Dexter R.

Full-stack web & mobile engineering leader with a founder's mindset and a designer's eye. I've taken products from blank screen to acquisition (TableTurn.nyc) and now steer all technology at Four Hundred, a luxury concierge serving high-net-worth travelers. My stack ranges from Django, React/Next.js, React Native and iOS to AWS ECS/Fargate, Docker, Salesforce, and Stripe, backed by solid DevOps and CI/CD practice. I also build AI-powered applications, integrate LLMs into existing products, and work with conversational AI, AI agents, prompt engineering, and model evaluation. My experience includes developing AI-assisted user experiences and reviewing AI-generated code and technical reasoning. I build scalable design systems, optimize SEO and ads, and manage cross-functional teams that ship fast and polish hard. If you need someone who can architect, code, and lead, while aligning every sprint with business results, I'm your partner.
