I’m a Fullstack Software Engineer with 5 years of experience, focused on Node.js and TypeScript, building scalable systems end to end.
I’ve worked on multi-tenant architectures, API design, database modeling, Twilio integrations, AI-powered messaging flows, and time zone–aware job scheduling. I care about clean architecture, maintainability, and building systems that scale.
What makes me unique is that I think beyond implementation. I balance technical depth with product thinking, always considering long-term impact and system design.
I’m looking for a Senior Backend or Fullstack role where I can take ownership of backend architecture and contribute to building reliable, scalable systems on a long-term basis.
