Top SchoolTrần Tuấn is a versatile software professional and freelance tech lead with 10 years of experience spanning product ownership, Android and backend development, cybersecurity, and technical presales. He has led teams and projects across startups and enterprises—from building NFV mobile platforms and OCR products to managing e-commerce, laundry chain, and court-rental systems—combining hands-on engineering with product strategy and business analysis. As former CTO of a cyber security firm he built pentest and SOC teams, managed infrastructure, and contributed to company strategy while holding CEH and ISO-based risk management training. Comfortable switching between roles, he bridges technical depth (Java Spring, Docker, MongoDB, Android) and customer-facing delivery, often translating complex requirements into practical systems. Based in Hà Nội with a background in Applied Mathematics, he brings an analytical mindset and a personal mission to create technology that delivers “happiness value” to users and communities. An underrated strength is his track record of turning security and low-level analysis experience into pragmatic product decisions that reduce risk while accelerating delivery.
