Your developer is asleep.
Production isn’t.
Senior software engineering on demand for production incidents, urgent bugs, broken deployments and technical problems that cannot wait until tomorrow.

Coverage 06:00–00:00 CET
Production is down
Errors, outages, broken critical paths and systems that need senior triage now.
The deploy went wrong
Rollback, hotfix, configuration, environment and release failures.
Payments or integrations broke
Stripe, webhooks, APIs, authentication, queues and third-party failures.
Your team is stuck
Senior debugging, architecture and a second pair of eyes on the hard problem.
A launch cannot slip
Reserved engineering coverage before, during and after go-live.
You need an escalation engineer
Pre-onboard me to your system before the next incident.
Most developers have core working hours.
I have core non-working hours.
My normal coverage is 06:00–00:00 Central European time. Between midnight and 06:00, I take genuine wake-up emergencies at a premium rate. If your issue can wait until tomorrow, do not pay emergency pricing.
Core non-working hours: 00:00–06:00 CET
Built systems people actually depend on.
I have spent 11+ years building and operating software people actually depend on: payment infrastructure, national customs systems, credit-data platforms, high-throughput network services and production e-commerce. Today I work AI-native — Claude Code, MCP servers, automated review and test loops — without dropping the engineering discipline: architecture, tests, observability and safe rollout.
- Direct access to the engineer doing the work.
- Production experience across .NET, TypeScript/React/Node, C++20, data and infrastructure.
- No ticket queue and no junior first-line filter.
- I will say no quickly when the stack or risk is outside what I can responsibly own.
11+ years
Production software engineering.
1M+ requests/day
API throughput shipped in payments infrastructure.
10k+ miners
High-throughput C++20 backend serving users across 5+ continents.
30% faster
Publicly stated customs-processing improvement.
2,300+ commits
Across four production codebases in 14 months, solo.
Triage. Stabilize. Repair. Verify. Prevent.
- 01
Tell me what broke. Send impact, start time, recent changes, stack and safe error/log context.
- 02
I confirm fit and urgency. If I cannot responsibly help, I say so before you waste time.
- 03
We establish safe access. Temporary credentials and least privilege are preferred.
- 04
Triage first. I identify the failure mode, stabilize the system where possible and explain the next move.
- 05
Fix or mitigate. I make the smallest safe change that restores service, then verify it.
- 06
You get a clean handoff: what happened, what changed and what should be prevented next.
Transparent rates.
Emergency work costs more because immediate availability has a cost.
