Software Development in Kolkata
Kolkata is one of India's most established technology hubs, with a deep pool of engineering talent drawn from institutions like IIT Kharagpur, Jadavpur University, and Presidency University. RJS Tech has been part of this ecosystem since 2001 — long before the city's current tech boom.
Our Topsia office serves clients across Kolkata and beyond, providing custom software development, AI-powered automation, AWS infrastructure management, and eCommerce backend systems. We have delivered projects for clients in fintech, logistics, healthcare, and retail — many based right here in West Bengal.
If you are a Kolkata-based business looking for a reliable software development partner with two decades of local experience, we would love to talk.
