What I'm looking for

I’m looking for a role where I can own architecture and lead delivery—building scalable Laravel/Next.js platforms, 600+ API-style services, payments, search, and LLM-powered features like RAG/vector search—across teams in any time zone.

I’m a Senior Software Engineer with 9+ years building platforms at scale, currently a technical lead for atb-jobs.com. I own architecture and deliver a 600+ endpoint API, payments, search, and CI/CD, leading a cross-functional team of ~10 while serving 330,000+ job seekers and 10,000+ employers. I’ve also improved system response time by 30% through query and endpoint redesign and are actively building LLM-powered features like RAG, vector search, and tool-calling agents.

Previously at AGAMiLabs Limited, I was promoted from Associate to Senior Software Engineer and led a team of 8 developers. I architected and shipped major systems including a University Admission System and education ERP/result processing platforms, plus Ghorket eCommerce with an integrated POS. I bring strong fundamentals from competitive programming (ICPC/NCPC, LeetCode/Codeforces/UVa) and I’m especially motivated by building reliable, production-grade engineering with clear coding standards, Agile delivery, and measurable impact.
