Independent AI & Software Developer
Websites, AI Chatbots & Automations That Make Work Easier
I help startups, small businesses and agencies build practical digital solutions — from polished websites to AI-powered assistants and custom workflows.
2+ years of experience developing for startups, alongside leading technical projects and mentoring development teams.
Capacity & availability
- 5–10 hours per week — part-time, with a small number of active clients
- Replies within 1–2 business days
- I freelance part-time and keep a small number of active clients at once, so I take on clearly scoped projects rather than large full-time builds. Fixed-scope proposals keep both sides comfortable.
