I build production systems where downtime is not an option.

Payments. Health platforms. Bank-grade messaging. Now leading 8 engineers from Cameroon to Switzerland.

Full Stack engineer with 7 years shipping production-grade web and mobile systems where reliability is non-negotiable. Expertise across the Angular / Laravel / Spring Boot ecosystem, event-driven architectures (Kafka), DevOps (Docker, Kubernetes, CI/CD), and payment integrations. Currently Senior Full Stack Developer at KimboCare (Switzerland), leading a team of 8 — over 30 developers managed across my career. Co-author of a peer-reviewed paper in software engineering.

AI Engineering.

I build AI features that ship — not demos. At KimboCare, I design and run production AI: an OCR pipeline for automated document extraction and an LLM-powered assistant coupled to the app, guiding users and simplifying their journeys.

LLMs & Generative AI

Transformer architectures, prompt engineering, foundation-model APIs.

Tech for SMEs, NGOs and education in rural areas

Africa Systems

Full Stack Developer · Odoo & Native Android

  • Built custom Odoo modules for SMEs and NGOs operating in underserved zones — improved data management across multiple field organizations.
  • Designed an Odoo ↔ ODK Aggregate interoperability layer — cut field-data processing time by ~40%.
  • Shipped offline-first native Android apps used by 500+ users in rural areas (low connectivity, deferred sync, data robustness).
  • Sekoo (Covid-19 period): mobile + web LMS platform for private training institutions, built on Odoo 12 → 14 — kept training continuity during lockdowns.
  • Architected and integrated REST services with strict reliability and performance constraints; engineered solutions adapted to terrain realities.

On-chain. Proof of care.

What started as decentralized-execution research is now production infrastructure. At KimboCare we use blockchain to make the medical record tamper-proof and auditable — an immutable, transparent care history and cryptographic proof-of-care for every beneficiary.

Applied at KimboCare

Smart Contracts

On-chain logic for proof-of-care attestations, access control, and auditable state transitions.

Hyperledger Fabric

Permissioned ledger for the medical record — private channels, endorsement policies, verifiable audit trail.

Polygon & Ethereum

Public-chain anchoring for immutability and transparency, with low-cost settlement on Polygon L2.

DApps & Traceability

Decentralized apps that trace a beneficiary's care end-to-end — immutable, transparent, verifiable.
