Hi, I’m Nazmus Sakib.Backend & full-stackengineer.

I build complete web products that hold up in production: NestJS and Django backends with real authentication, Next.js front ends, and AI document pipelines you can audit. At EduApplify I lead a team of four, with two products live today.

Selected work

Three systems. Two built end to end, one led.

Two are live and public. Each one opens into a full case study with the numbers behind it.

BRCULiveHigher education / conference operations

Delegate operations platform for an international conference

University representatives and government officials fly into China for one conference. Every one needs a visa invitation letter, a hotel, a transfer and a badge, tracked across five desks at once.

  • 281 endpoints, a 50-table schema and 38 migrations applied to a live database
  • Invitation letters rendered to PDF on demand through headless Chromium, each with its own QR code
  • Two-layer permissions and refresh-token rotation with instant revocation
  • NestJS 11
  • TypeScript
  • PostgreSQL 16
  • Prisma 7
  • Next.js 16
  • Puppeteer
  • Google Gemini
pre-launch
EDU

Launching soon. The case study covers how it works.

  • Django 6
  • Django REST Framework
  • PostgreSQL
  • Celery
EDUPre-launchStudy-abroad / document automation

AI application pipeline for a study-abroad agency

An agency sending students to Chinese universities retyped the same passport, transcript and funding details into a different portal for every university. This reads the documents and fills the forms, and shows its working.

  • Two-pass Gemini extraction: research with search grounding, then re-verify every value against the source document
  • Six provenance labels, so a reviewer can see which values were read and which were inferred
  • Cancellable, reversible runs on a platform carrying 1,472 automated tests
  • Django 6
  • Django REST Framework
  • PostgreSQL
  • Celery
  • Redis
  • Google Gemini
  • Next.js 16
CBECEALiveNon-profit association / education

Bilingual site and CMS for an education association

An association connecting Chinese and Bangladeshi universities needed its whole site in English and Chinese, edited by staff with no developer. I built it end to end, then ran a full security hardening pass on the live system.

  • Every security finding from a 68-item audit closed on the live system, with 18 of 18 write routes guarded
  • English and Chinese content stored as pairs in one write, so the two languages cannot drift apart
  • 174 translation keys kept identical in both locales, checked by a script
  • Next.js 16
  • TypeScript
  • MongoDB
  • Auth.js
  • sharp
  • nginx
  • PM2
Services

What I can build for you

A fixed price for a fixed scope, agreed in writing before anything starts.Full packages and terms →

Backend & API build

Start here

A production service with the parts that usually get skipped: real authentication, a migration path, and documentation your frontend team can work from.

  • NestJS or Django REST service, your choice of Postgres or MongoDB
  • Authentication with refresh rotation and token revocation
  • Role and permission model scoped to your actual org structure
from$1,5003–5 weeks
Enquire →

Document-to-data pipeline

Turn passports, forms, invoices or transcripts into structured data you can audit. Every extracted value carries a provenance label so you can tell what the model inferred and what it read.

  • Structured-output extraction against a schema you approve
  • Provenance on every field: read, inferred, researched or reconstructed
  • Graceful degradation to manual entry at every failure boundary
from$2,2003–6 weeks
Enquire →

Full product build

A complete web product, front to back, built by one person so nothing is lost between a frontend team and a backend team.

  • Next.js App Router frontend
  • NestJS or Django backend with the auth and permission work above
  • Admin interface for the people who will run it
from$4,5006–10 weeks
Enquire →

Care plan

Keeping something running after it ships. Patching, backups, monitoring and small changes, sold by the month and cancellable with 30 days notice.

  • Dependency and security patching, monthly
  • Backups with a restore actually tested each quarter
  • Uptime and error monitoring with a written monthly report
from$250/monthRolling, 30 days notice

How I work

A clear process, from first call to handover.

  1. 1ScopeA call, then a written scope with a fixed price and a date. Free.
  2. 2Deposit40% to start. The scope document is the contract.
  3. 3BuildA written update every week. You always know where it is.
  4. 4ReviewTwo rounds of revision inside the agreed scope, at no cost.
  5. 5HandoverCode, credentials, and a runbook. You own all of it on final payment.

Scope in writing, before anything starts

You get a written scope with a fixed price and a date. That document is the contract, and it does not quietly move.

A written update every week

Every week you get a written update: what shipped, what is next, and anything that needs your decision.

You own everything

Code, credentials and a written runbook, handed over on final payment. No lock-in, no surprises.

Straight answers, early

If a date needs to move you hear it from me first, in writing, well before the deadline.

Security is part of the build

Real authentication, guarded write routes, rate limiting and security headers on every project, not as an extra.

Numbers you can check

Every project figure on this site is measured from git. Ask for the command and I will send it.

About

Engineer, team lead, builder of complete products.

I am MD Nazmus Sakib, a backend-leaning full-stack engineer from Rangpur, Bangladesh. At EduApplify I was one of three founding developers and now lead a team of four: I plan the projects, review what ships, and write a large share of the code myself.

I like owning a system end to end: the schema, the authentication, the migrations, the deployment runbook. I have built production auth and permission systems four separate times and AI document-extraction pipelines twice. If it has to hold up with real users and real data, that is the work I want.

    Software Developer · EduApplify

    One of three founding developers at a startup now six people strong. I lead the other four developers across three products, own the architecture and code review, and write the largest share of the code.

    • Built the backend of an international conference platform end to end: 281 endpoints, a 50-table schema, and 38 migrations applied to a live database.
    • Sole author of a two-pass Gemini document-extraction pipeline where every value carries a provenance label.
    • Ran a 68-finding audit on a live production site, closed every security finding, and verified 18 of 18 write routes guarded.
    • Shipped a complete customer build in nine days: 39 commits across 191 files.
