About

As a full-stack developer with approximately 4 years of experience, I love designing and optimizing systems that can solve real world problems. I was one of the founding engineers at Airwork AI, where I helped build and scale the platform to support 20K+ users. I designed and built major parts of the backend and led a full system rewrite, developing core ATS workflows for candidate shortlisting, interview scheduling, automated communication, and assignment management. I also built an assessment engine that automated the vetting and grading process for 10K+ submissions, and developed Elasticsearch and MongoDB-powered filtering and semantic search to help clients find the right talent faster. I later expanded into full-stack development, contributing to the frontend alongside my backend responsibilities. Alongside my work at Airwork AI, I worked with international clients on contract, taking ownership of frontend development with Next.js and backend engineering in Go. I worked across unfamiliar codebases and technology stacks, diagnosing complex issues, improving existing systems, and delivering production-ready solutions based on client requirements.
