At Azguard Technology, I led backend development across the microservices behind Yuzee, an education platform connecting learners with institutions, courses, and offers. I developed authentication, multi-currency transfers, offer-management APIs, and personalized learning paths.

On Yuzee’s AI systems, I built an LLM-driven learning pathway engine and a prompt-to-audio pipeline for course narration, summaries, and accessibility. I also developed multimodal content ingestion and retrieval-augmented generation patterns with Spring AI.

I built a WhatsApp API CRM supporting real-time, two-way messaging for multiple small businesses. I developed webhook handlers and added scheduled reminders, follow-ups, and template campaigns.

In contract work at MNGP, I designed authentication with Spring Security and JWT, implemented mobile two-factor authentication, and integrated Flutterwave payments. Earlier, I built a social engagement platform and a real-time vehicle tracking and fleet management system.
