I'm a Senior Product Engineer. I build AI and full-stack products and take them from architecture to the user-facing layer, with 6+ years shipping across AI products, SaaS, and Web3.

Recently I built and shipped Amarnai, an open-source AI email-triage product, solo, from first commit to live users.

• Product & Frontend — React, Next.js, TypeScript, React Native
• Backend & APIs — Node.js, NestJS, REST/GraphQL, PostgreSQL, data modeling and indexing
• AI / LLM Integration — products built on frontier models: structured outputs, embedding-based routing, agentic flows, privacy-conscious design
• Web3 & Smart Contracts — Solidity, Hardhat, ethers.js, The Graph; DeFi products in production securing tens of millions in TVL

Gmail-first AI triage that sorts an inbox into folders defined in plain English, drafts replies for approval, and shows its confidence and reasoning on every routing decision. Built full-stack, solo.

• Plain-English taxonomy — describe each folder in a sentence; no rules, no code
• AI-drafted replies — generated for review, never sent without approval
• Confidence + reasoning — low-confidence threads routed to review instead of guessing
• Privacy by design — read-only Gmail OAuth, no email bodies stored
• Open-source (AGPL-3.0) — hosted, or self-host with Docker against any model (including local Ollama)
• Next.js, Node/TypeScript, PostgreSQL/Prisma, embedding-based routing, frontier-model integration end to end → amarnai.com · github.com/amarnai/amarnai

Frontend lead for VeChain's Stargate staking platform, supporting the network's transition from Proof of Authority to Delegated Proof of Stake.

• Owned frontend architecture and UX-critical flows
• Designed and implemented NFT-based staking and validation node management
• Supported a platform that peaked at $100M+ in assets staked across 6,000+ NFT holders → stargate.vechain.org

Instant upfront-yield DeFi protocol. Owned delivery from smart-contract integration to frontend architecture.

• Built production React/Next.js dApp interfaces tightly coupled with protocol mechanics
• Reached a $40M+ market cap and $20M+ in total value locked
