IT, AI & Coding Skills

What I've learned by building

What I can do

Building and testing my own apps taught me how software, databases and websites work from the inside, and how to use AI tools to get things done faster.

Working with large data files: cleaning, sorting and finding patterns
Pulling figures out of PDFs and Word files quickly, then cross-checking them
Understanding how software, databases and logins actually work
Keeping systems safe with good passwords, backups and privacy
Making simple web tools and trackers to save repetitive work
Using AI assistants for writing, summarising and coding

✨

AI & New Technology

I keep up with AI tools and use them every day to write, test and review code faster. I also use AI to summarise long documents, draft content and find patterns in data, and I always check what it produces.

Practised in: AI-assisted development of all my projects, opt-in AI parsing in Sense

🔐

Security & Access Control

Access control and passwords/PINs, keeping secret keys out of code, regular backups and recovery, and version control so every change is recorded.

Practised in: Mission BPSC PIN-protected sync, key backups, Git history

📊

Data Analysis

Cleaning, sorting and classifying records automatically, with rules that flag unusual entries for a closer look.

Practised in: Sense transaction parser (classify → rules → review)

📄

Document Processing

Turning Word and PDF documents into structured, searchable data with Python. Extraction is done twice and checked by hand before anything is relied on.

Practised in: Chemistry Notes, PYQ extraction for Mission BPSC

🛡️

Web Security

Checking a web application for common weaknesses: exposed keys, missing security headers, unsafe input handling and over-broad permissions. Each finding is fixed and then re-tested.

Practised in: repeated security reviews of my own apps

🧾

Data Privacy

Masking personal details such as account numbers on the device, consent banners, privacy policies and a working data-deletion process. I know what good personal-data handling looks like.

Practised in: Sense on-device masking, consent & deletion flow

☁️

Cloud, Automation & Testing

Cloud hosting and online databases, scheduled jobs and bots, and automated browser tests that confirm a system really does what it claims.

Practised in: Cloudflare, Telegram reminder bot, Playwright tests

Projects

Where these skills were put into practice

Pagewood study timer running in the browser

App development · Flutter

Pagewood: Focus Timer

A calm study timer I made because I kept getting distracted by my phone while studying. A small tree grows on screen for every minute you stay focused.

Pomodoro-style timer with a hand-drawn growing-tree animation
Built once in Flutter, runs on Android and in the browser
Works offline, with no sign-up and no ads

Web app · Data & AI

Sense: Expense Tracker

A personal expense tracker I built to manage my own monthly spending. It sorts expenses into categories and shows where the money goes.

Automatic classification of transactions using rules, with optional AI help
Personal details masked on the device, and data stays offline
Try it without an account using sample data

Other experiments

Prototype · iPhone

Photo Cleanup

A small iPhone app prototype for sorting a cluttered photo gallery by swiping to keep or delete. I built it to learn SwiftUI. It isn't published.

Automation

Study reminder bot

A Telegram bot that sends my revision list twice a day. I mark each question Easy, Good or Hard, and it decides when to show it again.

💡

Why I do this

I enjoy solving small everyday problems with technology. These projects taught me how to organise information clearly, automate routine work, and make things simple for the person using them. I'm happy to help with similar small tools or digital work in the office whenever needed.
