Khalid Umar

Software Engineer & Founder

I'm a software engineer and the founder of Nutshellbytes. I started building real products before finishing my degree, and my work has since moved from writing features to owning whole systems — understanding the business problem, designing the architecture, shipping it, and keeping it running.

What I care about most is system design: how information moves, what happens when usage grows, which decisions become limitations two years later. I'm most useful on problems where the engineering is larger than the screens.

Work

  • Founder & CEO

    NutshellbytesNow

    My software company. Beyond engineering, I own technical strategy, product decisions, client relationships, hiring and where we spend our resources. Running it taught me that the best technical solution isn't always the best business decision.

  • Technical Lead

    Kappa Hong Kong Ltd

    Technical decision-making and engineering leadership, beyond implementing features.

  • Software Engineer

    Aplash.io

    Hong Kong–based product work on larger systems, moving into architecture and senior technical responsibility.

    Upwork

    International clients across straightforward applications through to complex analytical and business systems. Entering unfamiliar codebases repeatedly is the fastest way I've grown.

Software engineering & architecture
Designing large, reliable systems rather than isolated features.
SaaS & product development
Software that becomes a business, not software built to order.
Artificial intelligence
AI as a component inside larger systems — document understanding, retrieval, automation, agents — not another chat interface.
Entrepreneurship
Building products, teams and companies of my own.
