From interfaceto infrastructure.

Full Stack & DevOps Engineer

I build products and the engineering systems behind them — from polished interfaces and APIs to testing, AI-assisted workflows, CI/CD, and production.

Product → engineering system → reliable delivery

01 Engineering footprint

  1. 01

    Product Engineering

    Interfaces, APIs, data models, and the cross-stack decisions that turn requirements into a coherent product.

    React · Next.js · Node.js · NestJS · PostgreSQL
  2. 02

    Engineering Systems

    Repository architecture, explicit contracts, testing strategy, developer tooling, and AI-assisted workflows.

    Standards · Tooling · Quality gates · Agent guidance

    Delivery & Reliability

    Build, release, deployment, and validation systems designed to make shipping repeatable instead of fragile.

    Docker · CI/CD · AWS · Release automation
  4. 04

    Design Engineering

    Component systems, visual standards, accessibility, and frontend architecture that keep interfaces coherent.

    Design systems · Responsive UI · Frontend architecture
02Selected work

Systems with a point of view.

Two flagship stories show the same instinct in different contexts: find the source of drift, formalize the better path, and make quality repeatable.

01

Designome

AI-assisted engineering · Personal project

First executable vertical slice

Turning UI screenshots into evidence-backed Design DNA for coding agents.

Designome extracts the reusable design grammar behind screenshots, represents uncertainty explicitly, and installs an accepted design contract into a target project so future UI generation can stay coherent.

Observed

Directly visible in supplied evidence.

Inferred

Derived from visible patterns and relationships.

A design decision offered for explicit acceptance.

Unknown

Not provable from static screenshots.

Document AI

Product engineering · Engineering systems · DevOps

My Talents Academy · 2025–2026

Engineering the product—and the system used to build it reliably.

A complex multi-tenant document platform where I shaped cross-stack features alongside repository architecture, frontend standards, AI-assisted workflows, testing strategy, release automation, and deployment validation.

Connected commerce

Ameublement Cameroun

A public catalogue, operational back office, shared versioned API, and bilingual Android experience built around one product source of truth.

End-to-end web, backend, data, and mobile product engineering

Decision and survey operations

Monark Suite

Related B2B products for structured decision workflows and confidential survey campaigns, presented together to show the broader operational system.

Booking platform

Mapan

A high-traffic booking product with secure APIs, asynchronous workflows, and modular React surfaces designed to evolve with the operation.

Frontend leadership and cross-stack product engineering
03How I build

A repeatable way to reduce friction.

  1. 01

    Observe

    Find the recurring friction, drift, or decision that keeps costing the team.

  2. 02

    Structure

    Turn the pattern into explicit constraints, contracts, and ownership.

  3. 03

    Build

    Encode the better path in architecture, components, tools, or automation.

  4. 04

    Validate

    Test the system against real behavior, not only the intended design.

04Experience

From early leverage to durable engineering systems.

Roles are not given equal visual weight. The longest, most relevant experiences carry the deeper engineering story.

06About

I turn recurring engineering friction into reusable systems.

I tend to notice where implementation repeatedly drifts, where a process depends too much on memory, or where a tool can remove friction. My instinct is to make the better path explicit through rules, reusable components, automation, or infrastructure.

That is why my work often spans product engineering, frontend systems, backend APIs, developer workflows, DevOps, and delivery. I remain hands-on across the stack while improving the environment in which the next feature will be built.
