Hi, I'm Ifeoluwa Adeagbo Full-Stack Developer
I build web applications from the React interface to the PostgreSQL database. One of them is a live online store with a full Stripe checkout.
I also run a Windows Server lab at home, because I like knowing what the application is sitting on.
Technical expertise
I work across the whole stack, from what the user sees down to the network the server runs on.
Backend
Node.js, Express, NestJS, REST APIs, Stripe payments, Claude API
Databases
PostgreSQL, Sequelize, relational data modelling, SQL
Infrastructure
Linux, Windows Server, Active Directory, DNS, DHCP, NAT routing
Also in the toolbox
Git & GitHub
Automated testing
Vercel
UTM / QEMU
AI-assisted development
Projects
Four things I have built. Two are deployed, one lives on my own hardware, and one is in progress.
Live
E-commerce
Hailplus
An online store for a small UK business, with browsing, cart and a Stripe card checkout, plus an admin panel for products, orders and refunds. Payments are currently in Stripe test mode.
- Row locking at checkout, so two customers can't both buy the last item
- Idempotent Stripe requests: a retry or duplicate webhook can't charge or refund twice
- Two-factor sign-in, with the secrets encrypted in the database
- 124 automated tests, run on every push
Live
Energy & climate
Carbon Helper
Tells UK households the lowest-carbon time to run their appliances, with an AI assistant, HailplusAI, that answers questions using live grid data.
- Finds the cleanest half-hour slots for each appliance, with the CO₂ saved and a calendar export
- AI assistant on the Claude API that can only quote figures fetched through its three tools
- Hard limits on steps, tokens and tool time, plus daily rate limits in Redis that fail closed
- 79 automated tests, including scripted model replies that check every limit and failure path
Home lab
Infrastructure
Windows Server Lab
A Windows Server 2019 environment I built to learn how the services under an application fit together.
- Active Directory domain controller with DNS and DHCP
- NAT routing across separate internal and internet adapters
- Moved from VirtualBox to UTM/QEMU after an ARM and x86 mismatch on Apple Silicon
Runs on UTM / QEMU on an Apple Silicon Mac
In progress
Healthcare
GP Registration Platform
An NHS-style system that models how patients register with a GP practice.
- Built on the PERN stack: PostgreSQL, Express, React and Node.js
- Relational data model for patients and practices
- Designed around handling personal data carefully
About me
I'm a full-stack developer based in Glasgow. I enjoy taking an idea all the way through: designing the database, building the API, shaping the interface and putting it online for real people to use.
My degree is in Medical Physiology. It taught me to form a hypothesis, test it and check the result before trusting it, and I debug software the same way.
Alongside development I'm studying for the Cisco CCNA, which covers how networks are built and run: IP addressing, routing, switching and network security. It means I can follow a request all the way from the browser to the server, and troubleshoot the systems my code depends on.
