Rockstar🎓
Top SchoolMarcell Da Silva is an independent entrepreneur and seasoned software engineer with 11 years of experience building resilient backend systems, real-time communications, and fintech products from Brazil’s Rio Grande do Norte. He excels in Elixir, Phoenix, WebRTC, PostgreSQL and distributed architectures, having implemented production-grade features like a shared-payment credit card with Saga-pattern orchestration and an NP-complete knapsack-based optimizer to reduce declined payments. He’s shipped whole-stack MVPs for telemedicine and collaboration platforms, prototyped video-filter and WebRTC integration libraries, and helped teams adopt CI/CD, testing culture, and observability. As a hands-on tech lead he defined career paths, reduced turnover, and created a reusable UI design system that accelerated migrations across legacy apps. Comfortable both as contractor and staff engineer, he contributes to open-source Elixir libraries and brings a pragmatic mix of algorithmic thinking and product-focused engineering. Notably, he pairs fintech reliability with real-time media expertise—an uncommon dual specialty that fuels creative, high-impact solutions.
