Profile

Full-stack engineer who takes ambiguous features from a blank page to a shipped system: scoping the problem, proposing the architecture, aligning the team, and delivering it. Comfortable across the stack (Spring Boot, NestJS, Kotlin, Vue/Nuxt, React), with practical DDD and service-boundary experience from production feature work and a hands-on monolith-to-microservices migration exercise. I mentor teammates directly, work closely with Product Owners, and have caught data-correctness issues before they reached production. No production .NET Core or React Native yet, but I pick up stacks fast: my background already spans Java, Kotlin, TypeScript, and Rust.

Work Experience

AmalitechNov 2025 – Present
Backend Engineer – NSP Takoradi, Ghana
  • Owned the Bonus Period feature end to end from an open-ended ask: scoped it into a lifecycle state machine (upcoming, active, computing, finance review, finalized, closed) and presented it to align the team on a new shared computation model.
  • Published computed bonus data to Kafka for consumption by Amalitech's payroll service, restructuring the payload to match their spec and coordinating directly with them on the integration contract.
  • Proactively flagged access-control and architecture risks to the Product Owner ahead of incidents, and caught a data-correctness bug (wrong computation cutoff date) before it reached production.
  • Mentored teammates directly: set up mock-server backend integration for one colleague, walked another through scoring/configuration internals, and paired on frontend pipeline fixes.
  • Architected JWT/RSA authentication with SSO and RBAC across six roles; enforced data integrity via PostgreSQL triggers, fixed N+1 GraphQL queries with batch fetching, and kept 70%+ test coverage (JaCoCo, Hurl E2E) with rate limiting as a production-grade standard.
Zomujo FoundationOct 2023 – Feb 2026
Backend Engineer – Freelance (Live Url)Remote, Ghana
  • 2.5+ years progressively owning backend systems for a health-tech platform, from intern to freelance engineer: cloud file storage, verification flows, PDF generation, and real-time notifications (SSE, WebSocket/Socket.io) for time-sensitive appointment and consultation state changes.
  • Led an EMR migration from TSOA to NestJS/Prisma with zero data loss, restructuring serialized JSON columns (labs, radiology, diagnosis/prescription) while keeping the API surface backward compatible for existing clients.

Projects

Food Delivery Platform: Microservices Migration (AmaliTech Training Academy)
2026
  • Completed a hands-on architecture lab decomposing a Spring Boot monolith into four bounded-context services (Customer, Restaurant, Order, Delivery) with DTO/event contracts, service discovery (Eureka), and an API gateway with edge JWT auth, containerized via Docker Compose.
  • Implemented event-driven communication with RabbitMQ (topic exchange, dead-letter queues, retry policy) and fault tolerance with Resilience4j circuit breakers and fallbacks.
Cyale Website | Live URL | GitHub
  • Designed and delivered a full-stack nonprofit website end to end, live in production (NuxtJs/Vue 3/TypeScript, Prisma, PostgreSQL, Vercel): member auth, an impact showcase, event announcements, and a donation flow, owned from schema through UI.
Adzesua: Multi-Tenant School Management Platform
2026
  • Building a multi-tenant Spring Boot/Kotlin backend (tenant onboarding, fee structures, installment billing, Paystack payments) with per-tenant branding, Google OAuth2, and structured request-lifecycle logging.
