About Me

Hello! I'm Sujit, a passionate technologist based in Pune, India. My journey with computers began during my Civil Engineering days when I fell in love with technology — a love that has only grown stronger over the past 25 years.

During college, I ran a cybercafe that was on the verge of closing — I turned it into the best in town! That's when I learned C/C++ and discovered my knack for both software and hardware. After engineering, I completed my Diploma in Advanced Computing (DAC) from CDAC Pune, where I was exposed to nearly 15 programming languages in just 6 months.

My professional journey has taken me from being a Technical Lead at Better Technology Labs for 10 years, to becoming a Top Rated Freelancer on platforms like Upwork, Codementor, and HackHands, to serving as CTO at a FinTech company. Now, I'm the Founder of StepForward Solutions LLP, where we're building amazing products under the Kaizen Apps brand.

Here are some technologies I've been working with recently:

C# / .NET Core
ASP.NET Web API
Azure / AWS
Elasticsearch / ELK
Kafka / RabbitMQ
WinForms / VSTO
OCR / AI-ML
SQL / Redis
