What I'm looking for

I’m looking for a product-focused team where I can build scalable full-stack SaaS, improve performance with caching and resilient pipelines, and apply AI/ML (RAG/LLMs) to deliver measurable user value.

I’m a Software Engineer focused on building production-ready products, from scalable backends to polished frontends. I shipped an email marketing engine with RFC 8058 compliant one-click unsubscribes and iCalendar (.ics) integration, plus real-time engagement tracking using pixels and redirect endpoints.

At KothonTech, I implemented an Admin Panel with organization management and RLS-protected database policies, and refactored the email configuration hierarchy (Mailing > Event > Organization) to enable granular SMTP control across the SaaS platform.

Earlier, I built a full-stack SaaS advertising platform connecting advertisers with 300+ streamers using Next.js and Strapi with PostgreSQL. I also orchestrated an automated ad injection pipeline with Trigger.dev for 100+ concurrent streams and reduced database CPU load by 60% using Redis while adding resilient error-handling strategies during third-party outages.
