Sheriff O.

I help startups and founders build AI products that hold up in production, not demos that break the moment real users show up. Over the past 5+ years, I've taken web and mobile products from idea to launch as a full stack developer, building systems that handle real traffic, real payments, and real AI workloads without falling apart after deployment. Most of my work sits where product meets engineering, where decisions about architecture, performance, and scalability directly shape how fast a SaaS can grow. I typically help clients with: • Building AI SaaS platforms and MVPs from scratch, idea to paying users in 2 to 4 weeks • Integrating AI and LLM features (chatbots, content generation, RAG, recommendation engines) • Fixing or scaling existing apps that are slowing down or breaking under load • Developing APIs and backend systems that support complex workflows • Creating fast, responsive web and mobile apps users actually enjoy On the frontend, I build clean, high-performance interfaces with React, Next.js, and React Native. On the backend, I design reliable systems with Node.js and Python (FastAPI), backed by PostgreSQL and Supabase, and I architect AI in from day one using LangChain, OpenAI, Claude, and Gemini rather than bolting it on later. Clients usually come to me when: • Their app works but doesn't scale • Their codebase is messy and needs structure • They need someone who can own features end to end without constant hand holding What you can expect working with me: • Clear communication and structured execution • Honest timelines and thoughtful engineering decisions, not shortcuts that cause problems later • Production-ready systems built to last If you're building something serious and need an engineer who can step in and deliver without drama, send me a message and let's talk through your project. Available now. I typically respond within 2 hours.
