What I'm looking for

I’m looking to build scalable SaaS and high-performance web apps with a focus on clean architecture, fast delivery, and reliability. I want to work on challenging systems, collaborate closely across product/design, and mentor teammates while optimizing development workflows.

I’m a Senior Full-Stack Developer with 7+ years of experience designing, building, and scaling high-performance web applications and SaaS platforms end to end—from system design through deployment. I focus on clean, maintainable systems while making architectural decisions that improve scalability, performance, and reliability.

In my recent roles, I’ve led architecture and development across frontend, backend, and cloud infrastructure. I’ve built microservices using Node.js, Express, FastAPI, and AWS serverless components, developed secure authentication and RBAC, and improved performance with Redis caching and background job workers to reduce API latency.

I also enjoy solving complex technical challenges and delivering reliable, user-focused products by collaborating closely with founders, product managers, and designers. I mentor developers, define coding standards, and optimize development workflows—whether integrating services like Stripe, HubSpot, and Twilio or deploying and maintaining AWS infrastructure reliably.
