Dmitry V.

🤖 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
