04 / How I work
Principle 1
Users first
Every line of code should end up serving someone. I aim for interfaces that are intuitive, accessible and solve a real problem.
Principle 2
Clean and scalable
Code is read far more than it is written. I keep it modular and self-explanatory so the next person can move quickly.
Principle 3
Performance is a feature
I treat speed as a requirement from the start: fast loads and smooth interactions keep people engaged.
05 / About
A bit about me
I'm Tanvirul Islam, a software engineer based in Dhaka, Bangladesh. I design and build web products with clean, scalable code, and I care as much about how an interface feels as how it's built.
I came to engineering from a design degree, which still shapes how I work: I sweat layout, motion and accessibility, then make sure it all loads fast. I love turning ideas into interactive experiences and keeping up with what's next in tech.
Away from the keyboard I'm usually travelling, or, honestly, still coding.

🚀 নিজের একটা project শেষ করলাম — PDF RAG System. RAG (Retrieval-Augmented Generation) নিয়ে অনেকদিন ধরে কাজ করতে চাইছিলাম। এবার একটা production-ready backend API বানালাম — যেটা দিয়ে যেকোনো PDF এ AI-powered question answering করা যায়। কীভাবে কাজ করে? ➡️ PDF upload করুন → text extract হয় → ছোট ছোট chunks এ ভাগ হয় ➡️ gemini-embedding-2 দিয়ে প্রতিটা chunk কে vector এ convert করা হয় ➡️ সেই vectors Pinecone database এ store হয় ➡️ প্রশ্ন করলে top_k relevant chunks (similarity search) খুঁজে এনে gemini-3.1-flash-lite answer generate করে — exact source citation সহ Hallucination কমানোর এটাই key — LLM কে raw knowledge এর উপর নির্ভর না করিয়ে, আপনার নিজের document এর উপর ground করা।

আপনার website-এর LCP কি এখনো 2.5s এর বেশি? 🎯 Honestly বললে — বেশিরভাগ project-এ আমি যেটা দেখেছি, answerটা “হ্যাঁ”। আর interesting ব্যাপার হচ্ছে, এটা শুধু একটা technical metric না — এটা সরাসরি business impact করে 💸 Mobile load speed-এ মাত্র 0.1s improvement অনেক ক্ষেত্রে noticeable conversion uplift দিতে পারে। ছোট মনে হলেও, scale এ এটা huge 📈 গত কিছুদিন ধরে frontend performance নিয়ে deep dive করছিলাম — কিছু practical observation শেয়ার করছি 👇
