€1.6Mpre-seed raised by a client with an MVP I built
100%Job Success · Top Rated on Upwork
I turn manual, repetitive processes into automated systems and build the web and mobile apps around them. Most of my work sits where AI, integrations and product development meet: AI agents and chatbots on OpenAI, Claude and Gemini, multi-step workflows in n8n and Make, and full-stack apps on Bubble with Xano or on Next.js with Supabase.
I own projects end to end, from understanding the client's process to deployment, monitoring and support after launch. Reliability is part of the job: error handling, retries, validation and alerts are built in from day one, and my cybersecurity degree makes data protection a default, not an afterthought.
