Alex P.
About this gig
Bugs blocking your Node.js, PHP or JavaScript project?
If your application:
- crashes or throws errors
- behaves unexpectedly
- works locally but fails in production
I will identify the real cause and fix it properly.
Professional Debugging Service
I provide professional debugging and bug fixing for:
- Node.js (Express, APIs, async issues, memory leaks)
- PHP (procedural, OOP, legacy code, APIs)
- JavaScript (frontend & backend logic, async bugs)
️ How I work (this is why clients trust me)
- Analyze your code and logs
- Reproduce the issue (when possible)
- Identify the root cause (not just symptoms)
- Apply a stable, production-safe fix
- Test the solution
- Explain what was wrong (optional)
️ No random fixes. No hacks.
IMPORTANT Please message me before ordering if:
- the bug is intermittent
- the project is large
- the issue happens only in production
Not sure which package fits your issue?

Full-stack engineer focused on backend systems and APIs.
I design and build reliable, scalable services for high-traffic platforms, with strong experience in real-time data processing, integrations, and backend architecture.
I favor clean, purpose-built code tailored to specific requirements over generic solutions, especially when performance, predictability, and long-term maintainability matter.
My main stack includes Node.js and PHP with relational and NoSQL databases on Linux environments. Frontend tasks are supported when required, with backend quality always the priority.
