Freelancer profile translated to English.

Description

Ruby on Rails developer for over 15 years, I help companies design, improve, and develop custom business applications: SaaS, ERP, CRM, MVP, ...

I intervene in particular on:

- Design, architecture, and development of applications

- Taking over, refactoring, and improving the quality of existing applications

- Technical leadership and coaching of development teams

- Implementation of best practices: TDD, CI/CD, code reviews, ...

- Technical and functional scoping: needs definition, MVP, backlog prioritization

With over 10 years of consulting experience, I support my clients long-term, from design to production and continuous product evolution.

Beyond development, I also assist my clients with the strategic and functional aspects of their projects: defining needs, identifying high-value features, prioritizing the backlog, etc.

As a backend specialist, I master the entire product lifecycle: architecture, development, testing (TDD), code quality, CI/CD, deployment, maintenance, and optimization.

I can intervene:

- On a fixed-price basis (MVP, product build)

- On a time and materials basis (technical reinforcement / lead dev)

I also leverage a network of freelancers (design, mobile, product) to quickly assemble a team tailored to the project.

Nerya develops software in the field of industrial maintenance and safety.

When I joined, application development was entirely outsourced, with a provider struggling with the growing complexity of projects and critical business needs.

I led the complete re-internalization of development and provided technical leadership for the teams, with responsibilities including:
- Recruiting, onboarding, and coaching internal and external developers
- Defining and implementing development standards and best practices
- Deploying a GitLab platform and CI/CD pipelines
- Upgrading Rails versions and various dependencies
- Repairing and stabilizing the test suite
- Implementing monitoring and error tracking solutions
- Stabilizing and continuously improving the codebase
- Participating in design workshops, and writing and estimating user stories

Development is now fully internalized, structured, and sustainable. I continuously act as a technical expert, ensuring technical quality, team skill development, and architectural coherence.

As the application grew and succeeded, I supported its technical evolution, architecture, and team organization to ensure its scalability and reliability.

Following several funding rounds totaling several million euros, I participated in the internalization of the technical team, which now handles all development.
