Jaskaran Singh

Hi, my name is

JASKARAN SINGH.

I'm a software developer passionate about backend engineering and cloud technologies, currently based in India.

About Me

Hello! I'm Jaskaran Singh, a passionate Backend Engineer focused on building cloud-native applications and scalable distributed systems. I specialize in designing and deploying resilient backend architectures on AWS.

Proficient in Java and Spring Boot, I develop robust APIs and microservices that drive seamless user experiences. I'm currently engineering solutions at BeRown, where we’re redefining creative collaboration through technology.

I believe in "Simple solutions to complex problems" — an approach that shapes how I code, design systems, and approach challenges. Outside of work, I stay sharp and inspired by:

  • Solving LeetCode problems to enhance my DSA proficiency
  • Experimenting with emerging AWS technologies and best practices
  • Sharing my learnings through technical blogs and tutorials
  • Powerlifting to maintain a healthy mind-body balance

I’m always eager to connect with developers, startups, and tech communities. If you're passionate about system design, backend innovation, or cloud architecture — let’s build something extraordinary together!
