Backend Developer Intern
Gyanama
- Architected a service-layer Node.js and Express backend for a multi-tenant school platform, exposing 145+ REST API endpoints across 20 routers for auth, academics, attendance, messaging, and admin operations.
- Secured the API with stateless JWT authentication (15-min access / 30-day refresh) featuring token-version rotation to detect reuse, plus 5-role RBAC enforced through centralized Express middleware for validation and error handling.
- Optimized MongoDB performance with 60+ compound indexes and a dual-layer cache (Redis with in-memory fallback) using pattern-based invalidation and distributed locking.
- Lowered read latency on high-traffic endpoints by serving repeat requests from a cache-first layer, falling back to index-backed queries with lightweight lean() projections and a pooled connection setup (10–50 sockets) to avoid full collection scans.
- Deployed a 2-instance PM2 cluster behind Nginx (SSL/TLS termination), with a GitHub Actions CI/CD pipeline performing zero-downtime reloads; integrated Cloudflare R2 object storage via signed URLs.
Backend Engineer
Freelance
- Built a real-time, bidirectional voice AI agent on the Google Gemini Live API over WebSockets with Telnyx telephony, streaming 16-bit linear PCM (L16) audio for natural spoken conversations.
- Engineered a low-latency async pipeline with 24kHz to 16kHz resampling, barge-in interruption via voice activity detection and stream-clear signaling, and three concurrent asyncio loops; instrumented P95 time-to-first-audio monitoring with an 800ms alert threshold.
- Implemented a Gemini session pre-warming pool and a supervisor loop (silence detection, max-duration hangup) to avoid cold-start connection delay and improve call reliability.
Projects
YapYap – Real-Time Chat Application
View Project- Built a real-time chat app with Socket.io, using Redis to track which users are online and deliver each message only to the intended recipient, plus live typing indicators.
- Secured login with bcrypt password hashing and JWT stored in HTTP-only cookies, and applied the same auth to the WebSocket connection.
- Organized the backend with a clean Controller–Service–Model structure that checks a user belongs to a conversation before saving and sending their message, storing chats in MongoDB.
Assignmento – AI Assessment Generator
View Project- Implemented a background job queue (BullMQ + Redis) to move slow AI generation off the request path into a worker, with automatic retries on failure.
- Delivered real-time, event-driven status updates over Socket.io room subscriptions, pushing queued/processing/complete states over a live connection instead of polling.
- Engineered structured LLM output via JSON-schema prompt engineering and a validation layer with defensive parsing, ensuring responses conform to the expected schema before persistence to MongoDB.
SecureStorage
View Project- Developed a secure document platform with Google OAuth 2.0 (Passport) and JWT-protected REST APIs for stateless authentication.
- Enforced per-user data isolation at the query level, scoping every read and delete to the authenticated owner’s indexed userId to prevent cross-user access.
- Developed a file-upload feature that handles large files by streaming them to Cloudinary cloud storage, with cleanup of temporary files after each upload.
