In this episode of Software People Stories, I speak with Mario Lewis, a manufacturing specialist turned IT expert with over 35 years of experience. He talks about his career that began far away from software—in mechanical engineering, manufacturing, operations, and quality—and eventually found its way into the software services world. We talk about what manufacturing can teach software teams, why domain knowledge and business understanding matter, how to stay adaptable through career transitions, and Mario’s experiment with AI-assisted software development through Project Klyve. It’s a thoughtful conversation about learning, reinvention, and doing meaningful work—even when the path is unexpected.

Highlights from this conversation:

• Early passion for aviation led to mechanical engineering, manufacturing, and operations research.
• Manufacturing taught lessons in process rigor, quality, planning, and business constraints.
• Software became a chosen path, not a passion, but Mario approached it with discipline and curiosity.
• Adaptability emerges as a key career skill across industries and eras of change.
• Mario argues that technology is an enabler; real value comes from solving business problems.
• Domain depth and tacit knowledge are becoming more important, especially in GCC-style models.
• Project Klyve tested how far AI and agentic tools could go in building a complete application.
• Advice for early-career professionals: master fundamentals, understand hardware, networks, data, and security.
• Advice for mid-career professionals: keep learning, build domain depth, and understand market forces.
• Retirement feels comfortable because IT was meaningful work, but not Mario’s core passion.

Mario began his career on the shop floor with planning and manufacturing optimization roles in machine tool and switchgear manufacturing. That early focus on physical manufacturing and basic operations grounded his transition into IT services and enterprise software, where he spent over 35 years leading delivery, consulting, operations and business teams. Along the way, in 2006, he authored a book on the realities of IT service offshoring based on his practical experience in the field.

At the end of 2024, Mario stepped away from full-time corporate roles into retirement. He spent that time building Klyve, an automated desktop software factory that implemented an SDLC to build full software applications using agentic AI. It was built around strict engineering controls, deterministic design, and local data privacy.

For Mario, managing career shifts comes down to fundamentals. Staying useful across changing industries requires an openness to lifelong learning, disciplined routine, steady execution, and personal standards while tracking industry and technology trends."
