About Jerry

Jerry A.Status: Offline
Backend & Full Stack Engineer FastAPI, Node.js, React Native
Manchester, United Kingdom - 9:25 am local time
I’m a Backend & Full‑Stack Engineer with real industry experience delivering production‑ready software during my placements at PA Consulting and Ovarro. I now work at OCU Group, contributing to backend systems built with Ruby on Rails.

I specialise in building fast, reliable, and scalable systems using Node.js, Express, Python, FastAPI, Ruby on Rails, React Native, Vue.js, and Docker.

I’ve built everything from full‑stack social platforms to cryptographic image‑verification systems, mobile apps, and multithreaded Java applications. My work spans backend architecture, API development, authentication, mobile features, and deployment pipelines — giving me the versatility to support both early‑stage startups and established engineering teams.

You can view examples of my work and projects at jarthur.dev

What I can help you with:

Backend development (FastAPI, Python, Node.js, REST APIs)

Full‑stack web apps (Vue.js, JavaScript, Bootstrap, SQLite)

Mobile development (React Native + Expo)

API design, integration, and optimisation

Authentication, tokens, and secure data flow

Debugging, refactoring, and performance improvements

Docker, Linux, CI/CD pipelines

Java socket programming, concurrency, and server‑client systems

Why clients work with me:

Real engineering experience

Strong communication — clear, fast, and reliable

Clean, maintainable code following best practices

Ability to quickly understand existing codebases

Comfortable working independently or within Agile teams

Fast turnaround on small tasks and consistent delivery on larger projects

If you need a dependable engineer who can build features, fix issues, improve performance, or take ownership of backend and full‑stack development, I’d be happy to help. Let’s build something great.
