Go Backend Development

I build backend systems in Go — APIs, services and daemons that are fast, lean on resources and easy to run. Especially good for workers, data processing and long-running services.

I'm a backend developer with 10+ years of experience across PHP, Go, MySQL and Elasticsearch. Recent work includes Cenoskop (30M+ products daily), Niftycent (US price intelligence), and facha.sk (Go backend). I build, fix and optimize backend systems that handle real data and real traffic.

What I Can Help With

Build backend APIs, services and daemons in Go.

Typical Problems

new Go API needed background workers/daemons data processing services integrations Go performance tuning

Relevant Experience

Built facha.sk (facha.sk) in Go — a job and services marketplace with API, matching logic and deployment. Also built remotedaemon.com (remote security scanner) and various data processing services.

What Is Included

API design and implementation
worker/daemon implementation
database integration
third-party integration
tests and logging
deployment support

How It Works

We agree on scope, build in increments with your feedback, and hand over tested, documented Go code. Hourly rate €60, with fixed estimates for well-scoped work.

Frequently Asked Questions

When is Go the right choice?

For throughput-bound workers, data processing, and long-running daemons where PHP's per-request model or memory footprint is the constraint.
