System Architecture & Engineering
Sunanda Samanta.
I architect systems that scale.
I write code that actually solves problems instead of just pushing tickets. Most of my day is spent designing databases, fighting with Rust integrations on Solana, or building out infrastructure that can handle heavy traffic.
01. Core Capabilities
AI & Data Engineering
I build RAG pipelines that actually work in production. Hooking up LLMs to internal company data using Python and vector databases so they don't hallucinate.
High-Frequency Web3
Writing bare-metal Rust to interact with Solana and Polygon RPC nodes. Mostly building arbitrage bots to execute flash loans faster than the competition.
Backend Infrastructure
Keeping APIs fast and servers from crashing. I write a lot of Node.js and Spring Boot, and spend way too much time optimizing Graph and SQL queries across AWS.
Full-Stack Product
When I'm not in the backend, I actually enjoy building the interfaces. I usually reach for Next.js or React, and use Flutter if we need a mobile app yesterday.
02. Professional Impact
Software Engineer
Perpetuum Innovations Pvt. Ltd. (Reve)
- Leading the backend and architecture for a social discovery ticketing startup.
- Writing the core codebase that handles user transactions and real-time events.
- Also managing the Flutter mobile app to keep our cross-platform deployments moving quickly.
Full-Stack Developer
VebHolic Pvt. Ltd.
- Built out complete Node.js backends for various B2B clients.
- Focused heavily on making sure the servers didn't crash when traffic spiked.
03. Midnight Hacks & Side Quests
Some of the stuff I build just for fun. Mostly weekend projects, proof-of-concepts, and bots where I get to dive deep into weird protocols or solve hard engineering problems without the pressure of a product roadmap.
devutils.lol
A suite of developer tools that run entirely in the browser. I moved all the heavy data transformations into Web Workers so zero data ever hits a server.
GIF-VPN
A fun proof-of-concept where I bypassed Deep Packet Inspection by disguising a headless browser session as an infinite MJPEG "GIF", hiding keystrokes inside 1x1 image uploads.
Infinite-GIF
A trick using HTTP Refresh headers to stream live data (like crypto prices or server stats) directly into static markdown files and emails using dynamically generated Canvas images.
Algorithmic Trading (MEV)
Wrote some custom Rust bare-metal infra to talk to RPC nodes. It doesn't just calculate arbitrage loops—it actively pulls flash loans and executes real transactions on-chain through Jito.
LLM RAG Pipeline
Hooked up an LLM to a vector database full of company data so users could actually ask questions about internal docs without the bot hallucinating.
04. What's Next?
Let's talk code.
