Tejas Nafde
I build backend systems, real-time infrastructure, and developer tools. Currently engineering at GeoIQ. BITS Pilani, Goa alumnus.
Experience
- Own an end-to-end automated pipeline that transforms survey data into client-specific presentations, generating each in 30s–5min.
- Designed a decorator-based caching layer with conditional invalidation — reduced API latency by 80% for cached sections.
- Built a standalone payment and invoicing service with idempotent verification and webhook-driven state management.
- Architected a real-time messaging platform used across three production applications using WebSockets and Pub/Sub.
- Integrated telephony with automated call summaries, shared broker notes, and webhook-driven state tracking.
- Built a FastAPI WebSocket gateway with room-based messaging and centralized connection lifecycle management.
- Developed Slack-based admin tooling with approval workflows for safe GCP Compute Engine operations.
- Designed a feature-flagged multi-channel notification system (push, WhatsApp, email) with delivery-state tracking.
Featured Projects
Desktop notebook app with a bidirectional sync engine that maintains a token-efficient .py mirror of .ipynb files, reducing LLM token usage by 70%+. Diff review UI for accepting or rejecting AI-suggested edits cell by cell.
Real-time shared viewing platform with room-based sync, live chat, and a media bridge service. Full-stack with a Next.js frontend and FastAPI + Socket.IO backend.
Pipeline that generates engineering blog posts from git commit history using Gemini. Discovers repos, extracts commits, batches by week or month, and produces structured technical narratives on a weekly schedule.
Other Work
Hardware communication layer for a remote phoropter. Real-time serial comms with a custom binary protocol (SOH/CR/EOT).
Lenskart Hackathon — Special Mention
Production bot for Factorio multiplayer servers. WebSocket real-time updates, REST lifecycle control, dual-layer state persistence.
Research bot with multi-LLM fallback (Gemini, Groq, HuggingFace). Scrapes sources, ranks with semantic embeddings, delivers cited analysis.
Personal Software
Tools built to solve a problem once.
Agent workspace. Reaches work VMs over IAP WebSocket tunnels, so it needs no VPN and no routable SSH port.
Shared memory for friendships. Keeps track of the things you said you would get around to doing together.
Your Mac, in your pocket. A FastAPI control server paired with a Hammerspoon bridge and a browser extension.
Fast dictation. Low-latency speech capture wired straight into whatever has focus.
Tools & Stack
Let's talk.
Open to interesting conversations about engineering, side projects, or new opportunities.
