Software Engineer · Refactoring & Technical Debt

Your vibecode has proven itself.
It's time to make it pro.

You have an app that works, users, a business that runs… but technical debt is starting to cost you dearly in time, bugs, and sleepless nights. That's exactly where I come in.

Do you recognize yourself in this situation?

🐛

Bugs are multiplying

Every new feature breaks another one. The code has become too fragile to move fast.

🐢

Performance is degrading

The app is sluggish, pages load slowly, users are complaining. The MVP can no longer handle the load.

😰

Nobody understands the code

Even you struggle to find your way around it. Onboarding a new dev takes weeks.

💸

Debt is expensive

You spend more time putting out fires than building what truly matters.

What I concretely do

I take over legacy codebases, often poorly documented, and transform them into maintainable, performant, and scalable applications — without breaking everything, and above all, without rewriting it all from scratch.

01

Technical debt elimination

I methodically analyze, prioritize, and pay down accumulated debt to restore velocity — without service interruption.

02

Performance optimization

Concrete example: ×7 on the most-used pages of a Django ERP through advanced ORM usage and an adapted caching strategy.

03

Future-proof architecture

Setting up patterns and architectures that allow you to keep shipping fast and at lower cost in the months and years ahead.

04

Tests, CI/CD & best practices

Safety nets, continuous integration pipelines, monitoring: everything that allows you to ship with confidence and sleep soundly.

Choose your starting point

Every codebase is different. Whether you need a clear diagnosis or a complete transformation, there's an engagement that fits where you are right now.

🔍
Starter

Code Audit

A thorough read-through of your codebase. You get a prioritized report of the top issues, quick wins, and a clear roadmap — without touching a line of code.

  • Codebase review & mapping
  • Prioritized issues report
  • Actionable recommendations
  • 1-hour debrief call
🏗
Full engagement

Full Rewrite

When the codebase is beyond salvaging, I rebuild it from the ground up with a clean architecture — same features, zero legacy debt, ready to scale for years.

  • Everything in Targeted Refactor
  • New architecture design
  • Full rewrite with zero downtime plan
  • CI/CD pipeline & monitoring setup
  • Handover & knowledge transfer

* Timelines are estimates and may vary depending on project scale and complexity.

Transparent pricing

No hidden fees, no surprises. Pricing adapts to your situation — the offering you choose, the scale, and the complexity of your project all play a role.

~$500 / day

Base daily rate for most engagements. Final cost is scoped upfront based on your codebase size, complexity, and goals.

📉

Volume discount

Longer engagements come with a decreasing daily rate. The more weeks committed, the better the value — we both benefit from a sustained, focused collaboration.

🧩

Incremental delivery

For larger projects, work is split into incremental deliverables that each bring standalone value. You can stop at any point when the results are good enough — no obligation to go all the way, keeping cost firmly under control.

🎁

Free initial analysis

When you reach out, I do a quick analysis of your project at no charge — so you know exactly what you're dealing with before committing to anything.

What clients say

"Our Django backend was a nightmare — 4-second page loads, untestable spaghetti code. In 6 weeks, load times dropped to under 500ms and the team can finally ship without fear. Best investment we made this year."

Marcus T. CTO, logistics SaaS startup

"I handed over a codebase no developer wanted to touch. He came back three months later with clean architecture, full test coverage, and a CI pipeline. Our dev velocity literally doubled."

Sophie L. Founder, B2B SaaS platform

"We were about to rewrite everything from scratch — a 6-month project we couldn't afford. Instead, the refactor took 8 weeks, kept all our data intact, and the app is now faster and easier to extend."

Julien R. Product lead, internal ERP
