Hello World, my name is

Vaibhav Gharge.

I love working with great people to build products that people love.

A passionate Senior Software Engineer with over 9 years of experience in the development of mission-critical, highly scalable, and robust distributed systems for FinTech startups, multinational banking, and wealth management institutions. Skilled in architecting cloud-based solutions (such as AWS, Azure) and proficient in applying Agile methodologies, including Scrum, Kanban, and TDD.

As a technologist, I'm enthusiastic about working with great people to build products that people love. I had an amazing time building a product that would revolutionize the FX space at M-DAQ.

My passion lies in utilizing the latest AWS cloud technologies to develop serverless domain driven design applications that leverage an event-driven architecture to create highly scalable, resilient systems with low-latency, high availability.

I derive great satisfaction from addressing complex engineering challenges and inspiring teams to create impactful and valuable solutions on a large scale.

I'm constantly in pursuit of knowledge and enjoy exploring emerging technologies, which I like to share with others through my blog.

About Me

As a Senior Software Engineer based in Singapore, I specialize in designing and building cloud-native, serverless fintech products and services, with a proven track record of working in the FinTech industry.

As a truly full-stack engineer, I believe in mastering technologies that improve robustness and productivity, irrespective of their source, and putting them to effective use.

When I'm not coding, you'll find me watching or reading about my favorite astrophysics documentaries and articles, hiking, or lifting weights in the gym.

Here's a few technologies I've been working with recently:

Python
Java 8+/J2EE
AWS Serverless
Spring Core (JPA, SpEL, AOP)
Spring Boot, MVC
Spring WebFlux
Hibernate
