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.
Four ways I can help.
Fixed scopes, advisory retainers, or embedded engagements. I work solo or alongside your existing engineers.
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
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
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
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.
Intro call & fit check
30 minutes, free. We look at the problem, what you've tried, and whether I'm the right person.
Map & prototype
Short written plan, architecture sketch, and a working spike where useful — usually within a week.
Build in the open
Pushed code, visible progress, weekly demos. AI-assisted where it helps, hand-written where it matters.
Handoff & support
Docs, tests, runbook. Optional retainer for evolution and on-call during rollout.
Selected experience.
The last decade, in short.
Migrating backend services from .NET Framework to .NET 10. Designing modules for an IoT platform over AWS SNS/SQS. Integrating DynamoDB and Redis for distributed workflows and caching. Back-end work on AI-powered features — LLM integrations, tool-based orchestration, data aggregation pipelines, and deterministic compute layers for AI-driven analytics.
Client support, investigating data issues, SQL reports and data exports. Bridge between devs and stakeholders. Requirement clarification and feature follow-up.
Coordinated websites and e-commerce platforms on OpenCart, Joomla/VirtueMart, PrestaShop. Direct client work, requirements, specs, basic QA, and team coordination.
Got a project, a problem,
or a half-formed idea?
The fastest way to reach me is email. A short paragraph describing the problem is enough to get started — I'll reply within 24 hours on business days.
