Priyanka Chatterjee
3+ years building distributed, event-driven systems in Node.js and Go across AWS, Azure, GCP, OCI, and AliCloud. Core contributor to four open-source products.
Experience
Roles in reverse chronological order.
Building Guardrails (preventive cloud governance) and contributing to all four Turbot OSS products. AWS SDK v2→v3 migration across 11+ services, Azure Event Grid push-eventing across 35+ modules (70–90% latency cut), PostgreSQL query optimization, and an LLM-driven CIS mod orchestrator.
Hands-on multi-cloud (AWS, Azure, GCP, Alibaba, OCI) infrastructure work. Authored the Microsoft 365 compliance benchmark from scratch within the first month, then expanded to AWS and Azure compliance modules.
Built a 3D-geometry library (computational-geometry algorithms for footprint extraction) for the room-design product, introduced the repo's first Mocha unit-test setup, and led the user-upload workflow redesign across 60+ files.
React + Firebase PDF-sharing platform with chat, upvotes, push (OneSignal), and email (Sendgrid) notifications.
Solo-built a pet-grooming website end-to-end in React + Firebase: Google/Facebook auth, slot booking via Cloud Firestore.
Financial subscription platform: stock screener + News-API feed in React/Vanilla.JS, MySQL backend, PHP server-side scripting, CSV upload pipeline.
Revamped the company website with a HTML/CSS/JS frontend backed by Firebase.

Featured Projects
A mix of distributed-system, backend-API, and AI-tooling work. Ordered by backend-engineering relevance.
1.Lila Tic-Tac-Toe
Real-time multiplayer game with server-authoritative anti-cheat. Tick-based turn timer, mode-aware matchmaking via KV-storage queues, reconnect-into-active-match. Built end-to-end in 4 days.
2.Tasks REST API
Task-management layer with prepared-statement CRUD, JWT auth, and Zod schema validation. Status enum, REST status codes (201/204/400/404), SQLite migration.
3.AI Agent with MCP
