I work at both ends of a product. Schema design, REST boundaries, authentication and query plans at one end. Retrieval pipelines, agent workflows and model inference at the other. Most of what I have released, I owned alone, from the first migration through to the production page at 2am.

Nysonian Inc.
- eCommerce platforms and internal tools on Next.js, React, TypeScript, Node.js, Python and FastAPI, covering order management, shipping, support and daily operations.
- AI features over PostgreSQL databases holding millions of customer records, so staff query business data in plain language instead of writing SQL.
- An AI content management system that absorbs repeat internal work for the operations team, plus cross department automation on LangChain and n8n.
- Shopify and ShipHero wired into internal services so order fulfillment and inventory stay in sync without manual entry.
- Deployment and infrastructure on AWS, including the release process, uptime and production triage.
NESL-IT
- Sole developer on AI SaaS products, owning system design, database schema, frontend, backend and production release.
- LLM pipelines and agent workflows on LangChain and the OpenAI API, for work that previously needed a person at every step.
- Modular Node.js services along microservices lines with clear REST boundaries, so parts of the product scale on their own.
- Frontend in Next.js and React with TypeScript: authentication, dashboards, and the screens users sit in all day.
- CI/CD through Vercel and GitHub Actions, so releases repeat without a checklist.
