Software engineering in Monroe, Louisiana

I design, build and fix production software for businesses and public agencies in Monroe, West Monroe, Ruston and across Louisiana: on site in Northeast Louisiana, remote everywhere else. Sixteen years of systems where failure is expensive, from payout platforms for 500K+ users at 99.9% uptime to citation-first AI for local government.

What I build

Custom software and web platforms

Multi-tenant SaaS products, client portals and back offices, built new or rebuilt on serverless and edge infrastructure, with tenant isolation enforced by the database rather than by convention.

Rebuilt a white-label, multi-tenant back office in 30 days. See the work

Payments, commissions and back-office systems

Commission engines, payouts and ledgers designed for correctness: integer-cent math, append-only double-entry records, idempotency keys and output that tests prove does not drift.

Platforms for 500K+ users at 99.9% uptime since 2012. See the work

Applied AI with citations

Retrieval systems and assistants that answer from your own documents and cite them, with confidence levels, evaluation and a human approval step where the stakes call for one.

Lead engineer on citation-first AI for city government. See the work

iPhone, iPad, Mac and Android apps

Native Swift across Apple platforms, React Native and Kotlin for cross-platform work, taken through App Store and Play review to release.

One Swift codebase built for seven Apple surfaces. See the work

Performance and reliability rescue

Finding the real cause of a slow or failing system, fixing it, and adding the queueing, load protection and monitoring that keep it fixed.

Ended an outage, then cut p90 latency 47% and dashboard abandons to zero. See the work

Event ticketing and check-in

Ticket scanning and admission flows that stay correct under crowds and bad connectivity, with no double admissions.

Built scanning and check-in for live sports crowds. See the work

Technical program management and fractional CTO

Codebase and infrastructure audits, architecture decisions, vendor review, delivery process and mentoring for teams without a senior technical lead.

Mentored 4 to 5 PMs and developers; defects down 25%, velocity up 30%. See the résumé

How engagements work

A short conversation. Email what you are trying to build or fix, and what it is costing you now.
An audit or a scoped first milestone. Either a written review of the existing system with findings ranked by risk and cost, or a fixed first deliverable small enough to judge the work by.
Build in the open. Code, cloud accounts and domains stay in your name from day one. Work ships with tests, written decisions and handoff documentation, so the system never depends on me to keep running.

Where

Based in Monroe. On site across Northeast Louisiana: Monroe, West Monroe, Ruston, Bastrop, Sterlington and the surrounding parishes. Remote for teams anywhere else in the United States.
