🏆 Full-stack engineer, Python and TypeScript/JavaScript, 20+ years building production software 🤖 Specialized in applied AI: LLM agents, RAG systems, and voice assistants that run in production, not just in a demo Tired of AI demos that wow everyone in a screen-share, then fall apart the first time a real user touches them? Or "cutting-edge" prototypes you end up babysitting that never quite reach production? That's the gap I close. I treat AI features as real software, not a wrapped API call: eval sets before anything ships, logging you can actually debug, model routing to keep the bill sane, and a human in the loop wherever a wrong answer is expensive. Whether you need an LLM agent, a RAG pipeline over your own data, a voice assistant, or the full web app around it, I build the version that still works after the demo is over. 👨💻 Core skills and technologies: \- AI and LLM: OpenAI/GPT, Claude, Gemini; RAG (hybrid search, custom embeddings); agents, tool-calling, structured outputs; eval harnesses; prompt caching; fine-tuning \- Voice: Deepgram, Twilio, real-time STT → LLM → TTS pipelines \- Backend: Python, Django, FastAPI, Node.js (Express, NestJS), Celery, PostgreSQL, Redis \- Frontend: TypeScript, React/Next.js, Svelte/SvelteKit, Vue/Nuxt \- Cloud and infra: IaC, AWS, Cloudflare, Docker, CI/CD \- Generative media: image and video generation, both hosted (Nano Banana, GPT Image 2, Seedance 2) and self-hosted open-source (Qwen-Image, Wan) in ComfyUI with custom LoRA training Send me a few lines about what you're building and where it's stuck, and I'll tell you straight what it'll take. 📩

I’m a senior mobile + backend engineer with 20+ years in software (PHP since 2002; professional since 2005) and 10+ years building mobile apps. I help teams ship and stabilize real products—especially apps that are “almost done” but stuck on crashes, performance, flaky networking, or release blockers. What I can help you with (fast, practical): • iOS (Swift, SwiftUI, UIKit): crash fixes, performance/memory, concurrency issues, architecture cleanup • Flutter (iOS/Android/macOS): reliability, state consistency, networking/retry behavior, release readiness • Backend stability (PHP/Laravel or custom, Python/Django, Rails): idempotency, queues, DB performance, webhook safety • Firebase + mobile reliability: Auth/Firestore rules, Cloud Functions patterns, analytics/instrumentation • Monetization + shipping: RevenueCat/IAP reliability, App Store Connect/Play Console, CI/CD, rejection handling Recent work includes taking a messy iOS codebase (CakeClub) to production-ready with a Firebase Cloud Functions v2 backend, stronger security patterns, CI/release automation, and RevenueCat integration; and delivering major cross-platform Flutter work (BillBlaster) including design refinements, admin tooling, and push notification features. If you come with logs/screenshots (Crashlytics traces, network errors, repro steps), I’ll give you a clear diagnosis and a prioritized fix plan—and if it makes sense, I can execute the fixes as a focused sprint.
