About

Shirsendu

I began my journey in tech back in 2008 — not with web development, but by working in network engineering and system administration. Those early roles taught me how systems behave, how they fail, recover, and scale — and that foundation still guides my approach today.

Driven by my primary interest in software development, I transitioned into web development. I worked across several roles — web developer, software analyst, and eventually team manager. I handled everything from client-server applications to cross-platform APIs on Windows and Linux. Along the way, I saw a recurring pattern: copy-paste development, outdated processes, rigid client policies, and internal politics that left little room for original or fresh ideas. Most companies just wanted to “get the job done” no matter how outdated or uninspired the solution was.

So in 2014, I stepped away from that cycle and started “freelancing”. But I quickly realized that going solo wasn’t enough. It was difficult to get better projects from big companies due to concerns around reliability and trust. Meanwhile, outsourcing to so-called “full stack developers” often led to a lack of specialization, poor communication, missed deadlines, and inconsistent quality.

That’s when I started forming a team.

By 2015, I began bringing together a group of like-minded professionals, and in 2017, I officially launched SD TEAM — a boutique web solution agency specializing in web development in Kolkata, built on collaboration, creativity, and accountability..

Today, my team and I deliver end-to-end digital solutions — from branding and websites to mobile apps, business software, and online promotion. We work as a unified team, each of us focusing on what we do best, to provide practical, scalable, and creative solutions for businesses.

In this wonderful journey, we have get in touch with many clients, IT professionals and creative thinkers, who have helped us a lot to learn many things Specially, rational thinking between people and software. we are thankful to all of them, without their help this will never be possible.

At Shirsendu & Team, the premier web design company in Kolkata, India, we don’t just finish projects — we solve problems and build long-term partnerships. I believe real success comes when skill meets sincerity — and that’s the foundation of everything we do at SD TEAM.

FAQS

We generally take 50% advance on the agreed amount and rest 50% before delivery. However, it varies case to case. For medium to large projects, we divide the total amount into multiple parts based on progress of work.

YES! we do build custom Web based business applications. Till now we have delivered 20+ such type of apps which are still working with highest customer satisfaction.

In case of buying a webspace/hosting for your website you must consult with your web developer before you buy anything. A hosting server provides basic functionalities to run your web scripts. If you buy such a hosting which does not support the script you need to run, you are basically wasting your money. Also note that developing a website needs some time, in general most web developers / companies do work on their own server until development finishes so you can save a few bugs until your website is not fully developed. Also in a few cases your development company can offer free hosting with website development. But in this case you must understand their policy carefully so it should not be troublesome for you in future.

Hosted web solutions providers are generally a larger company than Custom Website development companies / freelancers. They do very good promotions of their products, they offer discounts/ free tenures to trap customers.  Generally they attract people by saying “It’s cheap and easy” However ultimately they charge a lot more than custom development and it is not as easy as you show in promotional videos. More than that they have few hounders ready templates. You have to choose one of them, and the only thing you can change is text and images, colors etc.. You have no options to use your own layouts you have in mind. Thay will add charges for using different functionality every month. They will take additional commission for every transaction and you can only use plugins/payment gateway they provide /tie up with them. They can remove features/ functionalities /payment gateways anytime based on their policy.

  • Sometimes  some people suggest buying a domain name similar to your product and/ or service, they think it is good for SEO. But the concept is very old. Nodays SEO does not work on such an algorithm. See our domain name  “SHIRSENDU.COM” nowhere it is mentioned any service we provide, still it comes in the first page of the search engine. So in my opinion it is always preferable to buy a domain which is easy to pronounce, easy to spell, easy to remember. 
  • Re. places to buy domains you must check renewal price for the domain not the first time price, most of the domain providers give very low cost at first time to catch customers. They also offer some additional things with domain names, don't buy them without consulting with your website developer. 
  • In many cases the development company or developer/s may offer a free domain. But I will always suggest not to accept such offers as it might be troublesome for you in future.
