My journey with technology started with my bachelors in Computer Science. I had got good understanding of Linux Operating Systems and Networking during my stint at College and it paved way for my future specialisations. In my first job - Infosys, developed Products and Platforms on Big Data and later joined my close friends and started Knowledge Lens, after that moved to USA for Masters in Data Science and worked for Siemens in Product Lifecycle Management R&D. Had an opportunity to build IoT platform and mentor interns/new joiners in various aspects of Products & Platform development. In my opinion, Technology is a means to better our day-to-day life events, so my focus is in building Solutions to existing problems. In that respect, I do not contain my self to trending technologies/specific languages or programming styles but look for best technologies that can help build Solutions at per necessitates (Scalable, Resilient, De-couple/Coupled, Cloud/On-Premise, Secured, Cost Effective, Sustainable and Faster operations).
