About Me

I'm a Software Engineer with 7+ years of experience, and I've learned that the best software comes from deeply understanding the problem you're solving—not just jumping straight to code.

My approach is straightforward: I listen first. What are you trying to achieve? Who are your users and what challenges do they face? What does success look like for your business? Once I understand the context, I can recommend the right technical solution—whether that's a web app with React and Golang backend, a React Native mobile app, an AI-powered feature, or cloud infrastructure on AWS.I focus on solving the right problem with the right technology, not just implementing features.

Early in my career, I launched a web development and hosting venture (NTL Host) while completing my Computer Science degree. Though I eventually closed it to focus on professional roles with established companies, that experience taught me invaluable lessons about client communication, project management, and the business side of software development. Since then, I've grown significantly through roles at BJIT, WERIT, and Halcyon, becoming AWS certified and building expertise across the full stack (React, Node.js, Golang, Laravel). I'm comfortable working solo or leading development teams, and I bring both technical depth and practical business understanding to every project.

What Sets Me Apart

Problem-first mindset: Understanding user needs and business goals before proposing technical solutions
Strategic thinker: Focus on building the right thing, not just building things fast
Early entrepreneurial experience: Gained practical client management and business skills through an early career venture
Full-stack versatility: Proficient in React, Next.js, Node.js, Golang, and Laravel—choosing the right tool for each problem
End-to-end ownership: From requirements discovery through production deployment and continuous optimization

Areas of Expertise

Problem Discovery & Solution Design

Before writing code, I help you understand what problem you're really solving. Through user research and requirements analysis, we identify what users need, define clear goals, and design solutions that address root causes—not just symptoms.
