Senior Frontend Engineer
Building scalable, user friendly and elegant web and mobile applications.
About
I’m a software engineer with over 6 years experience in frontend development. My journey into tech began way back in the university, where I was first introduced to software engineering, I was mind blown at the fact that with a few lines of code I could make my own website and potentially build my own facebook or youtube, I decided to take a deep dive into software development and I havent looked back since.
Looking at my career I’m mostly frontend focused and most of the work I do is on the frontend, but I do have some backend experience as I believe having a bit of full stack knowledge makes for an over all better frontend engineer. One thing about me is that I enjoy building products that people use in their day to day lives and I’m always looking to leverage my expertise and experience to contribute to innovative solutions.
Projects
Rabafast
Rabafast is a multi-currency payment platform for businesses (SMEs and larger companies) to run cross-border payouts. It supports multicurrency wallets, foreign-exchange conversion, and crypto payouts such as USDC. As senior frontend engineer, I spearheaded frontend development and delivered the web dashboard used to manage payments, wallets, and customers.
Dot Business
Dot Business is a business banking platform for businesses to manage their finances. I owned the frontend: the web dashboard teams used to manage finances and customers—UI architecture, performance, and data-heavy views—while backend and platform services were built by other engineers.
Qshelter
Qshelter is a real estate platform that helps users buy homes through direct payment, installment plans, or mortgage. The product spans a public website and an authenticated dashboard; I was brought onto a brownfield codebase to ship version 2 across both: a ground-up revamp of buggy, slow v1 experiences into TypeScript React apps with clearer architecture, stronger performance, and redesigned, mobile-friendly UI.
MailMaker AI
MailMaker AI is a personal project: a web-based visual email template builder so people can ship responsive, client-safe HTML without hand-writing MJML. It compiles MJML in the browser and targets compatibility across major email clients.
Nebula PDF Generator
Nebula PDF Engine is a personal open-source npm library I built: JSX-driven PDF generation with Flexbox-style layout, automatic pagination, and first-class tables, without Headless Chrome. It targets server-side and edge runtimes where a small footprint and predictable layout matter more than shipping a browser binary.
