Work Experience

AI Software Engineer at Turing

January 5, 2025 - December 20, 2025

I built scalable Python pipelines for large-scale LLM evaluation across 500K+ prompts, designing structured JSON schemas and automated frameworks for consistency, accuracy, and reliability testing. I also created high-quality training datasets through advanced data parsing and worked closely with researchers to integrate human feedback loops to improve model alignment.

Senior Full Stack Engineer at Nebula

May 1, 2023 - December 20, 2024

I architected and maintained high-performance databases, optimizing queries for scalability, and worked closely with designers, product managers, and engineers to deliver impactful features. I introduced Zustand for state management, reducing frontend state complexity by 30%, enforced strict CI quality gates by eliminating code warnings and blocking faulty PRs, and partnered with product and design teams to ship AI-powered recruitment features that improved candidate–job matching.

Senior Full Stack Engineer at Akadenia

February 1, 2022 - May 31, 2023

I worked closely with the CTO to improve user experience across products by resolving performance bottlenecks and modernizing UIs. I built a Shopify admin app that helped support teams handle 30% more daily requests, strengthened application and data security through industry best practices, and reduced AWS costs by over 20% by migrating to S3 and serverless services. I also supported team growth by conducting technical interviews for engineering candidates.

Full Stack Engineer at Nsano Fintech

March 1, 2020 - March 3, 2022

I independently developed a fraud detection platform that blocked fraudulent activity and saved approximately $120K, and built a full-stack reconciliation engine to detect transaction errors and generate automated reports. I also created USSD applications and large-scale banking solutions used across Africa, while mentoring new interns and advocating for AI adoption in fintech, including piloting spending-pattern models.
