Backend architecture
REST APIs, authentication and data models, built in clear layers so they stay easy to change as the product grows.
Node.js · Express · Spring Boot · Django · .NET
Backend depth,
full-stack perspective.
I build web applications, APIs and the infrastructure behind them. My work spans product development, cloud deployment and custom websites for businesses.

Expertise
Four things
I do well.
Most of my work sits behind the interface: the API, the data and the servers it runs on. I care just as much about the part people see.
Cloud & delivery
Deployments on AWS behind Nginx and PM2. I set up the domains, TLS and CI myself, and keep things running afterwards.
AWS · Docker · Nginx · PM2 · CI/CD
Product interfaces
Responsive interfaces in React and Next.js, with the same attention to typography, motion and accessibility as the API underneath.
React · Next.js · TypeScript · Tailwind
Security
JWT and OAuth 2.0, role-based access and input validation, designed in from the start rather than added at the end.

Selected work
Four projects,
in detail.
A live AI product, a support platform for underserved communities, the client studio I co-founded, and a ticketing platform I'm building now.

More projects
Select a project to read moreGrade Submission API
REST API for academic grade management with JWT authentication and role-based access control.
Designed and built a stateless REST API with Spring Boot and Spring Security. Implements JWT-based authentication, role-based authorization (admin / instructor / student), input validation, structured exception handling, and a layered architecture (controller, service, repository) that follows REST conventions throughout.
Java · Spring Boot · Spring Security · JWT · PostgreSQL
Encrypted Chat App
Real-time encrypted chat system built on Python socket programming with end-to-end SSL/TLS.
Built from the transport layer up using raw Python sockets over TCP with a custom application protocol. Implemented end-to-end SSL/TLS encryption, concurrent client handling via threading, and a Django backend for session management. The socket lifecycle is managed directly, with no framework abstractions on top.

Workout Tracker
Geolocation-based fitness tracking app with interactive maps and OOP-driven architecture.
Built with vanilla JavaScript using an OOP class hierarchy for workout types (Running, Cycling). Integrates the Geolocation API for live position, Leaflet.js for interactive map rendering and route markers, and localStorage for persistence, without a framework.

CareTrack Network
Healthcare network management system with relational data models, full CRUD, and clean MVC architecture.
Built with ASP.NET MVC and Entity Framework Code-First for a multi-entity healthcare platform. Full CRUD operations across patients, providers, and facilities with relational integrity, database migrations, and clean separation between controller logic, business rules, and data access.

On AI
A creative tool,
not a copy-paste one.
I use AI every day to explore ideas, sketch approaches and move faster through routine work. But I don't ship code I can't explain. What an engineer brings is judgement, and judgement comes from understanding how things work.
- 01
Understand it before you ship it
If AI drafts a function, I read it, test it and make sure I could have written it myself. Code I can't explain is a liability, not a shortcut.
- 02
Know how the models work
Every engineer should understand the basics: how a model predicts the next token, why it can be confidently wrong, and where its context and data run out. That's how you know when to trust it.
- 03
Go further, don't think less
The best use of AI is trying more ideas, learning faster and spending more time on the hard problems. The judgement stays with the engineer.
About
From the first idea
to production.
A software engineering graduate who likes taking a product from an idea to something running in production, and then looking after it.

Scale a system yourself. Add servers, a cache or a CDN, keep latency and errors under target, and stay within budget. The maths is simplified; the trade-offs are real.
On-call noteOne API server at 200% and there's no way to add a second without a load balancer.
The product goes live this morning. One server and one database won't hold 1,200 requests a second.
