Selected Projects
Production SaaS web platform for beauty studios — built solo from zero to production and validated by a real user today. Replaces fragmented WhatsApp + Google Sheets workflows with a structured operating system for beauty businesses.
- Built a complete management system: multi-tenant auth, client CRM, scheduling with Google Calendar sync, assisted messaging (WhatsApp), loyalty system, checkout & finance flows, multi-staff roles, per-role KPIs, automated reminders, and mobile-first UX.
- Full ownership across product definition, UX decisions, implementation, backlog management, debugging, and iteration.
- Production monitoring with Sentry, 45+ unit tests, strict TypeScript & ESLint — no escape hatches.
Mobile-first digital beer catalog and admin platform for a real tap room client — Nordic aesthetic, individual product pages, full CRUD admin with image uploads and status management. Staff use the admin panel daily in operations.
Personal website built end-to-end with AI as the execution engine — project showcase, positioning blog on AI-native development and vibe coding methodology, and internal prospecting automations connected to Claude, Gmail, and Notion.
Professional Experience
Help founders, brands, and operationally complex businesses turn friction and growth needs into clear digital systems — web-first MVPs, admin platforms, interactive catalogs, lightweight CRMs, operational copilots.
- Define what should be built, in what order, and with what level of complexity to match real business needs.
- Use AI-assisted workflows to accelerate discovery, prototyping, and build cycles without losing business judgment, usability, or operational focus.
- Played a key role in launching and structuring the company's B2B model, supporting growth from 20 → 200+ registered sellers and contributing to an approximate 1,900% ↑ GMV.
- Built systems for compliance, quality control, fraud prevention, operational follow-up, and process standardization in a fast-scaling marketplace environment.

AI Toolchain
"I use AI as an execution system, not as autocomplete. My workflow includes model-specific briefing files and persistent context systems to guide implementation, debugging, and architectural decisions."
Technical Approach
CLAUDE.md, AGENTS.md, GEMINI.md)What makes me different as a vibe coder: I don't just "ask AI for code" — I design the context system that makes AI produce coherent, maintainable, and correct code. I understand enough engineering to validate, debug, and make architectural decisions. And I understand enough product to avoid building what nobody needs. The result: complete digital products, live in production, with real users — built by one person.
