElevenLabs. I’m especially drawn to teams that value secure architecture, thoughtful UX, and pragmatic delivery.
