Let's Talk

I'm Sergey

I work with a practical, engineering-driven approach — building systems that are clear, stable & operable over time.

My focus is on clarity and ownership:
code that can be understood and infra that can be controlled, enabling teams to continue development safely.

Engineering for Production

Working on production-grade systems. 
Infra, Backend, Applied AI/LLM and DevOps as a single unit, with responsibility for stability and reliable behavior in production.

Scale & Control

Stabilization of production systems —
devOps, observability & cost control, including re-architecture where required.

Backend & Architecture

Databases, High-load APIs, AI/LLM integrations, and infrastructure designed for ownership at scale.

AI in Production

Applied AI as part of backend systems — from DB to RAG pipelines — with a strong focus on production stability.

Web Apps & Platforms

Designing backend & cloud for high-impact web platforms — built to meet required scale.
End-to-end.

Selected Project Engagements

Live System · High Traffic (millions daily requests)
Project required precision under high traffic in live systems.
Stabilization, monitoring, optimization, and deployment in production.

AI as a System Component, Not a Patch
Hardening AI infrastructure & backend —
RAG pipelines, workflows, logic, observability, and controlled behavior.

Vibe Coding → Production (AWS)
Migration of Replit app to AWS (self host).
Taking ownership of the code and adapting to production readiness.

Reinforcing CTO
Ongoing alongside CTO of tech-oriented company.
Engaging as an architectural force multiplier — closing knowledge and time gaps.
Restoring Ownership
System that grew organically and lost control in production.
Deep analysis and recovery of tacit knowledge — enabling safe & fast maintenance.
