⭐ 80+ Projects Delivered | $70K+ Earned | 100% Job Success | 10 Years on Upwork Not just a developer. A technical partner who gets your product shipped — and leaves your team able to own it after I'm done. I work with founders, CTOs, and product teams building .NET backends that actually scale. From greenfield SaaS to legacy ASP.NET migrations to microservices rewrites — I've done it across Healthcare, Cybersecurity, SaaS, Travel & Hospitality, and EdTech. 🔧 Sound familiar? • Your SaaS backend wasn't built to grow — and it's showing • Legacy ASP.NET app drowning in technical debt • APIs are slow, DB queries are timing out, users are complaining • You need microservices but don't know where to start • Cloud costs are climbing with nothing to show for it 🚀 How I work: Discovery → Architecture → Build → QA → Deploy → Scale No hand-holding needed. You describe the problem, I own the solution end to end. 💻 Core Stack: → Backend: ASP.NET Core, C#, Web API, EF Core, Dapper → Frontend: Angular (2–18), React, Next.js, TypeScript → Architecture: Clean Architecture, Microservices, CQRS, DDD → Database: SQL Server, PostgreSQL, Redis → Cloud & DevOps: Azure, AWS, Docker, CI/CD, Hangfire → Auth & Security: JWT, OAuth, Identity Server, HIPAA-aware 🎯 I can plug in as: ✅ Senior developer on your existing team ✅ Tech lead owning architecture decisions ✅ Fractional CTO for startups without a technical co-founder Let's build something that doesn't fall apart at scale.

🤖 I build production AI systems - not API demos. I'm Dmitry, an AI Engineer with 10+ years of full-stack background. I help SaaS, crypto, and digital product companies ship AI features that work with real users - at scale, within token budgets, with proper fallbacks. The difference matters. Anyone can call the OpenAI API in a tutorial. The hard part is making AI features that don't break in production: conversation memory that persists, prompts that survive edge cases, streaming that handles network drops, and costs that don't spiral. That's what I do. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎯 What clients hire me for ✅ Custom ChatGPT / GPT-4o / Claude integrations into existing apps ✅ RAG systems with vector search over business documents ✅ AI chatbots & assistants with persistent context (web + mobile) ✅ AI workflow automation (n8n + LLM for ops) ✅ Token cost optimization & prompt engineering ✅ Taking AI-built MVPs (Lovable, Cursor, Bolt) to production-grade ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📂 Recent production AI work 🔹 HOMI - Learning platform with ChatGPT-powered lesson generator Built GPT-4 integration into live LMS app with paying users. Custom prompts, streaming responses, conversation memory, ChatGPT-driven sample conversations, fallback handling. Live for 2+ years. $26K+ delivered across 4 contracts - same client kept coming back. 🔹 TapSwap - Gamified learning center for crypto exchange Built end-to-end LMS with 70 educational articles, 820 quiz questions, real-time leaderboard, reward redemption system. Angular + Firebase + custom gamification logic. 🔹 Style 220 - AR mobile app for VIMAR (Italian electrical products) Augmented reality "try-on" for switches and sockets in interior settings. iOS + Android, integrated with online store and order placement workflow. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🛠️ My technical stack AI: OpenAI (GPT-4o, GPT-4, DALL-E, Whisper), Claude API, LangChain Backend: Node.js, NestJS, Express, Firebase Cloud Functions Frontend: Angular, Ionic, TypeScript, RxJS, Tailwind CSS Mobile: Hybrid apps (Ionic + Capacitor) for iOS & Android Databases: Firestore, MongoDB, PostgreSQL Cloud: Firebase, GCP, AWS, Vercel, Cloudflare Automation: n8n, MakeCom, webhook orchestration ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🏢 Backed by WhyNet Agency I work with a senior team of 4 engineers + 1 PM under WhyNet - 8 years on Upwork, 100% Job Success, $500K+ delivered, 84 completed projects. This means: senior code review on every project, dedicated project manager keeping communication on track, additional engineering capacity when scope grows beyond what one developer should handle. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💼 How I work → Async-first communication. No 5-call discovery loops before contract. → Structured PDF proposal within 24-48h after we discuss your project. → Weekly demos so you see real progress, not status reports. → Production-grade code with proper architecture, error handling, testing. → Direct and honest. If something won't work, I'll tell you before we start. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎯 I work best with ✓ SaaS founders adding AI features to existing products ✓ Crypto / Web3 teams needing chatbots, RAG, or AI tooling ✓ EdTech companies building AI-assisted learning experiences ✓ Companies taking AI-generated MVPs to real production ✓ Teams replacing manual operations with n8n + LLM workflows ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✨ Ready to start? Send your project description - you get a structured proposal in 24-48h. Not a generic "let's hop on a call" template. - Dmitry · WhyNet CTO
