Back-end engineering
& AI integration
for teams that ship.

I'm Mykhailo Sydoruk — a .NET engineer with 15+ years in IT and 4+ years building production C#/.NET 10 back-ends. I help small and mid-sized businesses automate work with AI agents, integrate LLMs into existing systems, and ship software faster using AI-native tooling.

Engineer first. AI pragmatist second.

I write back-ends that hold up under load, then layer AI where it earns its place — agents, LLM orchestration, deterministic compute pipelines, and internal tooling that removes busywork.

# Three things, in plain words:
→ build AI-powered features on top of real .NET back-ends
→ automate back-office work for SMBs with agents & integrations
→ advise devs/teams on AI-native workflows that actually ship

Four ways I can help.

Fixed scopes, advisory retainers, or embedded engagements. I work solo or alongside your existing engineers.

/ 01
SMB focus

AI automation for SMBs

Remove the 20 % of manual work eating 80 % of your team's time. Internal tools, agent workflows, LLM-powered document and data pipelines — wired into the systems you already use.

  • Back-office & ops automation
  • Document intake, extraction, routing
  • Inbox / ticket / CRM agents
  • Reporting & summarisation pipelines
/ 02
enterprise

AI integration into business

Pragmatic AI adoption for any industry. We map where LLMs genuinely earn their keep, design the architecture, and ship a working pilot — not a slide deck.

  • Use-case discovery & ROI sizing
  • LLM + tool orchestration architecture
  • Deterministic compute layers for AI output
  • Security, cost & guardrails review
/ 03
for developers

Consulting for dev teams

How do you actually ship with AI on your side? Pairing sessions, code reviews, and tooling setup that move your team from copy-pasting prompts to structured, repeatable delivery.

  • AI-native workflow setup
  • Prompt & tool-use patterns
  • .NET architecture & code review
  • Legacy → modern .NET migrations
/ 04
build

AI-accelerated development

Custom back-ends, APIs, and AI-powered features — built fast using AI-native development practices without cutting corners on tests, structure, or maintainability.

  • ASP.NET Core services & APIs
  • LLM-powered product features
  • Agent & tool integrations
  • Proof-of-concepts in days, not months

The tools I reach for.

Opinionated, boring where it matters, sharp where it counts.

Short feedback loops. Boring infrastructure. Real output.

Every engagement starts with a 30-minute intro call. No decks, no discovery theatre.

01 / scope

Intro call & fit check

30 minutes, free. We look at the problem, what you've tried, and whether I'm the right person.

02 / design

Map & prototype

Short written plan, architecture sketch, and a working spike where useful — usually within a week.

03 / ship

Build in the open

Pushed code, visible progress, weekly demos. AI-assisted where it helps, hand-written where it matters.

04 / handoff

Handoff & support

Docs, tests, runbook. Optional retainer for evolution and on-call during rollout.

Selected experience.

The last decade, in short.
