🏆 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 do it all, I do iOS (swift and Obj C) , Android (Kotlin and Java), front end (I use my own JS framework, although I know vue or react), and Node Js for my back end, I prefer MongoDB, but I can use SQL like Postgres, Been programming for nearly 20 years so I know the ups and downs. I have clone Uber, Twitter , Tinder and other major apps for clients, like "tinder for job matching between employers and candidates".
I've been teaching programming since 2018 to people of different ages. I'm specialized mostly in teaching how to start programming from scratch: basics of programming languages + basics of computer science. But I always have in mind a long-term perspective for my students and try to develop useful skills just from the start of our work.

I have a long-standing passion for coding, and have received great feedback as tutor & mentor over 10+ years as a Software Engineer. I have an expert mastery of Javascript, Typescript, C#, GIT, CSS, HTML, and have implemented solutions at all levels of the tech stack. I feel strongly that software is built for people, and not the other way around: I strive to provide solutions that meet people where they are. As a programming language enthusiast, I have explored many languages & paradigms, both in terms of practical use and underlying mechanisms. This has given me a uniquely strong ability to: implement solutions that closely match human mental models; understand solutions apart from their coded form; spot incidental complexity in code; deconstruct and re-implement complex code-bases (e.g. when migrating legacy software). As a tutor and mentor, these experiences enable me explain things in human terms, and empathize with the gap between technology and the human mind. My favorite experience as both a software engineer and mentor, is that spark of discovery or understanding while walking someone (or vice versa) through a problem or explanation. Other interests: Piano, Stargazing, Hiking, Camping, Yoga, Mindfulness, Reading, Origami, Retro gaming, Sci-fi, Horror, Dad jokes, Playing with my kids & my dogs.
