Full-stack engineer with four years of shipping products end to end, from the interface down to the database. Lately I've been building the backend of AI developer tools: ingestion pipelines, retrieval and MCP servers.

AI infrastructure and agents
Code ingestion and retrieval pipelines, MCP servers, model routing backed by evals, and agents with memory and streaming. At Bytebell I owned the ingestion engine, cutting its cost by ~50% and retrieval latency by ~60%.

Backend systems
APIs, queue-driven workers and data models in Postgres, MongoDB and Neo4j. At Router Protocol I ran a NestJS and Postgres rewards backend for ~1,200 daily users and improved its query performance by ~40%.

Full-stack products
Complete web apps with a clean UI, built with Next.js, React or Vue on the front and NestJS or Node behind it. I built the cross-chain swap interface for Router Nitro, and today I build dashboards and internal tools for clients.

Data pipelines and automation
Scrapers and scheduled ingestion jobs that check their own output and fail safely instead of shipping bad data.

Web3 and cross-chain
Bridges, wallet SDKs, smart contracts and on-chain payments. I shipped direct CEX withdrawals across 30+ chains and co-built a React wallet SDK that spans 8 ecosystems.

Developer tools
Browser and VS Code extensions, npm packages and CLIs, plus the docs that get developers productive. At ThirdFi I onboarded 1,000+ developers.

• Spinneret: a scraping pipeline that repairs itself in CI and can tell a broken scraper from a real price change.
• Palladium: an explorer and REST API for every Avalanche L1, fed by a four-stage ingestion pipeline into time-series Postgres.
• Clarity: turns ChatGPT share links into summaries, action items and interactive mind maps.
• chat-agent-backend: a compact agent runtime with session memory, optional RAG and streaming responses.
• Terms Simplified: a Chrome extension that flags harmful clauses in terms and conditions before you accept them.
• safe-deploy: deploy smart contracts from the CLI and sign with MetaMask in the browser, so your private key never touches your dev environment. 500+ downloads.

More projects and write-ups are on ankitsingh.xyz.

• Bytebell: AI context engine for codebases. I owned code ingestion and the GitHub, GitLab and Bitbucket connectors.
• Router Protocol: cross-chain swaps and bridging. I built the swap interface, CEX withdrawals and the rewards backend.
• Meme Duels: a real-time Web3 game on Solana that I built from scratch.
• ThirdFi: DeFi APIs. I ran developer relations, docs and workshops.
• Freelance: web apps, dashboards and internal tools for clients.
