What I'm looking for

I’m looking to build and scale end-to-end SaaS products—owning architecture, APIs, UI, and cloud performance—while improving reliability through CI/CD, testing, and observability in collaborative agile teams.

I’m a Senior Full Stack Engineer with 9+ years of experience building and scaling SaaS platforms across fintech, e-commerce, and enterprise domains. I bring strong expertise in Node.js, TypeScript, Python, React, PostgreSQL, MongoDB, Redis, and API architecture, delivering end-to-end features from design to production. I’m especially focused on improving performance and reliability while driving engineering quality through CI/CD, testing, and observability in distributed agile teams.

Most recently at Coursedog, I built full-stack capabilities across Node.js services, React interfaces, and Python backend systems for a SaaS platform serving 500+ institutions. I improved PostgreSQL performance by 25% on high-traffic endpoints and reduced deployment time by 40% by improving CI/CD with GitHub Actions and Docker, while mentoring engineers through design and performance-focused code reviews. Previously, I reduced latency by 60% through MongoDB schema improvements and Redis caching strategies, built async pipelines with Celery and RabbitMQ, and improved API response times by 30% via SQL tuning and indexing—always pairing clean architecture and multi-tenant design with proactive monitoring and release safety.
