About
Building Resilient
Infrastructure
I'm Jishin A V, an energy-driven IT professional with over 13 years of experience in System & Network Administration, Cloud Computing, and Hardware Engineering. My career spans diverse industries — healthcare, digital currency, IT services — where I've built, secured, and optimized infrastructures that empower businesses to scale confidently.
As a CCNA and RHCE holder with an MBA in IT, I bring deep technical expertise with a strategic problem-solving mindset. I thrive on troubleshooting complex systems, designing modular workflows, and ensuring secure, scalable enterprise solutions.
A notable career highlight includes leading a 6-month HIS & LIS software implementation onsite in Saudi Arabia, independently managing configuration and installation for hospitals — covering HIS, HMS, HRMS, and LIS platforms.
Currently pursuing advanced AWS certifications and mentoring teams in cloud, DevOps, and infrastructure automation. My guiding principle: every system — technical or human — can be optimized with clarity, modularity, and resilience.
