Career break

Personal goal pursuit

May 2017 – Dec 2021 · 4 yrs 7 mos · Delhi

  • During this period, I immersed myself in the interdisciplinary learning journey of the UPSC Civil Services Examination — one of the most competitive exams in India. This phase helped me develop a well-rounded understanding of topics like:
  • Indian Polity, Constitution & Governance
  • Economics, Ethics, and International Relations
  • Current Affairs, Decision Making & Logical Reasoning
  • Through this, I honed several transferable skills that continue to empower me in software engineering today:
  • Analytical Thinking – breaking down complex systems (much like system design)
  • Effective Research – diving deep into unfamiliar domains quickly
  • Clear Communication – explaining intricate ideas simply
  • Discipline & Resilience – managing large information volumes under time pressure
  • This was not a break, but an intentional learning phase that helped me sharpen my thinking, and today, I bring this same mindset to building scalable products and solving engineering problems with clarity and purpose.
