Logan Sinclair.

Software engineer in Oklahoma City. Most of my work is on systems that can't quietly fail: the payroll engine at Paycom that touches every paycheck, and BuzzIn.Live, a quiz platform I've run since 2018 with over 100,000 monthly players.

Where I've worked

2023to now

Software Developer IV and Project Manager

Paycom, Oklahoma City

Promoted from Level III to Level IV in August 2024. I lead multiple projects from scratch, coordinating between end users and development. I maintain and extend the central payroll calculation engine used by nearly every payroll process. Part of the multi-year port from Visual FoxPro to .NET 10 with near-zero operational downtime; designed the point-in-time snapshotting tools for deterministic calculation recreation; extended the CI/CD pipeline to build, containerize, and deploy an isolated test environment per engine change, with AI code review in the loop.

BuzzIn.Live

Founder, solo build

A real-time multiplayer quiz platform for quick quiz-bowl style games, built from scratch and running since 2018. Full-stack on a VPS: Node.js backend, NGINX proxy, Socket.IO for the live buzzing. Over 100,000 monthly players. It ran on a freemium model for several years before I made it fully free in July 2025.

Payroll engine modernization

Paycom, Software Developer IV and Project Manager

A multi-year team effort porting the central Visual FoxPro payroll engine to .NET 10 with near-zero downtime. I designed point-in-time snapshotting to eliminate drift between parallel engine runs, and extended the CI/CD pipeline to spin up an isolated test environment for every change.

Radar chiller telemetry tooling

OU Advanced Radar Research Center, undergraduate assistant

PyQt utilities for the lab, plus a LabVIEW application that polls chiller telemetry over Modbus in real time.

2022to 2023

MBED Guitar Hero

University coursework, embedded

A complete rhythm game on the MBED LPC1769 in bare-metal C, no RTOS. Real-time audio synthesis driven by hardware timers and PLLs, input from a rewired guitar controller, and game state and UI on a four-line LCD. This is the project that got me interested in embedded and firmware work.

Death Star Orb warehouse scanner

University capstone, for a battery warehouse client

A staff-mounted scanning orb the operator carries through the aisles. Raspberry Pi 4 brain, UPS-backed power for a full shift, an I2C 2D barcode scanner, and audio feedback through an onboard amp and speaker. A team build, end to end: hardware integration, power management, and the operator-facing audio cues.

Non-visual VR navigation

University senior project

A haptic-only VR navigation experiment: can you convey spatial awareness with no visual channel at all? Distance-based pulse modulation turned proximity into vibration patterns, then user trials compared feedback styles. The data was as much of the project as the build; we collected and analyzed trial results to see which patterns actually let people navigate confidently in the dark.

2018

Big M Construction site and hiring portal

Client work

A custom marketing site for an oil and gas pipeline construction company. Node.js and NGINX, no framework. Later extended with an internal employment application system: applicants submit, staff review submissions in a dashboard.
