Many businesses sign an R&D tax adviser's contract without knowing how the fee really works. KnowYourFees.org (https://KnowYourFees.org) explains it in plain English, so they can compare proposals before they sign.
What I built
→ An interactive calculator that compares a percentage fee with a fixed fee as you change the claim size, and shows where they cost the same
→ A five-minute fee test that people answer with their own proposal in front of them
→ Guides on fee types, red flags, engagement letters and 20 questions to ask an adviser
→ Country pages for the US, UK, Ireland, Canada, Australia, New Zealand and Singapore
→ Built with Laravel, Vue and Inertia with server-side rendering, so every guide page loads fast and is easy for search engines to read

If you need a content-heavy website with interactive tools like calculators or quizzes, I'd be happy to talk about it.

Booking a tutor shouldn't take 6 emails. So I built Mahogo, a live lesson booking platform where students find a teacher, pick an open slot and book in a few clicks.
What's inside
→ Teachers set their own availability, students book open slots instantly
→ Subscription plans that give students lesson tickets, with priority booking
→ Live lessons run over Zoom, with a calendar of every booked, completed and cancelled session
→ Student dashboard with tickets left, upcoming lessons and subscription management
→ Admin panel to manage users, roles, permissions and subscription plans
Built with Laravel, PHP and MySQL.
Running a tutoring, coaching, fitness or consulting business that still books by email or WhatsApp? I can build you a booking platform like this. DM me or comment "booking" and I'll share how it would work for you.

TaxTrex.ai: website for an AI-powered R&D tax credit platform for CPAs
I built the marketing website for TaxTrex, software that helps accounting firms prepare R&D tax credit claims in-house.
→ Multi-country setup with separate subsites (US, Australia, Canada and more) and a country switcher in the header
→ Clear 3-step product story, features, pricing, training and knowledge center pages
→ Lead capture built in: Book a Call, Enroll Now and live chat
→ Fast, responsive build that keeps a content-heavy site easy to navigate

AusGrant: a global R&D grants index across 13 countries
I built ausgrant.com, a funding directory that helps businesses find open research & development grants by country.
→ 13 country directories, each with its own local programmes, currency and language version
→ 4,000+ indexed grant programmes with amount, deadline, eligibility and the official application link
→ National, state and EU funding in one place, re-verified weekly
→ Clean, data-heavy UI that stays easy to scan on desktop and mobile
