Senior Frontend Developer
Senior frontend developer building modern web experiences.
I design and build polished frontend experiences for brands that want stronger presence, clearer messaging, and better-performing websites.
About
Engineering interfaces that feel obvious for the user and intentional under the hood.
I'm Harry - a Senior Frontend Engineer who believes the best interfaces are the ones users never think twice about. They just work. They feel right. And somewhere underneath all of it, there's a thousand intentional decisions that made it that way.
With over 6 years of professional experience, I've partnered with more than 450 clients - from early-stage startups building their first product to established enterprises modernising their digital infrastructure. Across every engagement, my focus has been the same: close the gap between how something looks and how well it actually works.
My core expertise spans React, JavaScript (ES6+), TypeScript, Tailwind CSS, Node.js, Figma, and Firebase - but beyond the stack, what I bring to a team is the ability to think in systems. I care about component architecture, performance budgets, accessibility, and writing code that the next developer will actually thank you for.
I hold a BSc in Computer Science from the University of Cape Coast (UCC), and I stay sharp through continuous learning - because in this field, last year's best practice is this year's technical debt.
Beyond client work, I build tools that solve real problems - like TaskFlow, an internal notification system I engineered from scratch to keep distributed teams aligned across Email, SMS, and WhatsApp, without the noise of manual follow-ups.
I'm deliberate about the work I take on. Not because I'm selective for the sake of it - but because I'd rather do fewer things exceptionally than many things adequately.
When I'm not shipping code, I'm thinking about product, mentoring developers, or figuring out how to raise the bar for what gets built out of Ghana.

Testimonials
Trusted by clients who care about quality, clarity, and execution.
Feedback from founders, businesses, and ministry teams I've helped with product, websites, and digital delivery.
Harry brought structure and clarity to the entire SharkDeals build. The platform feels fast, clean, and easy to shop through. That directly improved how confidently customers move from browsing to checkout.
Maasentu needed more than a storefront. We needed a platform that reflected the scale of our business, our brands, and the trust customers place in us. Harry delivered that with real attention to detail.
DevRank feels simple in the best way. It loads quickly, the quiz flow is smooth, and it actually makes learning frontend concepts feel engaging instead of overwhelming.
TaskFlow removed a lot of manual follow-up from our internal communication. What used to take multiple reminders now happens automatically, and the team stays aligned with far less noise.
The Prota House website gave our ministry a digital home that feels welcoming, organised, and aligned with who we are. Members and visitors can now find what they need without confusion.
Pneuma Gathering needed a stronger online presence, and Harry helped us achieve exactly that. The website feels modern, clear, and far more aligned with the scale of the ministry.
What stood out was not just the design quality, but the way Harry thinks through usability, structure, and performance before writing code. The result felt finished, not just delivered.
Harry communicates clearly, works with speed, and keeps quality high. That combination made the project process feel structured and professional from the first call to final launch.
Using DevRank has been genuinely helpful. The questions are practical, the interface is clean, and the platform makes it easy to test what you know and spot where you need improvement.
Harry handles work like an engineer and thinks like a product partner. He does not just build screens, he improves the overall experience and helps the project make better business sense.
