About me
I'm Thieu Tran โ a Senior Software Engineer based in Hanoi, Vietnam, with 10+ years of experience building production systems for international product companies across FinTech, Healthcare, ERP, and Gaming.
I started in AI and computer vision, then spent four years at TJTech building Forex trading infrastructure from scratch โ CRM, trading engine, payment gateways, and 100+ automated bots โ as the company scaled from a small startup to 40+ people. Since 2022 I've worked exclusively with international remote teams: Finnish healthcare SaaS at OivaHealth, financial ERP modernization at Next One Technology (Sweden), and now loyalty rewards platforms at PLAYSTUDIOS (US).
I'm comfortable across the full stack and thrive in remote, distributed teams. I care about clean architecture, system design, and shipping software that actually scales in production.
