“It was great working with Raz. The website is modern and user-friendly, matching the colours and theme of our branding, and it works really well on mobile — our customers now have an easy-to-use digital menu directly from a QR code. Delivery was fast and Raz always implemented changes quickly. I would recommend him to all other businesses; he knows his craft well, is very professional and extremely helpful.”

“Masha’Allah, this website is amazing. Razwanul saved me from a scam developer who delivered a very bad Wix website after months and over $1,000 spent.”

05 · Why hire me

Ex-commercial banker.
Ships the engineering.

Two years inside a UK high-street bank taught me what money, risk and regulated environments actually feel like — fraud reviews, KYC, audit trails, the cost of shipping the wrong thing. Now I bring that judgement to the build: clean architecture, honest scope, and code that survives contact with real users.
