A working web app built around your real workflow — not a template, not a half-finished prototype handed off to a junior.
I am RH Fardin, the developer who plans the data model, writes the code, wires the payments, and ships the live build. Web application development service in BD for founders, operations teams and SMEs who need a custom internal tool, customer portal or SaaS product that runs reliably without a 12-person agency wrapped around it.
Solo senior operator. Around 5 years building for Bangladesh businesses. Custom web app builds start from 3,00,000 BDT. Fixed scope, 50% advance and 50% on launch, design approval before any code is shipped to production.
+Trusted by 50+ founders, agencies and teams across Bangladesh and beyond.
Trusted by teams I've built websites for
Most BD founders I meet have already paid for a web app once. They got a flashy slide deck, an upfront invoice, three months of "phase 1" silence, and a half-working admin panel that nobody on the team trusts. The dev shop blames the client; the client blames the dev shop; the app sits unused while the team goes back to Excel and WhatsApp. That is the gap this service exists to close.
A web application is not a brochure site with extra pages. It is a piece of software that handles your data — orders, students, patients, members, drivers, invoices, leads — and that you have to live with for years. So the work that matters happens before any pixel is drawn: mapping the actual workflow, naming who logs in and what they should see, deciding what the database stores, what bKash or Nagad needs to confirm, what gets emailed, what gets logged, and what happens when the internet drops mid-checkout in Cox's Bazar.
I run that scoping conversation with you directly. No account manager translating, no junior taking notes. By the end of the discovery call you have a written scope, a fixed price, a delivery date and a clear answer to "what is in version 1 and what is not." Then I design, build, test, deploy and hand over — same person across the whole timeline. If something breaks at 11 PM the day after launch, you message me, not a ticketing system.
Service scope covers admin dashboards, multi-role portals, booking and reservation tools, school and clinic management systems, internal CRMs, inventory and POS web apps, membership platforms, and lightweight SaaS MVPs. Built on a modern stack (Laravel/Node/Next.js depending on fit) hosted on infrastructure that handles Bangladesh traffic patterns — including the 8 PM mobile spike — without falling over.
Six things this service does differently from the typical "software house" experience in Bangladesh.
Before any code, we walk through every user role, every screen, every status change, every payment path. You sign off on a written scope — no "we'll figure that out later" surprises in month two.
Custom web app builds start from 3,00,000 BDT with 50% advance and 50% on launch. The number you sign is the number you pay. Out-of-scope work gets a separate quote, in writing, before it starts.
Live payment integration with proper transaction logs, refund handling and webhook reconciliation — not a manual "send screenshot of payment" workaround that breaks the moment volume picks up.
Admin, manager, staff, customer, vendor — each role sees only what they should. Audit logs on sensitive actions. Password reset, 2FA on admin accounts and session control built in from day one.
Built mobile-first because 80%+ of your users are on mid-range Androids on patchy networks. Forms that save drafts, pages under 200KB, graceful failure on bad connections — tested on real devices, not just Chrome dev tools.
Source code in your GitHub, database on a server in your name, domain in your account, deployment keys handed over. If you ever switch developers, nothing is held hostage.
This service is the right fit if you have an operational problem you can describe in plain Bangla or English: "my team is managing 400 student admissions in Google Sheets and it is collapsing," "my distributors keep calling for stock and I need a portal," "I want to take service bookings online with bKash payment, not over Messenger," "we have a SaaS idea for the BD market and need a working MVP to show investors." If you can name the pain in one sentence, we can scope a build in one call.
It is not the right fit if you need a 50-person enterprise system, a hospital-grade EMR with regulatory certification, or a real-time trading platform — those need a multi-developer team with a QA function I cannot personally run as a one-person operation. I will tell you that on the first call and point you toward someone better suited rather than take the project and underdeliver. The same honesty applies to budget: if your real budget is 80,000 BDT, a custom web application is not the answer, and I will say so. A brochure website with a contact form might solve 90% of what you actually need.

Real questions BD founders ask before commissioning a custom web app.
Custom web applications start from 3,00,000 BDT. That is the floor for a real multi-role system with database, authentication, payment integration and admin panel. Most builds land between 3,00,000 and 8,00,000 BDT depending on the number of user roles, custom workflows and integrations. Payment is 50% advance and 50% on production launch. Simpler builds that fit my standard website tiers (50,000 / 90,000 / 1,50,000 BDT) are for sites with content and a contact form — not for apps that handle live transactions.
A focused MVP with 2-3 user roles and bKash payment usually takes 8-12 weeks from advance to live launch. A larger multi-portal system runs 12-20 weeks. I give you a written timeline in the scope document with milestone dates — discovery sign-off, design approval, alpha build, beta with your team, production launch — so you always know exactly where the project is.
You own everything. Source code goes into your GitHub or GitLab account. The server, domain and hosting are billed to you and registered in your name. I get deploy access for the duration of the project and any maintenance retainer. If we ever part ways, nothing is locked behind my login — that is non-negotiable on my side too because I do not want to be the single point of failure for your business.
Yes. I have built live integrations with bKash Tokenized Checkout, Nagad and SSLCommerz (which covers Rocket, Upay, Visa, Mastercard, AmEx, internet banking and mobile banking in one). The integration includes webhook reconciliation, refund handling and a proper transaction log in your admin panel — not a screenshot-based manual flow.
After production launch you get 30 days of free fixes for anything that does not behave as the scope document said it should. After that, ongoing work is on a maintenance retainer (monthly or pay-as-you-go) — bug fixes, feature additions, server upkeep, security patches. Roughly half my clients keep me on a small retainer for the first 6-12 months while the system beds in, then move to pay-as-you-go.
Yes. I will set up the production server (typically DigitalOcean or Hetzner for Bangladesh-friendly latency and pricing), configure backups, SSL, monitoring and the deploy pipeline, and document it in plain language so any future developer can take over. Hosting is billed directly to you so there is no markup and no dependence — but I run the technical side as part of the maintenance retainer if you prefer not to think about it.
