Summary
Sadat Kollan is a hands-on Chief Technology Officer with nine years of experience building and scaling high-performance web and mobile platforms across fintech, e-commerce, and SaaS. He blends deep full‑stack expertise (PHP, Laravel, Symfony, Next.js, Java/Spring Boot, Redis, RabbitMQ, MySQL) with proven operational know‑how—optimizing nginx, load balancing, caching and CI/CD to serve tens of thousands of concurrent users. As Principal Engineer and engineering leader, he has led teams of 6–8 engineers to deliver USSD services, remittance backends, chatbots, and an AI-powered SaaS built on Llama2/OpenAI, demonstrating fluency from infrastructure to model deployment. His track record includes mission‑critical banking and mobile money integrations, large-scale USSD products, and a knack for pragmatic performance tuning under constrained environments. Based in Accra, he combines technical leadership with mentoring and process discipline (SOLID, DRY, testing, agile) to drive product outcomes. A detail that often goes unnoticed: he repeatedly bridges legacy PHP systems and modern stacks (Next.js/Prisma, Spring Boot) to unlock new capabilities without disruptive rewrites.
