Solutions Architect · Distributed Systems

I turn ambiguous, high-stakes ideas into distributed systems that ship.

15+ years designing high-load, fault-tolerant platforms — owned end-to-end from architecture to production. 10+ systems live right now, delivered at the velocity and cost of a small team.

The differentiator

Architect-grade judgment at the velocity of a small team.

I design the system, decompose it into precise specs, then drive an AI-assisted delivery workflow — AI agents implement under my continuous review, test, and hardening. You get the taste and accountability of a senior architect with the throughput of a whole squad, and none of the agency overhead.

See how it works
  • One throat to choke A single accountable expert owns architecture through production — no hand-offs, no telephone game.
  • Parallel throughput 10+ production systems run in parallel today. The workflow scales output without diluting judgment.
  • Spec-first, not vibe-first Every build starts from a reviewed design and precise decomposition — measured twice, cut once.
  • Shipped & kept running Not slideware. Real systems in production with monitoring, rollback, and reliability baked in.

What I do

Services engineered for high-stakes builds.

Six ways I take you from ambiguous idea to a system that runs in production.

System Architecture & Design

Distributed, event-driven, real-time systems designed for high load and graceful failure.

  • Event-driven
  • CQRS
  • Fault-tolerance
  • Domain modeling

End-to-End Delivery AI-accelerated

From reviewed spec to production, driven by an AI-assisted workflow under my continuous review.

  • Spec-first
  • AI agents
  • Code review
  • Prod hardening

Integration & Data Platforms

Kafka/ESB backbones that sync dozens of systems in real time — one source of truth, everywhere.

  • Kafka
  • ESB
  • Real-time sync
  • Pipelines

Cross-Platform Product Build

One accountable owner for backend, iOS, Android and web — a coherent product, not stitched silos.

  • Backend
  • iOS · SwiftUI
  • Android · Compose
  • Web · PWA

AI & Automation

LLM toolchains, MCP tools, voice AI and agentic workflows that operate real infrastructure.

  • LLM
  • MCP
  • Voice AI
  • Agents

Cloud & Infrastructure

Production-grade AWS — compute, serverless, managed queues and databases — plus Kubernetes, CI/CD, observability and autoscaling. Architected to scale and heal itself.

  • AWS
  • EC2 · Lambda
  • SQS · RDS
  • Kubernetes
  • CI/CD

How I work

A disciplined pipeline. Measure twice, cut once.

Every engagement follows the same accountable path from first call to production.

  1. Request

    We map the ambiguous goal, constraints and stakes into a shared problem statement.

  2. Plan

    Architecture, decomposition and precise specs — reviewed and approved before a line is written.

  3. Build

    AI-accelerated implementation under my continuous review — fast, but never unsupervised.

  4. Verify

    Independent testing, security review and reliability checks against concrete pass/fail criteria.

  5. Ship

    Deployed to production with monitoring, rollback readiness and documentation as code.

About

One accountable expert — not an agency.

I'm Serge Kutin, a Solutions Architect with 15+ years designing and shipping distributed, high-load, fault-tolerant systems. I own the whole arc: architecture, decomposition, precise specs, implementation, verification and production operation — so nothing gets lost between roles.

My reach is deliberately full-stack: cloud backend, native iOS and Android, desktop and AI — and I take it all the way to production myself, deploying scalable, production-grade infrastructure on AWS and Kubernetes. Paired with an AI-assisted delivery workflow, that breadth lets a single hand deliver what usually needs a team — with tighter judgment and a straight line of accountability.
