What I'm looking for

I’m looking to lead and build in remote-first, async teams—integrating AI/LLM-powered features responsibly. I want ownership of architecture, strong engineering practices (testing/CI/security), and room to mentor others while shipping measurable product improvements.

I’m a Senior AI Full Stack Engineer with 9 years of hands-on experience architecting and shipping production-grade web applications using TypeScript, Node.js, and React-based stacks. I lead with deep expertise in REST and GraphQL API design, containerization, and OWASP-compliant security, pairing it with disciplined unit/integration testing and CI/CD automation to keep quality high.

As a tech lead, I’ve directed engineering execution across 15 concurrent client projects—improving ticket completion rate by 85% through a redesigned onboarding workflow, reducing production bug volume by 20%, and cutting average ticket cycle time by 20% with proactive monitoring and unblocking. I’m an early adopter of AI tooling, integrating LLM-powered features and AI-assisted workflows into product development while mentoring junior and mid-level engineers in remote-first, asynchronous distributed teams.
