NigeriaWhat I'm looking for
I am a Senior Software Engineer with over 15 years of experience delivering enterprise solutions across FinTech, Banking, Insurance, and Telecommunications. I design and implement scalable microservice architectures, digital loan platforms, and payment integrations that support high-volume transactions and strict compliance requirements.
My technical expertise spans Java, Python, Spring Boot, RESTful APIs, cloud platforms (AWS, GCP), containers (Docker, Kubernetes) and relational databases such as MySQL and PostgreSQL. I have a proven record of improving system reliability and throughput—examples include platforms supporting 1M+ transactions/month and messaging pipelines handling 500K+ events/day.
I continuously expand my skills in AI, machine learning, and prompt engineering while maintaining strong cross-functional collaboration, product delivery focus, and an emphasis on ethics and practical AI adoption. I seek to apply this blend of architecture, cloud, and emerging-AI experience to build robust, compliant, and innovative products.
