About

Hi, I’m Justice, a senior full-stack engineer with 6+ years of experience building and maintaining production web applications, with strong backend depth across API design, database modeling, integrations, and scalable feature delivery.

I’ve worked extensively with Laravel/PHP, Node.js, Vue, React, MySQL, Redis, queues, background jobs, and third-party integrations. I’m especially comfortable owning backend-heavy systems end to end: designing the architecture, implementing the core logic, handling edge cases, improving reliability, and communicating trade-offs clearly.

What stood out to me about this role is the need for someone who can think beyond tickets and take ownership of core product systems. That matches how I like to work. I’ve shipped features independently, collaborated closely with founders and product teams, and taken responsibility for clean handoffs, maintainability, and production outcomes.

I also have experience working on subscription/payment flows, API-driven applications, structured data handling, and performance-sensitive backend logic, which aligns well with your work around workout/nutrition engines, mobile-facing APIs, and integrations like Stripe, RevenueCat, Zendesk, and nutrition APIs.

I’d be excited to contribute as part of a focused in-house contractor team, especially in a growth-stage environment where speed, judgment, and ownership matter.
