Professional profile

End-to-end engineering ownership

I have worked in web development since 2014 and independently since 2018, covering frontend engineering, backend systems, databases, APIs, infrastructure, deployments and long-term production support.

My work goes beyond implementing interfaces. I can take a business requirement, design the technical approach, build the application, integrate external services, deploy it and continue maintaining the system after launch.

I am equally comfortable working on existing production systems: debugging, feature development, performance optimisation, migrations, workflow automation and modernisation of codebases that have outgrown their original architecture.

Technologies used in production work

I prefer describing technologies I actively use rather than presenting an exhaustive keyword list. The architecture always follows the problem being solved.

Production work

Evidence through systems that actually run

Seniority is better demonstrated through ownership and production systems than through a list of technologies.

Technical ownership

I work across the complete application lifecycle

I can own the technical lifecycle end to end or integrate into an existing engineering team where a specific area needs senior support.

Architecture

Application structure, data modelling, separation of concerns and technical decisions designed around maintainability and future change.

Frontend Engineering

React and Next.js interfaces, reusable components, rendering strategy, performance, technical UX and accessibility.

Backend Engineering

APIs, business logic, authentication, integrations, webhooks, server-side processes and data operations.

Databases

Relational modelling, queries, migrations and persistence using PostgreSQL, MySQL or SQLite depending on project requirements.

Production & Infrastructure

Docker, Linux, VPS infrastructure, deployments, service configuration, incident diagnosis and ongoing maintenance.

Product & Business Context

I translate operational requirements into software rather than treating engineering decisions as isolated technical exercises.

Availability

Ways I can work with a team or business

I work remotely from Spain with companies, founders and technical teams that need experienced engineering ownership.
