I build web apps, WordPress sites and AI automations end to end: Next.js, NestJS, PostgreSQL, PHP and the Claude API. 5+ years in fintech, SaaS and HR platforms.
Recent work: custom WordPress plugins and block themes, a hub that publishes posts to many WordPress sites through the REST API, an AI lead intake with HubSpot and Slack, and a RAG chat that answers from your docs.
You get a clear plan and estimate first, regular demos, and clean, tested code.

FAQ
Can you move my data from spreadsheets or my current CRM?
Yes. CSV/Excel import is included from the Standard package. Migration from HubSpot, Pipedrive or another CRM via API is included in Premium.
Who owns the code and where is it hosted?
You do. You get the full source code and setup docs. I deploy it to your own server or cloud (AWS, DigitalOcean, Vercel, etc.), so hosting is in your name and there are no per-seat fees.
Can you add features after delivery?
Yes. The code is modular, so new modules, reports or integrations can be added later through a custom offer.
Will it work on phones?
Yes. It is a responsive web app, so your team can use it in the browser on desktop, tablet and phone. No app store install needed.
What support do you offer after launch?
Every package includes 7 days of free bug fixes after delivery. After that I can provide ongoing support or new features through a custom offer.
