Full-Stack App & Web Developer | AI & Store Launch , UI/UX
I designed and developed a modern AI-powered travel planner mobile app using Flutter for both iOS and Android. The app allows users to create personalized travel plans, explore destinations, discover verified local tour guides, manage upcoming and previous trips, and organize their complete journey from one platform.
The application also includes smart budget planning, daily expense tracking, category-based spending breakdowns, user profiles, guide listings, and responsive screens. I focused on delivering clean UI/UX design, smooth navigation, scalable functionality, and a consistent experience across Android and iOS devices.

A modern Digital Fuel Pass App designed to streamline fuel distribution through QR-based verification, real-time tracking, and simplified workflows.
The goal was not just to build another app —
but to create a system that reduces friction, improves control, and works in real-world scenarios.
🎯 Problem
Traditional fuel distribution systems face major issues:
• Manual verification processes
• Lack of transparency in fuel usage
• No real-time tracking
• Complex and slow user experience
• High chances of misuse or fraud
Users struggle with unclear processes, while operators lack control and visibility.
💡 Solution
We designed a smart, workflow-driven system that simplifies the entire process:
• Digital QR-based fuel pass for instant validation
• Real-time fuel balance tracking
• Automated refill cycle management
• Clean and guided user experience
• Centralized data for better monitoring
The focus was on reducing steps, not adding features.

The client wanted a dependable safety app that users could trust in real, high-stress situations—where every second matters and hesitation isn’t an option.
I built a real-time mobile solution with instant SOS alerts, live location sharing, trusted contact notifications, and a discreet silent mode. The interface was intentionally designed to feel calm, clear, and premium, helping users act quickly without panic.
The result is a secure, scalable, production-ready app that prioritizes speed, reliability, and user confidence in critical moments.

Ever struggled with testing payment QR codes?
If you work in banking or fintech, you probably know how challenging QR payment testing can be. You generate an EMVCo QR code, but then you need to validate its structure, check the CRC, test invalid QR data, or encode and decode Consumer QR codes.
Sometimes, even a small error in the QR data can cause a payment to fail. Finding that error can take a lot of time. We noticed that these tasks often require different tools. So we thought, why not build one app that can handle them all?
That's how AttoQR came to life.
At AttoExa Solutions, we built AttoQR to help banking professionals, fintech developers, and QA testers work with QR codes more easily.
Here's what you can do with AttoQR:
✅ Generate and Scan QR Codes
✅ Generate EMVCo Merchant & Consumer QR Codes
✅ Validate and Verify QR Data
✅ Generate and Test CRC Values
✅ Create Valid & Invalid QR Codes for UAT
✅ Generate Encryption Keys for Consumer QR Encoding & Decoding
No need to switch between different tools for these tasks. You can do it all from your phone.
We're happy to share that AttoQR (Beta) is now live on Google Play.
This is our first release, and we're looking forward to making it better with feedback from people who actually work with payment systems. If you're working in banking, fintech, digital payments, or software testing, give AttoQR a try.
We'd love to hear what you think and what features you'd like us to add next.
📲 Search "AttoQR" on Google Play to download the app.

New to Contra
Full-Stack Next.js / Node.js Developer | Framer
Title: Restaurant Management Platform: Full Stack Development for Olik Lab
Company: Olik Lab
My role: Full Stack Developer
Product: Olik Eats, a complete restaurant management system
Running a restaurant means keeping track of phone orders, online orders, the kitchen, your staff and your stock all at once. When those live in separate tools, orders get missed, the kitchen gets confused and the owner is left guessing. I helped build Olik Eats to solve that, working on both the customer-facing side and the back end.
What it does for a restaurant owner
Get more orders: your own branded online store for delivery, pickup and dine-in, so you aren't giving a cut to third-party apps for every order.
Keep customers informed: customers follow their order live, from confirmed to cooking to on the way, so fewer "where is my food?" calls tie up your staff.
Run a smooth kitchen: counter and online orders appear instantly on a kitchen display, and receipts print automatically. Nothing gets lost on paper.
Update your menu in seconds: change prices, mark items sold out, add sizes, add-ons and specials without calling a developer.
Manage your team: staff roles, permissions and shift attendance in one place.
Bring customers back: promo codes and a loyalty points program that rewards repeat orders.
Take bookings: table reservations alongside your orders.
Keep stock under control: inventory is deducted automatically as orders are prepared, so you know when you're running low.
Get paid safely: secure card payments, with prices verified on the server so they can't be tampered with.
See how the business is doing: a dashboard showing sales, busiest hours, top-selling items and order trends.
