Technical debt is slowly killing your business ?

I help companies and CTOs implement a plan to solve technical debt.

My Process

1

Understand

Context is everything.

A shared mental model of where you are — and what's hurting most.

Before we touch your code, we talk to your team. We dig into your product goals, delivery pain points, team rituals, and architectural history — because tech debt doesn't live in isolation. It's shaped by the way you ship.

  • • Stakeholder interviews (tech, product, devs)
  • • Repo & architecture walkthroughs
  • • Onboarding and delivery friction mapping
2

Measure

You can't fix what you can't see.

I create a visual debt map and quantified baseline to track improvement.

We run a deep audit of your codebase, pipelines, and team processes. Using static analysis, CI/CD metrics, and developer interviews, we map the different types of debt and assess their impact on speed, quality, and risk.

  • • Code complexity & structure
  • • Test coverage & reliability
  • • Delivery metrics (cycle time, PR aging, rework rate)
  • • Tool-assisted debt scoring by component or module
3

Prioritize

Not all debt is created equal.

A plan you can defend to leadership — and execute without breaking delivery.

Together, we build a remediation roadmap focused on ROI — not perfection. We score each issue by velocity impact, business risk, and dev pain to guide where to invest (and where to leave it alone).

  • • Quick wins
  • • Strategic refactors
  • • Long-term modernizations
  • • Debt-to-feature cost alignment

Track

Because debt is never really "done."

A self-correcting system. Cleaner code, less friction, and devs who stay in flow.

We install dashboards, git hooks, and PR tooling to keep debt visible and manageable inside your workflow. No more forgetting — or fighting for time to clean up.

  • • CI-based debt monitoring
  • • PR-level feedback and risk reports
  • • Monthly debt snapshots
  • • Custom dashboards by team or area
