Hi, I'm Andrew Mintah

Senior Engineer | Creative Problem Solver

About Me

Senior Backend Engineer with 6+ years' experience designing and delivering distributed systems, high-scale APIs and event-driven architectures within financial services. Strong track record of building cloud-native platforms, improving system reliability, and collaborating cross-functionally to deliver impactful product features. Deep expertise in large-scale transactional systems using technologies like Java, Kafka, AWS, Terraform and many others. Passionate about building resilient services, simplifying complex systems, and delivering high-quality engineering outcomes in regulated environments.

When I'm not coding, you'll find me exploring new technologies, working on side projects or watching football. I'm always eager to connect with fellow engineers and discuss innovative ideas in software development and architecture.
