    Beyond the Code: Lessons That Make You Senior

    A senior engineer reflects on the non-technical skills that define seniority in software development. Key lessons include prioritizing reasoning over rigid rules, verifying assumptions instead of guessing, questioning unexpected positive results, building mechanisms rather than relying on good intentions, learning to say no to protect team complexity, taking ownership of decisions, mentoring through safe failure rather than protection, favoring simplicity over cleverness, preparing for inevitable system failures, and adapting to technological changes like AI tools. The author emphasizes that seniority is about judgment, humility, and growing others rather than just technical mastery.

    Don’t buy GPUs for AI

    GPUs are becoming unnecessary for most AI applications as smaller language models like Mistral 7B and Phi-3 Mini deliver practical results on CPUs. Modern processors, edge devices with NPUs, and cloud rental options provide cost-effective alternatives to expensive GPU ownership. Specialized hardware like TPUs and software optimizations through quantization are making GPUs obsolete for all but the largest model training operations.
