Backend Engineering

Senior backend engineering for broken, complex and production-critical systems.

I help software teams diagnose, repair and ship difficult backend work without adding long-term staffing overhead.

Laravel · PHP · .NET · APIs · Payments · PostgreSQL · Redis · Docker

When the easy part is already done.

CryptoPust is most useful when the problem is not “write another CRUD endpoint,” but figuring out why an existing system fails, behaves unpredictably, or cannot be trusted in production.

  • the application works until production
  • an AI-assisted codebase needs engineering review
  • a third-party integration behaves unpredictably
  • deployment or infrastructure is unstable
  • a backend issue is blocking delivery
  • a team needs senior backend capacity for a narrow problem

How I work

  1. 01

    Scope

    Understand the system and define the actual problem.

  2. 02

    Diagnose

    Inspect code, architecture and failure behavior.

  3. 03

    Implement & Test

    Make targeted changes and verify them.

  4. 04

    Handoff

    Deliver code, findings and clear technical notes.

Backend engineering without the ceremony.

I focus on backend systems, integrations, production reliability and technically difficult work. Modern AI-assisted tools may accelerate implementation, but architecture, technical judgment and final review remain human-led.
