Hey, I’m Samuel, an Experienced Full Stack Software Engineer specializing in Web Development. I build scalable, production-grade systems from backend to frontend. My core focus is on Node.js/TypeScript for robust backend architecture and React/Next.js for modern, high-performing user interfaces.   I have proven experience developing end-to-end solutions across fintech, AI/ML, and critical healthcare platforms.

I am currently engineering the resilient backend for an upcoming healthcare startup, Kovana Care, utilizing a high-performance stack (NestJS, TypeScript, Node.js, and Prisma). I designed the scalable monorepo structure (Turborepo/PNPM) to efficiently manage independent services like the Patient and Doctor APIs. I utilize Redis for crucial caching and asynchronous job processing (via BullMQ) to ensure fast responsiveness and handle high loads. My implementations feature secure JWT authentication, full user lifecycle management, and critical integrations like Twilio (SMS) and Nodemailer (Email).

As a backend engineer of an AI/ML startup, Nexus Botix, I was directly responsible for architecting and implementing key fintech infrastructure. I integrated Flutterwave for seamless and secure payment experiences, demonstrating an ability to translate complex business requirements into reliable production code.

I implemented a real-time notification pipeline for Kovana Care using EventEmitter, RxJS, and SSE (Server-Sent Events) for live updates across the platform. I also introduced a modular architecture and moved the backend to a Turborepo monorepo for the two backend applications: Doctors & Patients.

As an active member of the open-source community, I've collaborated on various projects to improve code quality, fix bugs, and add new features. This experience demonstrates my ability to integrate into existing codebases, work with diverse teams, and adhere to project standards—all crucial skills for a successful engineering environment.
