Chris I.

Senior full-stack engineer and consultant. I design and build the software behind fintech, SaaS and AI products, from the first screen to the production system, and I review the ones that have stalled.

Led UX and built the real time portfolio dashboards Most of what I am called in for is one of three things: • A product that needs a senior engineer to get it built properly: a SaaS platform, a customer portal, an internal tool, an AI feature grounded in your own data • A technical review before a decision: an audit of an existing codebase or an AI built app, an architecture review before you scale, a second opinion on a plan or a vendor choice • A fintech or regulated product where the details have to be right: payments, lending flows, compliance workflows, role based access AI PRODUCTS - - - - - - - - - - AI assistants and search grounded in your own data, on a predictable backend first LLM features built into real products with OpenAI and Claude: summaries, extraction, natural language queries over your data Agents that take actions inside your product, with limits, logs and a human in the loop An AI native commercial real estate platform with a built in voice assistant for deal queries SAAS, PLATFORMS AND PORTALS - - - - - - - - - - Multi tenant SaaS with accounts, roles and billing Dashboards, admin tools and internal software in React, Next.js and TypeScript Client and customer portals with search, filtering and file delivery Intake forms, multi step applications and approval workflows Stripe payments, subscriptions and checkout flows, plus booking and inventory systems, one of which cut errors by 40% Scorecards, assessments and data visualization for institutional clients API, CRM, Zapier and Make integrations that take out repeat manual work FINTECH AND REGULATED PRODUCTS - - - - - - - - - - Consumer finance onboarding, funding and lending flows at scale Real time financial dashboards for high frequency use Trade surveillance, market abuse detection and regulatory reporting for compliance teams Healthcare: the guidance platform for a Gates Foundation and Gavi funded global health program, bilingual and WCAG 2.1 AA, and B2B healthcare SaaS earlier in my career A business lending site built to convert, with ongoing SEO TECHNICAL REVIEW AND ARCHITECTURE - - - - - - - - - - Code and architecture review with a written list of what to fix first and why A review of an AI built app before it goes in front of customers: logins, data rules, payments, security Front end architecture and component libraries for teams that are about to grow ECOMMERCE AT THE PLUS END - - - - - - - - - - Shopify Plus builds, custom checkout with Checkout Extensibility and Shopify Functions, Klaviyo and subscriptions Results include a 65% mobile conversion lift on a Shopify Plus redesign and sales up 50% in six months on a Shopify store rebuild WEBSITES - - - - - - - - - - Most products start with a site.

I design in Figma and build what I design. I scope in writing before anything is built, and I raise the decisions that get expensive later while they are still cheap to change. Techstars alum. 500+ projects over the past decade, including work for teams backed by Coinbase Ventures and Sequoia whose products have raised more than $1B between them. Send me what you are building and what it has to do. I will tell you what I would build first and what it would take.
