I'm Naga Venkatesh — a full-stack engineer with 7+ years shipping products end-to-end. Pixel-careful React & Next.js on the surface; Node.js, Redis and real-time pipelines underneath. FinTech, EdTech, and my own studio, LevnTech.

01 — what I build
Built end-to-end, on both sides of the wire.
Most products break at the seams between front and back. I work on both sides, so the seam is mine to get right.
APIs & services
REST and GraphQL on Node.js and TypeScript. Typed contracts, auth, role-based access, background workers.
JWT + RBAC across three user rolesReal-time systems
Socket.IO with Redis adapters, Kafka pipelines, and live dashboards that stay in sync at scale.
Live K-12 classrooms & market dataAI integration
OpenAI and Claude APIs, LangChain and RAG pipelines — wired into products where they earn their place.
Chatbots · document processing · content02 — how a request travels
Watch one click travel the stack.
Every tap on the front end starts a journey through the back end. This is the path I design for — send a request and follow it, cold or cached.

- 1
Click
The UI updates optimistically — the user never waits on the network to see a change.
- 2
Route
The edge resolves the route and checks the session before anything heavier runs.
- 3
Validate
Node validates the payload against a typed contract and applies the business rules.
- 4
Read
Redis answers hot reads in about a millisecond; a miss falls through to Postgres and re-warms the cache.
- 5
Respond & broadcast
The response confirms the change, and Socket.IO pushes it live to every other client.
03 — the stack
One engineer, every layer.
From the pixel to the packet to the pod. Here's the toolbox, layer by layer — and where each tool has earned its keep.

05 — the path so far
From the pixel down to the packet.
I started on the front end, went deep on the back end, and now build the whole thing. Pick a stop.
2025 – Present
Founder & Full-Stack Engineer
LevnTech & LevnTools
Ship products end-to-end for global clients — interfaces, APIs, data and deploys — wire in AI/LLM where it earns its place, and build LevnTools.
06 — who I am
Or just ask the terminal.
I'm a full-stack engineer in Hyderabad. I spent my early years making interfaces fast and friendly, then went deep on what powers them — schemas that scale, queries that stay fast, real-time services that refuse to fall over.
Today I run LevnTech, shipping products end-to-end for clients worldwide, and building LevnTools on the side. I bring in AI and LLMs where they actually help — not because they’re trending.
- 01Boring in production
The best backend is the one nobody pages about at 3am.
- 02Felt, not noticed
Good UI removes decisions. Motion has a job, or it goes.
- 03Own the seam
Contracts, types and errors designed once — shared by both sides.
