Hi, I'm Raisul Islam Likhon

Software engineering student and developer from Bangladesh. I build lightweight, privacy-first apps for Flutter & Android, plus web tools and Python automations that quietly do the boring work.

01 — About me

I like software that stays out of the way.

I'm Likhon — a software engineering student at Daffodil International University in Bangladesh. I got here by taking things apart: first customising Android, then ReVanced patches and bytecode tweaks, and eventually building my own apps instead of only modifying other people's.

Today I build Flutter and native Android apps (Dart & Kotlin, Jetpack Compose, Material 3), web tools and sites (React, TypeScript, plain HTML/CSS/JS) and browser extensions on Manifest V3.

I also write Python automations for the boring parts of student life — like turning messy university routine spreadsheets into clean, structured JSON with pandas and openpyxl.

My rule is simple — small, fast and private. Offline-first where it makes sense, no bloat, no telemetry, no surprises.

02 — Services

What I can build for you

From a first prototype to a signed APK or a deployed site — Flutter, native Android, web, extensions and the automation glue in between. Clean code, clear communication and something you can ship.

01

Flutter Apps

One codebase, a native feel everywhere — cross-platform apps in Flutter & Dart, from idea to signed build.

  • Material 3 design that follows your brand
  • Offline-first storage and cloud backup
  • Rich lists, search, filters and stats screens
  • Signed release APKs built with GitHub Actions
  • Flutter
  • Dart
  • Material 3

02

Native Android

Kotlin & Jetpack Compose apps that stay fast on low-end phones and light on memory.

  • Jetpack Compose with Material You theming
  • Room / SQLite persistence, MVVM architecture
  • WebView, media session & background work
  • Play-Store-ready builds with CI/CD
  • Kotlin
  • Compose
  • Room

03

Web Apps & Sites

Fast, responsive websites and single-purpose web tools that look right on every screen.

  • Mobile-first, responsive layouts
  • React + TypeScript, or plain HTML/CSS/JS
  • Forms wired to APIs, Sheets & email
  • Deployed on Vercel, Netlify or GitHub Pages
  • React
  • TypeScript
  • Tailwind

04

Browser Extensions

Manifest V3 extensions for Chromium browsers — content blockers, privacy tools and small useful things.

  • Declarative request filtering & content blocking
  • Local-only storage with WebCrypto encryption
  • Inline autofill, popups & options pages
  • Zero telemetry, no remote scripts, strict CSP
  • Manifest V3
  • WebCrypto
  • JavaScript

05

Python Automation & Scripts

Small command-line programs that kill repetitive work — especially anything that starts with a spreadsheet nobody wants to retype.

  • Excel & CSV parsing with pandas, openpyxl and json
  • Web scraping, data cleanup and formatting
  • JSON, PDF and report generation
  • Scheduled / batch scripts you run with one command
  • Python
  • pandas
  • openpyxl

03 — Automation & data

I automate the boring parts with Python.

A lot of my tooling starts with a spreadsheet somebody has to retype. So I write small Python programs that read the mess, clean it up and hand back structured data — like the DIU Routine Scrapper below, which turns Daffodil International University's multi-sheet class routines into clean JSON with pandas and openpyxl. No servers, no dashboards, just a script that runs in a second.

  • 5Apps & tools shipped
  • 2Browser extensions published
  • 0Telemetry, ever
routine.xlsx → routine.json

Python automation

Scripts that do the repetitive work so nobody has to. Written to be read, re-run and handed over.

  • Excel, CSV and messy real-world data parsing
  • Batch jobs, scheduled runs and CLI tools
  • JSON, report and document generation
  • Scraping and API glue where there is no API
  • Python
  • pandas
  • openpyxl

Data & spreadsheets

Turn a workbook into something a program can actually use — without losing a single row on the way.

  • Multi-sheet workbooks read in one pass
  • Metadata, headers and tags extracted cleanly
  • Values split into structured keys
  • Search, filter and export exactly what you need
  • Excel / Sheets
  • CSV
  • JSON

Always-on scripts

The best automation is the one you stop thinking about. Small jobs that just keep running.

  • Planned as a small, single-purpose tool first
  • Clear logs and safe re-runs by default
  • Run locally, on a schedule, or from CI
  • Documented so you can run it without me
  • Automation
  • CI/CD
  • CLI

How I build

Three rules every project gets checked against before it ships.

See the code on GitHub
Principle 01

Everything ships local-only. Your data stays on your device — offline-first storage, no analytics and no silent network calls.

Private by defaultOffline-first · zero telemetry
Principle 02

Every megabyte has to earn its place. Apps stay lightweight, quick to open and kind to low-end phones and slow connections.

Small on purposeLight builds · fast starts
Principle 03

Plain, readable code and honest interfaces. If something is complicated, that is my problem to solve — not yours to notice.

Clarity over clevernessReadable code · honest UI

Things I've built & run

Real projects, built and shipped — Flutter and Android apps, a retail management platform, browser extensions and the Python tools that keep campus life organised. Click any project for the full story.

05 — Process

How we'll work together

Simple and transparent — you always know what is shipping next and what I need from you.

STEP 01

Discover

We talk through the idea, who it is for and what has to work on day one — and I tell you honestly what I would skip.

STEP 02

Plan & design

Screens, data flow and scope get pinned down before any code — so the look, the stack and the timeline are agreed.

STEP 03

Build

Small milestones, shared early. You get working test builds, a live preview URL or a runnable script as it grows.

STEP 04

Ship & support

Signed APKs, deployment, a clean handover with docs — and I stay around for fixes and updates afterwards.

06 — Contact

Have a project in mind? Let's build it.

Tell me what you need — a Flutter app, an Android app, a website, a browser extension or a script that kills a repetitive task. I read every message and reply personally.
