I'm a full-stack engineer with 9 years building production SaaS in remote startup teams. As a founding engineer I took a B2B platform from zero to 10M+ monthly events and owned the API, the real-time layer and the data pipeline behind it. I ship AI where it actually runs: RAG pipelines, conversational text-and-voice interfaces, and MCP tooling that exposes a product to external AI workflows. I've shipped on-chain too, with three Ethereum smart contracts and a React/Node marketplace that moved 3,000+ ETH. I like owning a feature from architecture through code review, and I work well in distributed teams.…I'm a full-stack engineer with 9 years building production SaaS in remote startup teams.

Centralized authorization as the single source of truth across orthogonal role axes, with row-level security maintained even when the client communicates directly with the database. Designed a credit system using expiring ledgers consumed FIFO via a Postgres function, debiting only on successful completion.

Processed and normalized external weather/turbulence feeds using Python serverless cron jobs, then passed gathered data to an LLM under rules so the model turns measured values into readable output without inventing numbers.

Shipped a RAG pipeline over product documentation, chunked into DB blocks and retrieved per question for both a docs site and a conversational widget. Built LLM-powered conversational surveys in text and voice with filler-word cleanup and background-noise handling so conversations remain uninterrupted. Implemented MCP tooling exposing product capabilities to external AI workflows and worked agent-first with Cursor/Claude Code, writing precise specs and reviewing outputs against team standards.
