QA Automation Engineer (SDET) in fintech & payments. I also build apps for small businesses. Every project, with an interactive demo: licman.dev Da Nang, Vietnam · working remotely
- Test automation for banking and payments. I build backend test frameworks for instant-payment systems and SWIFT MT / ISO 20022 MX messaging, in Kotlin (BDD with Cucumber/Gherkin) and Python, wired into Jenkins with Allure reporting.
- Help teams test faster. I wrote test steps in business language and onboarded 6 manual testers into writing automated scenarios themselves. Smoke and E2E testing across several projects went from days to hours (about 4–6x faster).
- Build products for small businesses. These are full-stack apps I design and ship myself, using an AI-agentic workflow with Claude Code.
Rahat Go is a Telegram Mini App and CRM for a bakery in Da Nang. Customers order and pay inside Telegram. Staff run orders, a POS, stock, dine-in tables, and per-dish profit analytics in the same app. The bakery's staff used it for 3+ months.
