Build your product

From product idea to production software.

Mobile and web product delivery using AI-assisted engineering, backed by 15 years of software experience.

Build something people can use.

I can take a product requirement, a Figma design or an existing application and turn it into a working mobile or web product.

I ship Android-first products and work across iOS and web when the project requires it. For iOS, I scope the work around the product and the team’s existing expertise.

From first feature to production

  • Android and mobile applications
  • Web applications and production-ready features
  • Backend/API components and integrations
  • Rapid prototypes with a clear path to production
  • Testing, debugging, deployment and handover

Have a design and need a working app quickly?

I can help you use AI-assisted development without losing engineering quality.

How we work

01

Define

Agree on the users, scope and acceptance criteria.

02

Implement

Work from the design, explore the repository and use AI to accelerate implementation.

03

Validate

Review code, test behaviour and integrations, and iterate against the design.

04

Ship

Deploy, verify the production behaviour and document the handover.

AI-assisted product delivery

Auchan Côte d’Ivoire

2026 · Freelance

From Figma to production, beyond my core stack.

An institutional website delivered across frontend, Ruby on Rails, PostgreSQL and production deployment, using Claude Code and MCP.

AI-assisted engineering

Faster implementation.
Engineering judgement stays.

I use AI as an engineering accelerator, not as a substitute for engineering judgement.

See the Auchan delivery →

I use Claude Code, MCP, Figma MCP and coding agents to explore codebases, turn designs into code, implement features, generate tests, investigate bugs and document decisions.

  • Generated code is reviewed.
  • Tests are required and outputs are validated.
  • Architecture and production responsibility stay with me.
  • AI suggestions can be changed or rejected.
