At PICAby BeauvisionAssociates, I developed RESTful APIs for diagnostic assessments and report generation, and implemented billing and transaction workflows with third-party payment providers. I also used Redis caching and background jobs to optimize high-traffic operations.
At Luna Top-up, I worked on a fintech bills payment platform supporting airtime, data, utilities, and VAS transactions. I built asynchronous task pipelines with Redis and Bullmq for payment execution, retries, and reconciliation, and implemented idempotent workflows to prevent duplicate charges.
At SympsLab – QuickAid Technologies, I engineered and maintained a Retrieval-Augmented Generation pipeline for personalized, context-aware emotional support. I integrated and optimized LLMs for report and symptom classification, and developed Express services with websockets for inference requests and continuous data capture.
