I help organizations build, modernize, and scale enterprise applications using .NET Core, Angular, and secure API-driven architectures. I’m a senior full-stack engineer with 10+ years of hands-on experience delivering production-grade systems such as ERP/CRM modules, financial workflows, internal dashboards, and cloud-hosted business applications where reliability and data integrity are critical. Clients typically work with me for: Building and modernizing .NET Core / ASP.NET applications Developing Angular-based frontends for complex business systems Designing secure REST APIs with proper authentication, authorization, and role-based access Database design and performance tuning using SQL Server and PostgreSQL Integrating third-party platforms such as QuickBooks (accounting, invoicing, sync workflows) and other business services I also integrate AI capabilities into enterprise systems when they provide real value—such as document processing, intelligent search, data classification, workflow automation, and GPT-based features embedded directly into .NET applications. In addition, I’ve worked on map-based and geospatial features, including Google Maps and ArcGIS integrations for location tracking, visualization, and operational dashboards. On the infrastructure side, I have experience deploying secure .NET applications to Azure, using App Services, SQL Azure, Key Vault, and CI/CD pipelines. I follow clean architecture, SOLID principles, and clear separation of concerns, focusing on boring, stable solutions that are easy to maintain and scale over time. If you need a dependable .NET & Angular engineer who can handle AI integrations, business systems, and complex enterprise workflows, I’m ready to support your team.

🏗️ I ship production AI. RAG, multi agent systems, voice pipelines the kind that survive contact with real users and real load. Most don't. Mine are built to. 📊 61 contracts. $100K+ delivered. Top Rated Plus, 100% JSS. Right now I'm 1,040+ hours into an enterprise Azure OpenAI build, owning retrieval quality and reliability. 🔍 RAG that holds up A demo that works on ten documents is not a system. Hard part is scale bad chunking, silent hallucination, retrieval that misses the one clause that mattered. I engineer for that from the first commit: structure-aware chunking, hybrid retrieval across Qdrant, Pinecone, Weaviate, or FAISS, source citations on every answer, and an evaluation harness so accuracy is a number I can show you, not a claim. 🤖 Agents that take real actions A single clever prompt is fragile. I build multi-agent systems in LangGraph with scoped tool-binding, shared memory, async coordination, and a verifier gate before anything writes to a real system. CrewAI and AutoGen when they fit. Workflow agents for ops, support, and sales with a full execution trace when something goes wrong. 📞 Voice AI tuned for latency Real time STT → LLM → TTS using Retell, VAPI, Deepgram, ElevenLabs, and Twilio tight enough that callers don't hang up. AI receptionists, call routing, booking flows, analytics logged straight to the CRM. ⚙️ The connective tissue n8n, Make, and Zapier automation driven by OpenAI, Claude, and Azure OpenAI. CRM work across HubSpot, Salesforce, and GoHighLevel. Custom MCP servers so agents reach internal tools through a permissioned, audited interface not raw API access. ✅ What production means to me It ships with error handling, logging, evals, and documentation. It survives the edge cases. It hands off clean. 💬 Before you message me, I do best with a defined problem and a real outcome in mind. Send the scope, or the rough shape of it. I'll tell you straight whether it's a fit and how I'd build it.

💫 The Story Started as a broke philosophy student in Kyiv who taught himself Python to automate his part-time job at a logistics company. Accidentally built an ETL system that saved them $50K annually. Philosophy degree? Abandoned. Data engineering career? Born. 💭 Philosophy "Data engineering is like being a digital architect, plumber, and fortune teller all at once. We build the invisible infrastructure that powers tomorrow's innovations, fix the pipes when they break, and predict what will break next. It's the most beautifully chaotic job in tech." 📍 Currently: Building the future of financial data while chasing the perfect work-life-travel balance 🎪 Fun Fact: Once fixed a critical production bug while stuck in a Romanian cable car during a thunderstorm. The WiFi was surprisingly good.

⭐ Legacy System Modernization Expert | Django, FastAPI & Next.js Developer With 90+ completed projects and a 100% Job Success Score, I help businesses that have outgrown Excel and MS Access move to modern, scalable web applications. My background is unusual: I've spent years inside Access and Excel systems, so I understand exactly where they break down as a business grows — messy data, no real-time reporting, no multi-user support, no integrations.
