Top SchoolKolawole Oyafajo is a Lead Software Engineer with eight years of hands-on experience building and scaling distributed, event-driven backend systems for payments and e‑commerce across AWS and GCP. He specializes in TypeScript (Node.js, NestJS, Fastify), Java (Spring Boot) and PHP (Laravel), and has repeatedly delivered high-availability APIs, microservices and CI/CD pipelines that improved system performance and uptime for production payment platforms. Kolawole brings deep expertise in messaging (Kafka, RabbitMQ, MQTT, SQS, Pub/Sub), CQRS/eventual consistency patterns, and both relational and NoSQL data modeling tuned for millions of records. He pairs technical leadership—mentoring teams, enforcing code quality, and driving migrations from monoliths to microservices—with a pragmatic focus on observability, security (OAuth2/JWT/RBAC) and cost-optimized cloud operations. Notably, he drove a 30% acceleration in feature delivery at Alerzo and architected PCI-compliant, real-time payment infrastructure at Shago Payments, showing a rare blend of product-facing delivery and backend systems rigor.
