Project details
I connect your app to the other systems your business runs on, and make the connection survive real traffic.
Integrations are easy to demo and hard to keep alive. Tokens expire, the other side rate-limits you, a webhook arrives twice, the network drops mid-request. With 12+ years of .NET experience I build the boring parts that stop those things becoming your problem: retries with backoff, idempotency, dead-letter handling and logs you can actually read.
What you get:
• Integration with any REST, GraphQL, SOAP or webhook API
• OAuth2 and API-key auth handled properly, with token refresh
• Retries, backoff, idempotency and duplicate protection
• Scheduled or event-driven sync, with a clear error trail
• Data mapping between systems that disagree about everything
• Full source code and a handover call
Stack: C#, ASP.NET Core, Azure Functions, Service Bus and queues, SQL Server, Angular or React for any admin UI.
Typical work: CRM and ERP sync, payment and invoicing, shipping and logistics, email and messaging, internal system-to-system pipelines.
Tell me which systems you need connected and I will tell you which tier fits.

About Ivan
.NET Full Stack Developer | React | Angular | AI | .NET
Mykolaiv, Ukraine - 7:19 am local time
Hi, I'm Ivan. I help SaaS and enterprise teams ship AI that survives production — Azure OpenAI, AI agents, MCP servers and RAG pipelines — built on the .NET and Azure systems I've engineered for over a decade. Most "AI features" fail because they're demos bolted onto a codebase nobody hardened. As an AI integration developer who is also a full stack developer, I build the AI layer and the platform underneath it: auth, data, retrieval, cost control, monitoring, and a deployment you can actually maintain.
🤖 What I do as an AI Integration Developer
✔ AI integration into existing apps — Azure OpenAI, GPT models, function calling, structured output
✔ AI agent development — multi-step agents that call your real APIs and databases
✔ MCP server development — expose your systems as tools to Claude, Copilot and other AI clients
✔ RAG pipelines — document ingestion, chunking, embeddings, vector search, grounded answers
✔ AI-powered document processing — import, export, extraction, classification, summarization
✔ Chatbots and copilots embedded in SaaS dashboards, admin panels and internal tools
✔ AI cost, latency and quality control — caching, model routing, evaluation, guardrails
☁️ What I do as an Azure developer
✔ Azure App Services, Azure Functions, Service Bus, Key Vault, Blob Storage
✔ Azure OpenAI deployment, private networking, managed identity and secrets hygiene
✔ Azure DevOps and GitHub Actions CI/CD, Docker containers, infrastructure as code
✔ Cloud migration and cost optimization — on-prem to Azure, monolith to microservices
⚙️ What I do as a .NET full stack developer
✔ C# / ASP.NET Core backends, REST APIs and microservices — Clean Architecture, DDD, CQRS
✔ React and Angular front ends, TypeScript, NgRx, RxJS — dashboards, admin panels, SPAs
✔ SQL Server, PostgreSQL and MongoDB — schema design, query tuning, migrations
✔ SaaS platforms, B2B products, CRM and ERP systems, WPF desktop applications
✔ Rescuing slow, brittle or half-finished .NET systems — re-architecture and modernization
📊 Experience in numbers
✔ 12+ years as a .NET developer and Azure developer, now focused on AI integration
✔ 5 industries shipped in production: FinTech, healthcare, banking, automotive, IoT
✔ 10 portfolio projects — enterprise platforms, SaaS products and internal tools
✔ Full product ownership on every one — architecture through production deployment
🧩 AI, Azure and .NET services
• AI integration and Azure OpenAI development
• AI agent and MCP server development
• RAG and knowledge-base chatbot development
• AI document import, export and processing automation
• Azure cloud architecture, migration and DevOps
• .NET backend and REST API development
• Full stack web application development (.NET + React / Angular)
• SaaS platform development (multi-tenant)
• Database design, tuning and migration
• Legacy system modernization (monolith → microservices)
• System architecture and technical consulting
🔄 How I work as an AI integration developer
Discovery and use-case scoping → data and system audit → architecture plan → AI prototype you can click → integration into your app → evaluation, guardrails and cost tuning → Azure deployment and CI/CD → handover with documentation → support and scaling
I send working software early and often, not status reports. You see a running prototype before we commit to the full build.

🔷 Why clients hire me as an AI integration developer
• I ship AI into real systems, not demos — integration, data and deployment are the hard part, and that's my background
• 12+ years as a .NET developer means the platform under your AI is production-grade
• One engineer for AI, backend, frontend and cloud — no hand-offs, no coordination tax
• Architecture-first: I'll tell you when AI is the wrong answer and a plain query would do
• Tested, documented, maintainable code you can hand to your own team
📩 If you're looking for an AI integration developer to add Azure OpenAI, an AI agent or an MCP server to your product — or a .NET full stack developer to modernize the platform it runs on — send me your project. I'll reply within 2-3 hours with a clear architecture plan and next steps.
Steps for completing your project
After purchasing the project, send requirements so Ivan can start the project.
Delivery time starts when Ivan receives requirements from you.
Ivan works on your project following the steps below.
Revisions may occur after the delivery date.
Systems and data mapping
We agree which systems connect, what data flows each way, and what happens when the two disagree.
Auth and sandbox setup
I get authentication working against the sandbox first, so credentials and token refresh are proven early.
