WHO I AM

I'm a second-year Computer Science student at Northumbria University (final semester of Level 5, starting Level 6 in September 2026) who ships real products — not just university assignments.

BSCAN is a live SaaS website audit tool at bscan.balancewises.io — scanner, AI fix generation, deep crawl, Stripe billing, team spaces, PDF export, social posting engine, and a full admin console. Wisers is a professional social network at wisrs.com (in development) — E2E encrypted DMs, passkey login, Cloudflare R2 media, and an API platform.

I also founded Balancewise Ltd (Company No. 16164776) — a multi-brand UK group covering IT services and clothing, where I manage all technical infrastructure, DNS, email, cloud identity, and compliance.

I'm actively looking for a placement year, contract, or graduate developer role where I can contribute from day one.
