Most AI projects and automation scripts work well in a quick demo, but run into trouble once they hit real-world conditions. APIs timeout, website layouts change, Cloudflare blocks scrapers, or edge cases crash the pipeline.

I help founders and engineering teams build reliable, production-ready AI applications, web automations, and modern full-stack tools that keep running smoothly without constant babysitting.

Over the past few years, I have worked as a core engineer for venture-backed AI companies, including XY.AI Labs building multimodal browser agents and healthcare workflow systems, as well as partnering directly with independent founders on end-to-end products.

I take pride in writing clean, well-tested code, communicating clearly at every step, and leaving codebases in better shape than I found them.

WHAT I CAN HELP YOU BUILD

► AI Agents and Practical Workflow Automation
▪ Long-running, fault-tolerant Python pipelines with automated retries and failure recovery using Temporal, Celery, and Redis.
▪ Human-in-the-loop review stations where AI drafts proposals, claims, data extraction, and reports for human validation before execution.
▪ Controlled, source-grounded LLM systems using OpenAI, Claude, and Gemini with schema validation via Pydantic to avoid hallucinations.

► Browser Automation and Chrome Extensions
▪ Manifest V3 Chrome extensions with background service workers, content scripts, and clean side panel interfaces.
▪ Deep browser automation using Chrome DevTools Protocol, handling shadow DOM, nested iframes, and persistent login states.
▪ Resilient web scraping engines that handle Cloudflare protections, dynamic single-page apps, and pagination without getting stuck.
▪ Model Context Protocol servers and Python SDKs for programmatic browser control.

► Modern Full-Stack Applications
▪ Frontends built with Next.js App Router, React, TypeScript, Tailwind CSS, and shadcn/ui.
▪ Clean, type-safe API layers using tRPC, FastAPI, and gRPC microservices.
▪ Real-time data streaming, interactive charts, and responsive dashboards.

► Data Platforms and Internal Tools
▪ Interactive data apps and internal admin tools built with Streamlit and Next.js.
▪ PostgreSQL database design with SQLAlchemy and clean Alembic migrations.
▪ Governed semantic analytics using Google BigQuery and Cube.dev.
