Services

Custom software & SaaS development

We take products from idea to paying users — discovery, design, build, launch, and the boring-but-vital operating work after. Fixed scope, weekly demos, code you own.

Fit

Who this is for

Founders with a validated idea

You know the problem and the customer. You need a team that can turn a one-page brief into a product people pay for — without burning the runway on rewrites.

Businesses drowning in manual work

Spreadsheets, WhatsApp threads, and copy-paste holding your operation together. We replace the duct tape with software shaped around how you actually work.

Teams replacing a legacy system

The old system works, barely, and everyone is afraid to touch it. We migrate carefully: data intact, staff retrained, no big-bang cutover.

Scope

What's included

Product discovery & scoping

Structured workshops that turn your idea into a written scope: user flows, feature list, what's out (as important as what's in), price, and timeline.

UI/UX design

Wireframes first, then high-fidelity screens in Figma. You click through a prototype before we build, so changes cost minutes, not sprints.

Full-stack engineering

TypeScript end-to-end: Next.js frontends, NestJS APIs, PostgreSQL data. The same stack running our own products in production.

Payments & billing

Subscriptions, one-off payments, invoices, and local gateways — bKash, Nagad, SSLCommerz — alongside cards and Stripe where markets need them.

Admin panels & dashboards

The unglamorous half of every product: role-based admin tools your team will use daily, built with the same care as the customer-facing side.

Quality & testing

Automated tests on the paths that matter — auth, money, data integrity — plus staging environments and review before anything reaches users.

Launch & handover

Deployment, monitoring, backups, documentation, and a recorded walkthrough. You own the code and the accounts from day one.

Approach

How we approach it

  1. 01

    MVP means smallest complete product

    We cut scope, not corners. Version one does less, but everything it does works — auth, payments, and edge cases included.

  2. 02

    Weekly working software

    Every week you get a staging link with real progress, not a slide deck. Course-correcting in week two beats discovering a mismatch in month three.

  3. 03

    Build for the second year

    Migrations, seed data, logging, feature flags — decisions that cost little now and save you a rewrite when the product grows.

  4. 04

    One senior owner

    A single senior engineer owns your build end-to-end and talks to you directly. Context never gets lost in a handoff chain.
