About
I've built full-stack web applications at Startup Agile and GNK Technology Solutions, using Next.js, React, Node.js, FastAPI, Django, and PostgreSQL to support real operational and customer-facing workflows.
At Startup Agile, I helped scale applications to 10,000+ monthly active users, reduced API response times by 30%, and delivered 15+ major feature releases with a cross-functional team. At GNK, I built a transport management system that improved logistics-team operational efficiency by 30%.
I also create reliable developer workflows and products, from Dockerized software-engineering tasks and deterministic test suites at Afterquery to project-management APIs, AI-enabled research platforms, and B2B sourcing tools. I enjoy teaching practical software development and have led coding classes for 90+ students.
