Software Engineer with 4+ years in full-stack development and microservices, delivering high-concurrency platforms and workflow automation.
What I'm looking for
I’m a Software Engineer with 4+ years of experience in full-stack development and microservices. I focus on building systems that stay fast under load, while keeping delivery timelines tight through automation.
At Turntabl Ghana Ltd (Sep 2022 - Present), I architected a TikTok-style Flutter mobile app backed by Spring Boot and NestJS microservices. I built high-concurrency video streaming and real-time chat experiences, turning complex requirements into reliable features.
I’ve also delivered automation and platform capabilities across multiple domains. I engineered a Python solution for Active Directory migrations, cutting estimated completion time by 50%, and built synthetic data tooling that generates data at 2ms/row with 80% similarity to real data.
Before that, I developed tooling as a Railway Engineering Intern at The Automation Group Ghana (Jun 2021 - Aug 2021), including a CLI for GSM modem management and a Golang/Python plugin to simplify PLC communication. I bring an engineering mindset to every project—clean integrations, strong backend testing, and practical tech choices.
