A college football roster is more than a list of stats when the goal is a Madden-ready draft class. For GridIronGC, I built the Node.js/TypeScript backend, conversion pipeline, and API, with Python stages and OpenAI-assisted data normalization. The live SaaS supports manual conversion, bulk uploads, and draft-class organization.
I shared the real product screens and backend context in the case study: https://contra.com/p/3qRLLQ6c-grid-iron-gc-or-ai-assisted-player-conversion-backend

A good donation flow needs dependable systems behind the screens. For Gabriel SGO, I built the NestJS/PostgreSQL backend for donor and school workflows, with PayPal donation processing, Redis/BullMQ background jobs, Mailgun email, and AWS delivery.
The public experience helps Ohio donors estimate a contribution, choose a school, and understand the tax-credit process. I documented the backend work and real site screens here: https://contra.com/p/Ls6L2o7Y-gabriel-sgo-or-donation-and-school-allocation-backend

ESG reporting is a workflow problem as much as a data problem: teams need applicability rules, evidence, consolidation, review, and approvals before a report is ready.
For OriginSustain, I built NestJS/TypeScript backend services, PostgreSQL and Redis/BullMQ processing, and AWS/Docker delivery with CI/CD. OpenAI API and RAG support part of the reporting flow. The screens here are from the product’s illustrative command center; the numbers are demo values, not client outcomes.
