Full-time practice building AI-native platforms and the infrastructure under them: agent systems and guardrails, MCP servers, multi-provider model routing, durable orchestration. TypeScript end to end (NestJS, Next.js, React, Vue, React Native, Electron) on self-hosted Kubernetes I operate. Published 14 versioned NestJS packages to npm and an MCP server for my portfolio.

Technical owner of architecture and infrastructure for a booking platform used by about 1,000 people a day. Built it from the first commit (React Native apps, React dashboards, NestJS and GraphQL), merged seven codebases into one monorepo with gated CI/CD, shipped an npm booking widget, and moved the live system to self-hosted Kubernetes with no recorded downtime.

Fewer, larger engagements with end-to-end product ownership. Top Rated with a 100% Job Success Score and more than $62K earned; one client relationship across five contracts over nearly three years; paid architecture consultations for founders. Work spans React Native, Next.js, Electron, NestJS, PostgreSQL, Docker and Kubernetes, and increasingly the AI and agent layer.

Platform engineering on multi-tenant B2B SaaS: a shared-database architecture serving 1,000+ tenants with per-tenant credential isolation, fine-grained authorization in OpenFGA, durable workflows on Temporal, Stripe subscription and metered billing, and Kubernetes administration on GKE across staging and production. TypeScript, Node.js, NestJS, Vue 3 and PostgreSQL throughout.

Owned an AI workflow automation product line end to end and directed a distributed engineering team: agent-driven workflow design, LLM integration across multiple providers, and durable orchestration so long-running jobs resume instead of losing state.

Built and optimised software for school-district bus routing, trip and fleet management on the Athena platform, including a Field Trip Management module and improvements to admin dashboards and the routing, mapping and parent and driver portals.

Platform reliability and performance in a highly asynchronous distributed system: cross-stack debugging, safe database migrations, query tuning through indexing and refactoring, and more than 50 complex issues resolved in the first month.

Built a Bangla health and science platform with articles, videos, timed quizzes, a Q and A community and consultation booking on Node.js, Express and MongoDB. Handed over to the organisation's own team.
