Matthew E.

Founder-architect with ~20 years in startups. I help founders turn ideas into AI-powered SaaS products that actually ship, scale, and sell. I've been the technical lead inside startups across fintech, proptech, B2B marketplaces, the creator economy, and blockchain, from first prototype to production systems serving millions of users. Today I run Jupiter Software, a technology co-founder studio for early-stage teams. Recent work • Orchid: Lead engineer on a real-time AI production assistant for podcasters and creators: guest research, live coaching, mid-conversation fact-checking, and instant transcripts (Rust, Python, React). 2,200+ hours on Upwork. • UX Chain (formerly Umee): Head of Infrastructure for a Cosmos layer-one blockchain. Automated test networks with Pulumi/Go and built and trained the DevOps team. • HelloTech: Microservices and database/protobuf schema design for a B2B platform serving Walmart, Amazon, and SimpliSafe. • Endpoint: Helped lead a monolith-to-microservices transition and legacy-database integration for a fintech disrupting escrow and mortgage. • Weedmaps: Rebuilt the Elasticsearch search engine with custom relevance weighting. • JupiterSoft Games: our own little studio. Curbside (pixel-art street hustle game) and Red Hope (3D Mars colony survival sim), both shipped as public demos and built in the open. What I do best • AI product development: LLM integration, real-time pipelines, and AI features that hold up in production • MVPs & product strategy: scoping, validating, and shipping the smallest product that proves the business • System architecture: microservices or monolith, chosen for your stage • Database engineering: schema design, performance tuning, SQL & NoSQL • DevOps & cloud: CI/CD, infrastructure as code, automated deployments • Blockchain: DeFi protocols, smart contracts, cross-chain infrastructure How I work Prototype boldly, pitch clearly, launch imperfectly. You get senior judgment, fast communication, and code built for where your product is going, not just where it is today. Available for short-term projects, fractional CTO / architecture roles, and long-term builds.
