About

Who I am and how I build

I'm a self-taught software engineer with a founder's mindset and a habit of building systems that usually take whole teams. I work across AI, trading systems, automation, e-commerce and IoT — always with one goal: ship products that actually work in the real world.

I've built AI dialers that coach agents in real time, helping them handle objections, retain difficult customers, and close more sales with sub-100ms responsiveness. These systems auto-generate emails and SMS replies, detect behavioural patterns, and schedule work around agent availability so operations stay smooth while the AI focuses on performance. I also engineer trading systems powered by 18 technical and fundamental indicators, using trained algorithms to surface high-probability setups and enforce disciplined risk management. On the hardware side, I design compact GPS trackers using the REYAX RYS8830 module with EasyEDA-based circuitry, paired with a mobile app for seamless real-time tracking. Fast, precise and relentless, I turn complex ideas into integrated systems that actually run end-to-end in the real world.

Experience

How I've learned to build and sell
Software Engineer
Independent Projects · 2020 – Present
Architecting AI, trading systems, IoT, e-commerce and automation systems end-to-end: from concept and design through to implementation, testing and iteration.
Sales Representative – US Call-Center Campaigns
3 years
High-pressure sales across US campaigns gave me a deep understanding of call-centre operations and customer psychology. That frontline exposure revealed where traditional systems break down and shaped my ability to engineer AI-driven tools that remove inefficiencies, close critical gaps and lift performance across entire operations.
Brand Promoter
2 years
Worked on retail brand activations, including MTN's Springboks campaigns, strengthening my communication skills and sharpening my instinct for building products people naturally engage with.
