Gontse Sebolai
Solutions engineer designing and shipping production systems for organisations that need reliable digital infrastructure.
Professional Profile
I'm a Computer and Information Sciences graduate (Web and Application Development, 2025) from Johannesburg, South Africa. I've built production web and mobile applications across freelance and academic environments — from payment-integrated platforms for non-profits to native Android apps for student productivity. My foundation spans C#, ASP.NET Core MVC, React, Next.js, TypeScript, SQL, and Microsoft Azure. I translate stakeholder requirements into maintainable, user-focused digital systems, and I care deeply about clean architecture, thorough testing, and shipping on time. Outside of code, I'm a passionate Arsenal FC supporter, a competitive gamer who's explored organising varsity eSports events, and someone who believes in continuous self-improvement — whether that's a 30-day fitness challenge or diving into a new cloud certification. I'm currently building Dev404 Labs, my own consultancy, to help South African businesses and organisations ship reliable digital products.
