About James

Self-entrepreneur and Full-Stack developer, studying for a Master's degree in Computer Science. After several internships and a fixed-term contract as an Assistant Engineer, I have structured a rigorous work method: clear scoping, clean development, testing, documentation, and usable delivery.

What I do

High-performance showcase websites and landing pages (responsive)

Business web applications, client areas, back-office / admin

REST APIs (authentication, payments, emails, webhooks)

Dashboards (KPIs, reporting)

Automation (scripts, scraping, ETL, report generation)

Bug fixing, maintenance, optimization (performance / stability)

My work method

Scoping: objective, constraints, scope, deliverables, deadlines

Execution plan: breakdown into steps + transparent estimation

Development: version control, regular progress updates

Quality: testing, basic security, performance, documentation

Delivery: deployment/patch + handover + initial support

What you get

A clean and maintainable deliverable (readable, structured code)

A clear explanation of what was done

Organized files / access (repository, procedures, backup if necessary)

Send your needs (objective, deadline, budget, constraints): I will respond with a simple plan and an estimate.
