A web app is not a brochure site. It has logins, data, payments and logic - so who actually writes that code matters.
I build custom web applications for Khulna businesses: admin dashboards, booking systems, inventory and order management, customer portals, internal tools. One senior operator designs the database, writes the backend and ships it - the same person you talk to is the person typing the code. No agency layer passing your project to whoever is free.

Trusted by teams I've built websites for
Most Khulna business owners come to me after a static website stopped being enough. The shop on Khan Jahan Ali Road now takes 40 orders a day in a WhatsApp group and a paper khata, and somebody has to manually tally bKash payments every night. The coaching center in Sonadanga is tracking 300 students in an Excel file three people edit at once. That's the moment a website turns into a web application: you stop showing information and start running operations on it.
That distinction changes everything about who should build it. A landing page is forgiving - if the layout breaks, you fix the CSS. A web app has a database, user roles, payment state, and logic that has to be correct, because a bug doesn't look ugly, it loses money or double-books a slot. This is exactly where the typical agency model fails: the salesperson who promised you the moon is not the person writing your authentication code, and the junior who inherited your project at 11pm has never met you.
I work the opposite way. I design the data model, write the backend, build the interface, wire up bKash or Nagad, and deploy it - personally, end to end. When you message me about a bug, you're messaging the person who wrote that exact function. There's no ticket queue and no 'let me check with the dev team,' because I am the dev team. For a web app, where small mistakes compound, that single point of accountability is worth more than a big logo.
Roughly five years of building this kind of software has taught me what Khulna buyers actually need versus what they get sold. You don't need a bloated 'enterprise platform' with 80 features you'll never open. You need the 12 screens that run your actual business, built cleanly enough that they keep working when you have 10x the data - and built so the next change is cheap instead of a rewrite.
These aren't generic selling points. Each one is a specific reason a web application - not a website - is safer in the hands of one senior developer.
The person who scopes your app is the person who writes its database and backend. Nothing gets relayed through a junior, so the logic that runs your business is built right the first time.
bKash and Nagad integration where the payment status, not just a screenshot, drives your order flow. Your dashboard knows what's actually paid so you stop reconciling transactions by hand every night.
Custom panels built around how you actually work - orders, stock, students, bookings, staff roles. Not a bought template you bend your business to fit.
A data model that holds up when 200 records become 20,000. I plan the structure first so growth means adding rows, not paying for a rebuild in a year.
Your staff and customers in Khulna are on phones, often on patchy data. Every screen is built to be usable and fast on a mid-range Android, not just on your laptop.
You approve the full design before development starts - my design-approval guarantee. No 'this isn't what I imagined' after the code is already written and paid for.
Here's the part most companies in Khulna won't tell you straight: not every project that sounds like a 'web app' needs custom software. My tiers start at 50,000 BDT, then 90,000, then 1,50,000 BDT - and that range covers a huge amount: a polished site with a working admin login, a booking or enquiry system, a simple inventory or order tracker, bKash/Nagad collection. If your real need is 'let customers book and let me see the bookings,' you are likely in this band, and quoting you three lakh for it would be dishonest.
Genuinely custom web application development - multi-role systems, complex business logic, a portal your customers log into daily, integrations with other software - starts from 3,00,000 BDT, and that floor is honest too: that kind of build is weeks of database design, backend work and testing by one experienced developer, not a weekend job. When you tell me what your business actually does, I'll tell you which side of that line you're on before you pay anything. The 'koto taka' answer is a real number tied to real scope, with 50% advance and 50% on launch, so you're never funding work you haven't seen.

Straight answers to what Khulna owners ask before commissioning a web app.
It depends entirely on whether you need an app or a strong website with admin features. My tiers are 50,000 / 90,000 / 1,50,000 BDT, which covers booking systems, order trackers, simple inventory and bKash/Nagad collection. Genuinely custom software - multi-role portals, complex logic, integrations - starts from 3,00,000 BDT. I quote a real number after I understand your scope, never a guess.
A website shows information; a web application does work with it. Logins, a database, user roles, payment status, dashboards, automated logic - that's an app. If your staff currently runs the business in Excel, WhatsApp groups or a paper khata, you've outgrown a website and you're describing an application.
Yes - and properly, where the payment status drives your order or booking flow, not just a screenshot a customer uploads. Your dashboard shows what's genuinely paid, pending or failed, so you stop manually reconciling transactions at the end of every day.
Me, directly. I design the database, write the backend, build the interface and deploy it personally. For a web app that runs your operations, one senior person who owns the whole thing end to end is far safer than an agency handing your code to whoever is free that week.
Admin dashboards, booking and appointment systems, inventory and order management, customer or student portals, internal staff tools, and sites with real backend logic. Common locally: shops moving off WhatsApp-and-khata ordering, coaching centers managing students, and service businesses taking bookings online.
Timeline depends on scope - a booking system is a different job from a multi-role portal, and I'll give you a real estimate after we scope it. Payment is always 50% advance to start and 50% on launch. Before any development begins, you approve the full design under my design-approval guarantee, so you're never surprised by what gets built.
