Project details

I turn product ideas into production-ready web applications. As a two-time CTO who has built and scaled platforms from zero to millions of users, I bring deep expertise in React, Next.js, Node.js, Python, and AWS to every engagement. You get a fully deployed MVP with authentication, database, API, responsive UI, CI/CD pipeline, and cloud infrastructure — not just code, but a product ready for real users. I handle architecture decisions, third-party integrations (Stripe, Auth0, SendGrid, etc.), and deployment so you can focus on your business. Every project includes clean, documented source code you fully own.

About John

John S.Status: Offline
Engineering Leader & AI-Native Product Builder | CTO | Full-Stack Arch
Denver, United States - 10:20 am local time
I'm a hands-on engineering leader and two-time CTO with 15+ years of experience building production software — from embedded systems at Boeing to AI agent platforms processing millions of documents.

AI-NATIVE DEVELOPMENT: I've been shipping LLM-powered products since 2020. I've built production AI agent runtimes, custom Claude API integrations, RAG pipelines (LangChain/LlamaIndex), and multi-model orchestration layers. This isn't side-project experience — these are products serving Fortune 500 clients and processing real workloads at scale.

FULL-STACK ARCHITECTURE: TypeScript, Python, Java across the entire stack. Next.js + React frontends, Node.js/NestJS/GraphQL backends, event-driven systems on AWS (EKS, Lambda, SQS). I've designed platforms handling 50M+ messages/month and built systems from zero to Series A.

ENGINEERING LEADERSHIP: I've scaled an engineering org from scratch to 90 engineers, built the management layer, and led cross-functional teams of 10-20 through product development cycles. I know how to hire, ship, and keep teams healthy.

0-TO-1 PRODUCT BUILDING: Two startups as technical co-founder/CTO. I've raised Series A funding, served Fortune 500 clients, and invented domain-specific languages to make complex systems accessible to non-technical users.

I work fast, communicate clearly, and care about building things that actually work. Whether you need an AI agent prototype, a full-stack MVP, a system architecture review, or a fractional CTO — I can hit the ground running.
