You will get your SaaS stabilized: bugs fixed, errors handled, deploys cleaned up
Project details
Your SaaS works... most of the time. Errors pile up, deploys are scary, and that one bug keeps coming back. You don't need a rewrite - you need a stabilization sprint.
WHAT I DO IN A SPRINT
1. AUDIT: I go through your codebase, error logs and deploy process, and deliver a prioritized list of what's actually broken vs. what can wait
2. FIX: I work through the priority list - crashes first, then data integrity, then the annoying stuff
3. HARDEN: error handling, input validation, sane logging so future bugs tell you where they are
4. DOCUMENT: what I changed, why, and what I'd tackle next
STACKS I WORK WITH DAILY
JavaScript/TypeScript, Python, Flutter, Cloudflare Workers/D1, Supabase/Postgres, Stripe, REST APIs.
YOU GET
Fixed and pushed code (PRs you can review), a written report, and a video walkthrough of everything changed. I work in branches - nothing merges without your approval. Your codebase stays yours.

Frequently asked questions
About David
Stripe & Supabase Expert - Webhooks, Subscriptions, Fast Fixes
Carino, Spain - 4:09 am local time
What I handle:
- Bug fixes: Flutter/Dart apps, Python scripts, JS/TS, REST APIs
- Backends: Cloudflare Workers, D1, Supabase, Stripe integrations
- Automation: web scrapers, data processing, API integrations, bots
- Trading tech: MQL4/MQL5 Expert Advisors and indicators (MT4/MT5)
How I work:
1. You describe the problem (repo access or code snippet helps)
2. I confirm scope and a fixed price - no hourly meters running
3. You get the fix + a short video showing it working
4. You approve when satisfied. That's it.
Working languages: English, Spanish, Galician. I'm also happy to handle all written communication in German, French, Italian, Portuguese or most other European languages - whatever is most comfortable for you.
I keep scope tight and communication fast (responses within the hour, European timezone). If I can't fix it, I tell you upfront - no wasted time.
