I'm Nasir Hossain — Full-Stack Developer.
A self-taught full-stack developer based in Comilla, Bangladesh, building fast, accessible, and genuinely useful web applications and software products for real people and real businesses.
My journey began in 2018 when I was in Class 6. I came across a freelancer named Nasim online and, for the first time, discovered that it was possible to build websites from home, work with international clients, and earn in US dollars. That idea lit something in me. I had no computer, no mentor, and no programming class — only a mobile phone and a relentless curiosity. I started spending 16–18 hours a day on HTML and CSS, motivated by a single thought: instead of wasting time scrolling YouTube and playing games, I could be building something meaningful for my future. By 2019 I had a solid grip on HTML and CSS and was already assembling my first real layouts.
In 2021, I pushed into JavaScript, built mini-projects and full demo websites, and shared every milestone publicly on Facebook as proof of progress. That same year — studying in Class 10 and having just bought my first computer — I became obsessed with English typing and worked my speed up to a professional level. I also took my first steps into React and began experimenting with React Native for cross-platform apps.
In 2022, I learned WordPress and landed real client projects. But with my SSC exams approaching and post-COVID schooling resuming, I made the difficult decision to pause coding and focus on academics — going on to complete my SSC and HSC from an Arts group Madrasah in Comilla. I am currently pursuing a BBA in Accounting at Cumilla Victoria Govt. College. There was no CS degree, no AI tools, no teacher, and no one around me writing code.
In March 2025, I came back stronger. I delivered a professional WordPress project for Gomati Hospital, Cumilla, completed several more client websites, and learned a great deal along the way. But WordPress had a ceiling — limited control, performance bottlenecks, and no path toward the mobile apps and management software I had always envisioned. With the AI revolution accelerating, I made a decisive pivot to modern full-stack development.
On 1 November 2025, I began a structured deep-dive: core JavaScript fundamentals — arrays, functions, async/await, APIs — followed by React, Next.js, Node.js, PostgreSQL, and Supabase. After 1,000+ hoursof YouTube courses, AI-assisted Q&A, 2 demo web apps, 1 demo mobile app, and 3 production-grade client projects — everything is functional and fully under my control.
I used AI — especially ChatGPT and Claude — not as a shortcut, but as a thinking partner. I never asked for code blindly. I asked why something worked, understood the concept fully, and then applied it myself. Today I use Claude Code daily to move 10× faster without sacrificing understanding. I am actively working with real clients, learning something new with every project, and steadily working toward a mission I will reach very soon — Insha Allah.
When I Started Learning to Code —
Documented Proof from Facebook
Every screenshot below is a real Facebook post I shared publicly in 2021 — when there was no ChatGPT, no AI assistant, no shortcuts. Just a mobile phone, free YouTube tutorials, and hours of raw consistency every single day.

Reached 50 WPM on TypeRacer — Pro level. In one month I went from 27 WPM to 50 WPM. Proof that consistency beats talent.

When I started learning about forms and their design in 2021 — building registration forms entirely on mobile.

Practiced JavaScript by building a simple game on mobile using an HTML editor. No laptop, no shortcuts.

Finally built a calculator using HTML, CSS and JavaScript — designed and coded on a mobile phone.

My personal demo site with a typing animation — built on mobile with JavaScript. Made on mobile, designed by Nasir Sarker.

First complete website for a real person. ~800 lines of code. Built on a mobile phone. The moment everything clicked.

2nd target done — a full website for Rachia Madrasah, built using a hand mobile HTML editor.

One more step forward — React JS. Built a custom card layout at localhost:3000. React clicked that day.

Cloned Facebook and Instagram login pages on mobile. Mini practice project to master UI patterns.

Built a Single Page Application behaving like React — using only HTML, CSS and Vanilla JavaScript on mobile.

Started learning React Native on Snack.expo.dev — one JavaScript language for Android, iOS and Web.

Bought "Hatkolome JavaScript" by Junayed Ahmed — my first ever programming book. Curiosity turned into commitment.

GPA 2.50Free Resources That Built My Entire Career
No bootcamp. No paid courses. Just YouTube tutorials, raw Google searches, and in 2025 — AI as a learning companion. Here's every resource that shaped how I code.




The first tool I used for everything. "How to center a div" — search was my teacher before YouTube was even on my radar.
The go-to reference for HTML, CSS and JavaScript syntax. Every beginner lands here first — simple, fast, and always there when you need a quick answer.
The developer's rescue team. Whenever I hit a wall, someone on Stack Overflow had already asked the same question and gotten a brilliant answer.
Since 2023, AI changed everything. I use these as 24/7 tutors — ask anything, get a real answer, go deeper. Not a shortcut, a multiplier.
My first AI learning companion. Explain concepts, debug errors, and explore "why" behind the code — like a 24/7 senior developer.
Great for comparing approaches, understanding documentation, and exploring modern web APIs in depth with real examples.
My favorite for long-form learning sessions, code reviews, and understanding complex architectural decisions step by step.
