Informazioni su questo servizio
Is your backend breaking in production? Let a senior engineer fix it properly, not patch it.
I am a Senior Backend Engineer with 10 plus years shipping Nodejs, NestJS, and Laravel in production. I find the root cause and fix it cleanly.
What I fix:
- Nodejs, NestJS, Express APIs that crash, leak memory, or throw silent errors
- Slow APIs, memory leaks, CPU spikes, connection pool exhaustion
- Laravel and PHP issues like N plus 1 queries, failing jobs, auth breaks, 500 errors
- Slow PostgreSQL or MySQL queries, missing indexes, deadlocks
- AWS Lambda timeouts, SQS SNS misfires, API Gateway 502s
- Stripe webhook failures, duplicate charges, subscription sync issues
- Broken BullMQ or RabbitMQ queues, stuck jobs, retry loops
What you get:
- Root cause diagnosis, not just a surface patch
- Clean tested fix with a short written summary
- Prevention notes so it does not happen again
- Clear English communication throughout
Recent work includes a multi tenant SaaS processing 1000 plus daily orders and a high concurrency real time betting engine.
Message me with your bug and stack. I will confirm the right package.
Reliable backends. No drama. Message me.

FAQ
How do I know if my bug is Basic, Standard, or Premium?
Send me a message with the error, your stack, and what you have already tried. I will tell you honestly which tier fits. If I misjudge once we start, I absorb the difference.
Can you fix bugs on live production sites?
Yes. I work carefully on production — staging first when possible, atomic deploys, rollback plan ready. For live incidents, use the Premium package for 24-hour priority response.
Which stacks do you support?
NestJS 10 plus, Nodejs 20 and 22, Express, Laravel 10 and 11, PHP 8 plus. Also comfortable with legacy Laravel 5 plus and older Node codebases. PostgreSQL, MySQL, MongoDB, Redis, AWS, Docker.
Do you provide a report of what you changed?
Yes. Every delivery includes a short written summary — what was broken, why, what I changed, and how to prevent it next time. You keep the full git diff.
Do you offer any guarantees?
Yes. If the same bug recurs within 7 days of delivery, I fix it free. Unlimited revisions until the fix is solid.
Will you sign an NDA?
Yes. Happy to sign a standard NDA before you share any code or credentials. Just mention it in your first message.
What do you need from me to start?
A short bug description, access to the repo (GitHub, GitLab, Bitbucket), and staging or local setup instructions. If access setup takes effort, I can guide you on a quick call.
