Interested Work Scope

I am looking for a Mid-Level Full Stack role where I can focus on building and shipping products. I am an AI-augmented developer—I heavily leverage tools like Cursor, Claude Code, and Gemini to accelerate development, allowing me to ship complex full-stack applications (like Next.js/Cloud architectures) much faster than traditional workflows.

My background is unique: I have the discipline from 4 years of maintaining legacy systems at Sanlam (MIP), combined with the velocity of a founder who built a multi-cloud SaaS (Visaflow) from scratch.

I thrive in environments that value output and problem-solving over rote memorization. I want to join a forward-thinking team where I can continue to learn, refine my core engineering skills, and use my "speed-first" approach to deliver value.
