Co-Founder & CTO
B2B SaaS for events & networking: digital business cards (NFC/QR), lead capture and CRM, team workspaces.
- Sole engineer: took a two-week prototype to a complete production B2B SaaS for event lead capture, with Claude Code as the main engineering environment.
- Agentic QA with jev, Browser Use's browser agent: it signs in to the test app as each account state (free, Pro, lapsed, team member, frozen team) and follows a plain-English goal, then a SQL query, not the agent, gives the verdict. 16 standing checks on plan gates and permissions; its before/after screenshots on closed tickets surfaced 3 follow-up bugs. Open-sourced as jev-check.
- Shipped an AI business-card scanner: vision LLM with strict JSON output, a per-user quota and on-device OCR as the last resort; chose the cross-provider fallback by prompt-injection testing (2 of 4 candidate models obeyed an injected card).
- Live Stripe billing (checkout, customer portal, webhooks, per-seat team plans, scheduled reconciliation) and multi-tenant workspaces secured by Postgres row-level security and role-based permissions; billing and permission code is reviewed by a different model from the one that wrote it.
- Android app live on Google Play and iOS build from the same codebase (Capacitor), Apple and Google Wallet passes, CRM sync and a Zapier integration.
- Unit and Playwright tests gate CI/CD across separate test and production environments.
