Joe Felicidario · Software Engineer

I build software that tracks other people’s money, so I care most about the parts that must not be wrong. These days that means leading the V2 platform at Legacy Farmer.

Experience

Legacy Farmer

Lead · V2 platform Now
  • Started the V2 platform as a side project on my own time, then made the case to rebuild the company roadmap around it. Now I lead it: TypeScript monorepo, Fastify and tRPC API, React 19 SPA, PostgreSQL with row-level tenant isolation.
  • Closed off the ways the platform could lose or corrupt financial data: idempotent writes, whole-row compare-and-set concurrency control, BigInt-cents money math, and a golden-master suite that fails CI if any report drifts by so much as a cent.
  • Shipped an AI assistant that can propose any change the user could already make by hand. Its tools run the same permission and row-level-security checks as the API, every write waits on human confirmation, and a PostgreSQL trigger keeps 180 days of undo.
  • Built the AI tooling the team works in every day: agent skills for code review and pre-release audits, a Slack PR bot, and the architecture docs they all read from.

  • Built and maintained Playwright end-to-end suites across client web apps, each one a different product and stack.
  • Turned client requirements into test plans, then into automated coverage the client could run themselves.
  • Worked on the internal infrastructure those suites ran on.

Ventures

nuplera

Next.js · Postgres · Stripe

Finds where an adult’s math foundation first cracked, arithmetic through Algebra 1, then puts the repairs in order. An adaptive Elo/Rasch engine traces every wrong answer back to a root cause. Teaching is deliberately out of scope.

type.

Next.js · MongoDB

A typing platform built on a custom grapheme-safe engine, so emoji and combining marks count as one keystroke instead of several.

greenlit

React · React Native

A ride-sharing app for my hometown, on web and mobile, with live ride tracking and payments. I owned the product decisions as well as the build.
