Hire the Best OAuth Developers in Austin, TX

I help startups and product teams build or modernize SaaS and mobile products and add AI features to existing software. With 12+ years of experience, I work with React, Node.js, TypeScript, and React Native from architecture through production. Typical engagements: • Full-stack SaaS development and modernization • React Native mobile development, performance, and production debugging • AI feature integration using local or hosted models, with structured outputs, evaluation, error handling, and streaming UX • APIs, authentication, payments, accounting, search, and other third-party integrations • Architecture reviews and difficult cross-layer production issues Relevant experience: • First technical hire for a B2B fintech platform, where I helped take customer-facing and admin apps from zero to production, then expanded into Node.js and GCP backend systems, CI/CD, financial workflows, search, and accounting integrations. • Lead engineer for a React Native language-learning product that raised $1.2M on Kickstarter and launched publicly on iOS and Android. I owned its initial mobile, backend, data, authentication, and mobile 3D architecture and later led a four-developer team. • Primary engineer for a centralized OIDC/BFF identity service used by multiple products, with PKCE, Redis-backed token vaults, session security, and staged rollout. • Founder and lead engineer for an internal alpha of a local-first AI-powered application spanning Rust, Tauri, React, local and hosted models, streaming speech, memory, and evaluation. I stay hands-on while contributing to architecture, implementation, code review, testing, deployment, and clear client communication. I can join a greenfield build, modernize an existing system, or investigate a difficult production problem. If you need a senior engineer who can take ownership across product and technical boundaries, send me the product context, current stack, and the outcome you need.
