What I'm looking for

I'm looking to build scalable backend systems and intelligent products, applying Java, Spring Boot, microservices, event-driven architecture, and AI to solve meaningful financial-services or product challenges.

At GIKTEK, I build enterprise backend systems for banking and financial services, delivering secure, scalable digital solutions with Java, Spring Boot, microservices, and event-driven architecture.

For Standard Bank South Africa, I delivered supplier-finance microservices spanning invoice submission, funding, and settlement. I also built a configurable rules engine with 20+ validation rules and used AWS SQS for reliable invoice lifecycle events.

For Stanbic Bank Ghana and Stanbic Bank Kenya, I built digital business onboarding, KYB, and customer compliance integrations. My work includes secure REST APIs, onboarding orchestration, internal banking integrations, and asynchronous compliance screening workflows with NICE Actimize.

I also build AI-enabled products, including ShipDaily and PostMind. I've integrated Claude AI, Groq LLM, Firebase, Telegram, and Twitter/X APIs to create intelligent feedback and content-publishing workflows.
