WEB APPLICATIONS.
A marketing website tells people about your business. A web application is your business logic, running in a browser — a dashboard, a booking system, a tool your own team logs into every day. Different job, different build. If what you actually need is a public-facing site, see website development instead — we will tell you which one fits before any work starts.
WHAT THIS LOOKS LIKE.
ADMIN DASHBOARDS
Internal tools your ops team uses daily — order management, staff scheduling, approval queues. Built for the people using it eight hours a day, not for a demo.
BOOKING & SCHEDULING
Appointment slots, room bookings, or resource scheduling with real-time availability — the kind of system a clinic, salon, or service business runs on.
MULTI-TENANT SAAS
A product you sell as a subscription to other businesses — with account isolation, billing, and role-based access built in from the start, not bolted on later.
DATA-HEAVY PORTALS
Reporting tools, client portals, or partner dashboards that need to render large tables and filters fast — where a slow admin panel costs your staff real hours.
For technical evaluators
WHY NEXT.JS AND REACT.
If you are evaluating vendors on stack, not just price: every web application we build runs on Next.js and React with a Node.js API layer and PostgreSQL, TypeScript throughout. Here is why that combination specifically, not stack-as-marketing.
Server-rendered by default
Next.js renders on the server first, so a dashboard with real data loads fast even on the mid-range Android phones and inconsistent mobile data most of your team actually uses — not the fibre connection in a demo.
One codebase, typed end to end
TypeScript across the frontend and API layer catches a whole class of bugs before they reach your users — fewer "it worked on my machine" incidents in a system your team depends on daily.
Real-time where it matters
Order boards, live dashboards, and multi-user editing use WebSockets or polling deliberately — not everywhere, because real-time infrastructure has a real cost, and we only add it where the workflow actually needs it.
Built to add features later
A modular route and component structure means adding a new report or workflow six months in does not mean rewriting what already works — a common failure mode of tools built by a single freelancer without this discipline.
Proof, not just claims: our TechLens BD build on this exact stack shipped sub-1.5-second page loads and a 145% increase in organic traffic — real numbers from a real production system, not a benchmark on empty data.
How we work
THE PROCESS.
Typical timeline: 6–10 weeks for a focused internal tool, 3–5 months for a multi-tenant SaaS product. The date we commit to depends as much on how fast feedback and content come back as on how fast we build — we will be straight with you about that in scoping.
- 01
Map the real workflow first
We shadow how the task actually happens today — spreadsheets, WhatsApp, paper — before designing the tool that replaces it. Software that ignores the real workflow gets ignored back.
- 02
Data model before UI
Screens are cheap to change; a wrong data model is not. We agree the entities and relationships in writing before any interface design starts.
- 03
Build in milestones you can log into
You get a working, logged-in build to click through at each stage — with your real data structure, not placeholder text.
- 04
Load-test before handover
For anything with concurrent users — a booking system, a shared dashboard — we test under realistic simultaneous load, not just a single browser tab.
- 05
Handover, with the keys
Code, hosting, and database access go in your name. You are never locked into us to keep the system running.
Common questions
WEB APP FAQ.
[01]What counts as a "web application" versus a website?
A website presents information to the public — a marketing page, a blog, a store. A web application is working software that runs in a browser: an internal dashboard, a booking system, a tool your own team logs into. If you are not sure which you need, tell us the task and we will tell you.
[02]How much does web application development cost in Bangladesh?
Focused internal tools typically start around $3,800. Multi-tenant SaaS products or systems with complex real-time requirements scale from there based on the number of user roles, integrations, and concurrent-use requirements.
[03]Why do you build on Next.js and React specifically?
Server-rendered pages load fast even on the mid-range Android phones and inconsistent mobile data most users in Bangladesh actually have, TypeScript catches bugs before they reach production, and the component structure makes adding features later straightforward rather than a rewrite.
[04]Can you build a multi-tenant SaaS product we sell to other businesses?
Yes — account isolation, subscription billing, and role-based access are built in from the start rather than added after the fact, which is the difference between a real SaaS architecture and a single-customer tool retrofitted later.
[05]What happens after the application launches?
Launch includes an agreed period of post-launch fixes. After that we offer maintenance retainers for updates, monitoring, and small changes so the system stays secure and current.
Working with us from outside Bangladesh
International web application development
Teams outside Bangladesh hire us for the builds this page documents — internal dashboards, booking systems, and multi-tenant SaaS — on the same fixed stack: Next.js and React over a Node.js API and PostgreSQL, TypeScript throughout. The stack is chosen for re-staffing as much as performance: any React shop in your own market can take over the codebase after handover, because code, hosting and database access go in your name.
Overlapping hours, stated plainly
We work from Dhaka on UTC+6. That is a 2–3 hour offset from the UAE, Saudi Arabia and Qatar, and 4 hours from eastern Australia — scheduled calls sit inside both working days without anyone taking a midnight meeting. UK and US sessions are booked into your morning, our evening.
Quoted and invoiced in USD
International projects are priced in USD against published ranges, not converted from a local rate at quote time. Typical band for this service: $3,800+. Scope drives the figure — branch count, integrations and data migration move it most.
You own what we build
Source code and database are yours on final payment, handed over to your own repository. NDAs are signed before technical scoping. We do not resell your build or retain a licence over it.
