Service details

Need a feature built, a bug fixed, or a backend system completed?

I help founders, startups, and small teams ship working web functionality fast, without unnecessary complexity.

I specialize in logic-heavy web development, not brochure websites. My work typically involves backend APIs, authentication systems, admin dashboards, integrations, and application workflows that power real products. If you already have a codebase and something is broken, incomplete, or blocking progress, I can step in and move it forward.

What I can help you with:

  • Backend APIs and business logic
  • Authentication and role-based access control
  • Admin panels and internal dashboards
  • Payment and third-party integrations
  • Fixing, refactoring, or extending existing codebases
  • Connecting frontend applications to stable backend services

I work best on clearly defined problems where speed and correctness matter. This includes adding new features, fixing bugs, completing half-built modules, or improving backend structure so your application is reliable and maintainable.

My typical stack includes Java and Spring Boot on the backend, JavaScript or TypeScript on the frontend, relational databases, and standard authentication mechanisms like JWT or OAuth. I focus on clean APIs, predictable behavior, and practical solutions that are easy to maintain after delivery.

I don’t take vague “build everything” requests. If you have a concrete requirement or a specific issue, we can define the scope quickly and get it done without wasted time.

  • If you need working functionality—not just a website—this offer is a good fit.

Special note from freelancer
I focus on clean, production-ready fixes and features. I analyze the issue first, propose the safest solution, and implement with minimal disruption to your existing codebase.
FAQs
What is included in this package?

One small bug fix or a clearly defined feature. Includes code changes and basic testing.

What is NOT included?

Large refactors, multi-feature modules, or unclear requirements. Those need a custom quote.

Do you work with existing codebases?

Yes. I work with existing backend or full-stack projects and follow your current architecture.

Will you deploy the changes?

Deployment is included only if access and setup are already available. Otherwise, I provide instructions.

What do you need to start?

Problem description, repo access (if needed), tech stack details, and expected behavior.
