I build and ship production React Native apps — and the full backend and AI systems behind them. My flagship app, NotePal, is live on Google Play: an AI study tool that turns audio, PDFs, YouTube links, and text into notes, quizzes, and flashcards. One FastAPI backend powers both the React Native mobile app and the web app, with cross-platform subscriptions handled through RevenueCat (mobile) and Stripe (web). It's a real, monetized product in a store — not a demo. That's the difference I bring: I don't just build the screens, I ship the whole thing — store submission, in-app purchases, billing webhooks, and the scalable backend that keeps it running cheaply at volume. What I build: - Cross-platform mobile apps (React Native — Android & iOS), including store submission and in-app purchases (RevenueCat) - AI-powered apps (OpenAI, Claude, RAG pipelines, vector search with Pinecone) - SaaS platforms — multi-tenant architecture, auth, billing, dashboards - Full-stack web apps (Next.js, React, TypeScript, FastAPI, Node.js) - Backend & cloud infrastructure (AWS Lambda, SQS, Fargate, Docker, CI/CD) Recent work: - Built NotePal end-to-end — React Native app + web + AI backend — offloading heavy work (PDF/YouTube/long-audio processing) to serverless Lambdas to keep cloud costs low - Built GeoScraper, a B2B SaaS with a credit-based billing engine handling concurrent, race-condition-safe transactions - Lead full-stack development and DevOps on a HIPAA-compliant healthcare platform — encryption, RBAC, audit logging, CI/CD, and production reliability I'm a strong fit if you're: - Launching a mobile app and need it built, monetized, and shipped to the stores - Building an AI or SaaS product and want it production-ready, not a fragile prototype - Scaling an existing app without a costly rewrite Send me a message with what you're building. I'll reply with an honest technical assessment and the fastest path to shipping it.

We used 2 other SQL engineers prior to meeting Shafir and also attempted a repair using a database repair application which also failed. We were at a point where nothing was working and we were coming to the conclusion that this was not repairable as there were too many errors. Shafir was very confident that he could repair the database and after watching him work for just a few minutes I immediately felt some hope of a successful repair. After working on the database for several hours Shafir managed to repair the database and get it working better than it was before. Working 20 years in IT I had never seen anything like it. Shafir is very professional and truly an SQL expert. I would highly recommend Shafir for any SQL project. Thank you." - Dean Cutajar, Director - Access IT ⭐⭐⭐⭐⭐ "Amazing experience! Shafir did the impossible. He was able to take a highly corrupted database and bring it back to life with zero data loss. Once repaired, he optimized the database and has it running better than it was before the corruption. He is responsive and easy to work with. Highly recommended. Will use again in the future."
