“To empower small and growing businesses with world-class web and marketing solutions — without the complexity, confusion, or cost of big agencies.”
My goal isn’t just to deliver code or graphics — it’s to solve real problems, enhance user experience, increase visibility, and maximize ROI for my clients.
Hi, I’m Shirsendu Das, the founder (CEO) and lead strategist behind Shirsendu & Team (SD Team) — a full-stack web development company based in Kolkata, India, offering end-to-end digital solutions tailored for today’s evolving business landscape.
My journey began not in design or code, but in network engineering and system administration, where I learned how digital systems operate, scale, and recover under real-world conditions. That technical foundation continues to shape my approach to problem-solving — practical, resilient, and deeply human-centric..
With over 15 years of hands-on experience, I’ve collaborated with startups, SMEs, entrepreneurs, and global clients to transform ideas into high-performance platforms. Whether it’s custom web application development in Kolkata, eCommerce website design, mobile apps, or online marketing services, my mission has always been clear: to simplify technology and make it work for people — not the other way around.
