That is a design problem. It is the one I solve.
Founders have raised $3.3M on products I designed.

Seven years in, I work with founders building genuinely complicated products: AI tooling, billing engines, ticketing platforms. My job is to make them feel obvious.
That means getting inside the problem with you, not waiting for a brief. Research, flows, interface, design system, and a handoff your engineers can build from without guessing. I stay until it ships, because design that never ships proves nothing.
Right now I am a product designer at AD Group, working on property tech: the Development ID web app for property developers, and Leasey, a commercial leasing platform for agents, tenants, and landlords. I take on a small number of founder projects alongside it.
I am based in Dhaka on GMT+6 and work remotely with teams in Australia, the US, and Europe. Most founders hear back from me the same day.
A blank page to an enterprise-ready AI coding platform. I built the product experience and the design system behind it, and the team raised $1M pre-seed on the back of it.
Datalogz had the data. Getting to it was the problem. As founding designer I redesigned navigation, dashboards, and onboarding, and the company raised $2.3M in seed funding after Fortune 500 pilots.
Thousands of Australian organizers were losing sales in a checkout that fought them. I rebuilt the flow end to end, and traffic and revenue followed.
Trade finance still runs on email and fax. I designed the loan management system that put buyers, suppliers, and banks on one automated ledger, with banking approval rules built into the flow.
Billing and ERP are where SaaS products usually turn ugly. I led the design team that rebuilt Exsited from scratch into something finance teams enjoy using daily.
Nintendo's warranty and repair claims ran on manual process with no shared visibility. I designed the multi-portal platform solo, connecting retailers, consumers, and staff on one system.
Buying a plugin used to be where the easy part ended. I designed the marketplace purchase flow and the backend install UX as one continuous path, from browsing to a live, configured feature.
SaaS interfaces, dashboards, and products carrying a lot of data.
Systems your engineers can build from, shipped across five products so far.
iOS, Android, and hybrid apps people actually enjoy opening.
I find what is costing you users, then show you how to fix it.
One big design problem, solved in days instead of months. Best for MVPs, landing pages, and UX audits.
Your design team, without the hiring. Ship faster, look sharper, stay ahead.
“Saiful's professionalism and quick technical execution in UX design made him an invaluable asset to the Sentellent team and beyond.”
“Saiful's elegant and creative approach to UI/UX across SaaS and B2B projects significantly enhanced our product experience and drove customer satisfaction.”
A Design Sprint starts at $1,500 and solves one focused design problem in days. The Monthly Design Partnership is $3,500 a month for 80+ hours, with unlimited requests, turnarounds of 1 to 2 days, and a weekly strategy call.
Most tasks on the monthly partnership come back within 1 to 2 days. A Design Sprint delivers a finished outcome in days rather than months, against a deadline you agree upfront.
Yes. I designed the loan management system for TradeiX, a blockchain supply chain trade finance platform built on the Marco Polo Network, including maker-checker approval flows and paperless eSign settlement. It was adopted by financial institutions including Mitsubishi Bank. I've also designed enterprise billing and invoicing platforms and business intelligence tooling.
Yes. I led the design team on Exsited, an enterprise billing and invoicing platform now serving 35+ enterprise clients, setting the design direction and owning the design system. I've also led a design team through sprint planning and hiring, helping grow a product team from 5 to 12 people.

I only take on a small number of founder projects alongside my AD Group role, specifically so response times stay fast: expect a reply within 2-3 hours, even during active engagements. If capacity is genuinely full, I'll tell you upfront rather than let a project stall.
Yes. Mention it on the strategy call or by email and I'll send one over before we get into specifics.
Tell me what you are building and where it gets complicated. Thirty minutes is usually enough to find the real problem.
