Weekly engineering engagement
Reserved capacity for existing software, recurring engineering needs or an ongoing workstream. Weekly availability is limited and confirmed before engagement.
Independent software engineering
Senior engineering for complex software systems.
I help software companies and engineering teams design, build and improve production systems—from backend architecture and integrations to cloud infrastructure and AI workflows.
Work directly with an experienced engineer who can take ownership of difficult technical work without requiring a separate delivery team.

01Where I fit into a team
Senior engineering capacity for work that needs ownership.
I work with founders, CTOs and engineering teams that need experienced hands-on capacity or someone to take ownership of a difficult technical workstream.
I can join an existing codebase, investigate unfamiliar systems, make architectural decisions and implement changes through to production. Engagements can be ongoing with reserved weekly capacity or structured around a defined project.

↗04Integrations & automation
Third-party APIs, data synchronization, background processing and recovery.
↗03Professional experience
Experience across real production systems.
I’m Serhii Cheredko, founder and principal software engineer at Absolyd. Since 2017, I’ve worked across SaaS platforms, insurance integrations, design products, booking systems and AI capabilities.
My production stack includes TypeScript, Node.js, Python, React, SQL and AWS. I work directly in the codebase and stay accountable for the decisions and delivery within the agreed scope.

Defined engineering project
A specific implementation, integration, migration or technical improvement with agreed deliverables, milestones and responsibilities.
05Continuity without lock-in
Direct responsibility, with your team in control.
Source code normally lives in a client-controlled repository. Important decisions, deployment instructions and recovery paths stay documented so another engineer can understand and operate the system.

Let’s discuss the engineering work.
If you need help with an existing system, a difficult technical problem or a defined implementation, send me a short description. A formal specification is not necessary.
