About the person who will actually build your software
Why "best" in Bangladesh rarely means biggest
People often search for the "best custom software development company in Bangladesh" right after a bad experience. A 12-person agency promised a CRM. It sent a junior who copied a YouTube tutorial and missed the deadline by four months. Then it asked for another lakh to fix the bugs it created.
The kind of "best" that solves that problem is not a bigger company. It is a senior who owns the work from start to finish. It is someone who answers their own phone when something breaks.
I am RH Fardin, a solo senior developer. For about 5 years, I have built custom business software for BD companies. That includes stock systems for distributors in Old Dhaka and booking and ledger software for clinics in Chattogram. It includes internal dashboards for trading houses and custom CRM and quoting tools for B2B service firms.
I have also built school admission and fee systems, multi-branch POS, and restaurant order screens that work with bKash and Nagad merchant accounts. I scope, design, code, test and deploy every project myself.
In practice, "best" looks boring and specific. You get one WhatsApp number that I actually pick up. You get a written scope before money changes hands, so we both know what "done" means. You get the source code, the database, the hosting logins and the deployment steps.
You could hire any other developer in Bangladesh to take over tomorrow. They will understand what they are looking at, because I write code for the next person, not to lock you in.
Here is the honest trade-off. I am one person, so I take on only a few custom builds at a time, and I will not pretend otherwise. If you want a 30-person team that sends you weekly slide decks, I am not the right fit. But maybe you want the senior who writes the code to be the person you talk to. That is the setup most BD founders quietly wish they had the first time.
