SaaS Rescue

SaaS rescue for products under real pressure

I help teams clean up fragile systems, reduce technical risk, and get through migrations, incidents, and messy handoffs without making the codebase worse.

When to bring me in

  • A previous developer left things half-working and nobody fully trusts the current system
  • The product is live, but every change feels risky, slow, or harder than it should be
  • A migration is blocked, fragile, or too important to rush
  • Auth, data, or infrastructure issues keep resurfacing without a clear root cause
  • The codebase grew fast and now delivery keeps getting dragged down by hidden complexity
  • You need someone who can diagnose, decide, and implement without creating more chaos

What I actually do

  • Plan and execute high-risk migrations with rollback safety, data integrity, and maintainability in mind
  • Isolate production issues across auth, data flow, infrastructure, and system boundaries
  • Stabilize fragile codebases before launch, handoff, or the next growth step
  • Clean up backend and API layers where ownership, reliability, or system behavior is no longer clear
  • Reduce infrastructure waste and operational drag without pushing complexity somewhere else
  • Replace brittle prototype foundations with production-ready systems that can survive real use

Selected rescue work

01 · Apr 2026

MeetYourMind

Migrated a live system from Lovable to Supabase – 9,778 rows across 27 tables, bcrypt password hashes preserved, zero data loss. The hard part was not moving the data. It was making the migration safe, reversible where possible, and maintainable for whoever touched it next.

Three Degrees

Diagnosed a GoTrue auth failure that had locked 1,643 users out of the product. Traced the failure to the actual system boundary instead of the surface symptom, restored access, and gave the team a clearer mental model of what had broken.

W3YZ Teknoloji

Recovered and stabilized infrastructure under live-event pressure during Dubai Festival operations, then reworked parts of the architecture to cut hosting costs by 45% – about $10,800 per year – without making the system less reliable.

More examples are on the work page, but these three show the kind of rescue work I get pulled into most often.

He goes beyond what you ask him to do and if there is a problem it’s sorted out quickly. He will be on my list to hire again.

How I work

I don’t start by rewriting everything. I start by figuring out where the real risk is.

  1. P/01Isolate the actual failure, not just the loudest symptom.
  2. P/02Reduce risk before adding complexity.
  3. P/03Make important changes reversible where possible.
  4. P/04Leave the system easier for the next person to understand and extend.

What working together looks like

Some teams need a second pair of senior eyes. Some need someone to take ownership and get the fix through. Usually it looks like one of these.

Mode 01

Technical diagnostic

A short investigation to identify the real failure points, risks, and likely path forward.

Mode 02

Fixed-scope rescue

A focused engagement to handle something concrete: migration, auth recovery, production issue, infra cleanup, or stabilization before launch.

Mode 03

Stabilization sprint

Embedded work over a short window to clean up the system, remove blockers, and make shipping safer again.

Mode 04

Technical partner support

Ongoing senior help across architecture, debugging, implementation, and decision-making when the product is moving but the system needs stronger hands.

Who this is for

  • Founders with a live product that has become fragile, messy, or risky to change
  • Teams inheriting a codebase they did not design and do not fully trust yet
  • Startups heading into a migration, launch, or handoff where mistakes are expensive
  • Product teams that need senior technical judgment, not just more implementation capacity
  • Teams that want the fix to hold up in production, not just pass for done

What I won’t do

  • Cosmetic rewrites with no real problem behind them
  • Speed-only work where reliability, data safety, or maintainability do not matter
  • Vague open-ended scopes without a decision-maker or clear ownership
  • Endless reactive support that treats symptoms but never fixes the underlying system
  • “Just make it work” requests where nobody wants to look at the actual risk

If the product feels fragile, blocked, or harder to change than it should be, send me the details

A short note, stack summary, or messy handoff document is enough to start. I’m especially useful when the issue is already real, the context is messy, and the fix needs to hold up after I leave.
