Senior AI Engineer & Teacher

As an expert in Artificial Intelligence, specializing in LLMs, I love to teach others AI engineering best practices. With real experience in the field working at big tech, I aim to teach you how to be successful with AI from concept to production. My blog posts are generated from my own video content which is referenced at the end of the post.

When I became a senior engineer building AI solutions at a big tech company, I noticed something striking: the AI field is drowning in hype, with endless discussions about theoretical capabilities and future potential. Meanwhile, businesses struggle desperately to find engineers who can implement practical AI solutions today. I’ve seen this gap firsthand, and it creates a remarkable opportunity for those focusing on real-world implementation—the exact path I followed to condense a decade-long career into just four years.

Moving Past the Hype Cycle

The most valuable AI skills aren’t about understanding esoteric model architectures or debating philosophical implications. In my daily work, I’ve learned that companies need engineers who can:

  • Integrate AI capabilities into existing business processes (what I do when implementing systems used by thousands)
  • Create reliable, maintainable systems that scale appropriately (a skill I’ve mastered through real projects)
  • Manage costs while delivering performance (crucial for production AI that doesn’t break budgets)
  • Deploy solutions that solve actual business problems (the skills that tripled my income)

These practical capabilities are in critically short supply despite the flood of AI content online. I’ve interviewed dozens of candidates who can discuss transformer architecture in detail but struggle to build a simple production system.

The Implementation Advantage

Engineers who develop practical implementation skills command premium salaries because they:

  • Deliver measurable business value rather than interesting demos (I focus on solving real problems)
  • Build systems that operate reliably in production (my solutions run 24/7 serving thousands of users)
  • Understand both technical requirements and business context (how I justify AI investments)
  • Can bridge between AI capabilities and organizational needs (translating hype into reality)

This career path avoids the “perpetual theory trap” where knowledge never translates to practical application. I’ve seen this trap ensnare many brilliant people who never progress beyond fascinating experiments to actual production systems.

Business-Focused Technical Skills

The most in-demand practical skills center on implementation—exactly what I focus on in my daily work:

  • System design that accommodates AI components (understanding tokens, embeddings, and how to structure complete systems)
  • Data pipelines that support model operations (from RAG implementations to vector storage solutions)
  • Monitoring and maintenance of AI systems (ensuring reliability at scale with proper observability)
  • Integration with existing enterprise systems (making AI work within complex organizational environments)

These capabilities directly address the challenges businesses face when attempting to deploy AI solutions. They’re also the exact skills that helped me progress from a self-taught beginner to implementing AI solutions used by thousands of people at scale.
