Cover image for From ACH to Card Payments:
From ACH to Card Payments: Building Scalable Payment Systems for US Businesses Over the past few years, I’ve worked closely with US-based businesses to design and implement secure, scalable payment systems across ACH, online card payments, and card-present (terminal) environments. My experience spans platforms like North.com (http://North.com), NMI, and other payment APIs—supporting everything from recurring ACH billing to fully integrated in-person payment solutions using physical terminals. On the ACH side, I’ve handled bank account verification, transaction lifecycles, and returns such as NSF and failed debits. ACH systems require careful management of delayed settlements, webhook events, and reconciliation—especially within US financial workflows. For online card payments, I’ve implemented secure gateways, tokenization, and optimized checkout experiences to ensure fast, seamless, and PCI-compliant transactions. I’ve also built and deployed card-present solutions, including: – EMV terminal integrations – Tap, dip, and swipe transaction flows – Device configuration and deployment – Real-time syncing with backend systems – Handling reversals, refunds, and partial approvals A critical part of every integration is compliance and security. My work ensures: – PCI DSS compliance for card data protection – Tokenization (no sensitive data storage) – Secure API authentication and encryption – Reliable webhook handling and audit-ready transaction logs From a technical perspective, I specialize in building robust API integrations, webhook listeners, retry mechanisms, and fail-safe systems that continue to operate reliably under real-world conditions. Key solutions I’ve delivered: – ACH debit and recurring billing systems – Online card payment integrations with secure token flows – Card-present terminal integrations – Real-time transaction systems using webhooks – Payment failure handling and reconciliation logic – CRM and internal dashboard integrations Working in the US payments ecosystem has given me deep exposure to compliance requirements, operational challenges, and the importance of building systems that are both secure and scalable. My focus is simple: build payment systems that are reliable, compliant, and seamless—whether online or in-person. Open to collaborations in fintech, payments, and API integrations.

Cover image for CandleMe — Interactive Digital Participation
CandleMe — Interactive Digital Participation & Engagement Platform CandleMe is a large-scale interactive digital platform designed to connect physical experiences, digital participation, organizations, communities, and persistent user journeys through a unified web experience. I contributed to the product as a full-stack engineer, working across an established production codebase and handling functionality that extended far beyond traditional web application development. My work included complex frontend interactions, application-state integration, backend-connected user flows, organization configuration, QR/direct-link experiences, and performance-sensitive real-time graphics using Three.js and PixiJS. One of the defining parts of CandleMe is its interactive candle experience. Rather than functioning as a conventional website, the platform combines application logic with rich visual rendering to create dynamic experiences that respond to real product state and user interaction. The candle and flame systems were built as functional parts of the application—not simply decorative animations. They had to integrate correctly with surrounding UI, application state, configuration, navigation, and the broader product journey while maintaining smooth performance across different browsers and devices. Core Product & Engineering Areas Interactive Candle Experience The product includes highly interactive visual experiences powered by Three.js and PixiJS, with custom flame effects and graphical behavior integrated directly into real application workflows. This required balancing visual quality with browser performance, device compatibility, responsive behavior, and application-state synchronization. Production Graphics & Performance Optimization Real-time graphics introduce a completely different set of engineering challenges compared with standard frontend development. I worked on optimizing the rendering experience across devices, including testing flame effects at approximately 45–60 FPS on a Galaxy A24 and a stable 60 FPS on an iPhone 15, while also validating compatibility with Apple/Metal-based rendering environments. This involved careful attention to rendering behavior, visual consistency, performance, and differences between local and deployed environments. QR & Direct-Link Entry CandleMe supports experiences that can begin through a QR scan or direct link, creating a bridge between physical locations and the digital application. Users can enter the relevant CandleMe experience without navigating through a traditional application onboarding flow, making the system suitable for physical venues, activations, events, and distributed experiences. Persistent Candle Experiences A candle can represent more than a single interaction. The product is structured around persistent digital experiences that users can revisit, interact with, and share. This required product flows that maintain the relationship between the candle, its configuration, its destination, and the environment in which it is being used. Configurable Destinations & “Doors” The platform supports configurable destinations or Doors, allowing CandleMe experiences to direct users into different journeys depending on the organization, location, campaign, or use case. This adds an important configuration layer to the product because different deployments can use the same underlying platform while presenting different experiences to users. Organization Ownership & Management CandleMe includes organization-level functionality that allows experiences to be created and controlled within a larger operational structure. The system needed to support ownership, organization configuration, locations, plans, activations, and the relationships between these entities rather than treating every candle as an isolated object. Locations & Physical Environments The product is designed to operate across real-world environments. Candle experiences can be associated with physical locations and organizational contexts, allowing the digital platform to extend into venues, events, communities, hospitality environments, campuses, wellness spaces, and other physical settings. Activations Organizations can configure and manage activations around specific CandleMe experiences. This introduces another layer of application state and business logic involving where an experience is deployed, how users enter it, what configuration is active, and which organization owns or manages it. Responsive Cross-Device Experience The product needed to work effectively across desktop and mobile environments because many users enter the experience directly from their phones after scanning a QR code. The visual rendering layer, UI components, and application interactions therefore had to remain responsive and usable across very different viewport sizes and hardware capabilities. Integration With an Existing Production Application A major part of the engineering challenge was working within a large existing PHP-based frontend/backend application rather than building an isolated prototype. New interactive functionality needed to integrate with existing business logic, state management, navigation, backend-driven configuration, and production user flows without disrupting established behavior. That required understanding the existing architecture first and then introducing new functionality in a way that remained maintainable and compatible with the rest of the system. Technical Complexity CandleMe demonstrates a combination of several engineering disciplines: Full-stack product engineering for the wider web application and business workflows. Creative frontend engineering for highly customized interactive experiences. Three.js / WebGL-style rendering for browser-based visual effects. PixiJS integration for performant interactive graphics. Backend integration with a mature PHP application. Performance engineering across mobile and desktop hardware. Responsive application development for QR-first mobile user journeys. Configuration-driven architecture supporting organizations, locations, activations, destinations, and reusable experiences. The project required thinking beyond individual pages or API endpoints. Features had to work together as part of a larger production ecosystem where the visual experience, backend configuration, organization structure, and user journey were tightly connected. Result The result is a production platform that combines interactive web graphics, physical-to-digital experiences, organization management, configurable user journeys, responsive UX, and full-stack application engineering within a single product. For me, CandleMe represents the type of engineering work where frontend, backend, architecture, performance, and product thinking overlap—requiring both the ability to build technically complex functionality and the judgment to integrate it safely into an existing production system.

Cover image for YouTube Captions Management System A custom
YouTube Captions Management System A custom web-based system was created for managing YouTube videos, captions, and auto-play with a timer. The project began from scratch with a single HTML text file containing a basic timer and was expanded over time through 100+ development phases into a complete, scalable platform. Built with PHP/MySQL and AJAX/jQuery, the system supports multiple user logins for managing operations seamlessly. Additional modules included a custom quiz system, live timer, and advanced features, all structured with clear, well-commented code. This made it simple for the client to maintain and update with only basic knowledge of HTML, CSS, and JavaScript.

Cover image for Video Recorder 480p I created a
Video Recorder 480p I created a simple mobile app for recording on wide angle with low possible size of file so now I can record even 10 minute video for about 190 MB only while before it was taking at least 500 + MB or even GB for more file length. Built-in camera recorder does not allow 480p and standard quality and they forced to record on 720p and 1080p. I don't need that because most of my recording is done with front camera and back camera and that's all I needed. So finally my own simple mobile app to solve a real world challenge and now I don't need to rely on ads and get distracted. If you need help developing your mobile app, contact me.

Cover image for I tried a lot, but
I tried a lot, but I couldn't find any writing tool that would allow me to write easily and quickly, not even a single mobile app. I don't know why people are so obsessed with creating complex apps. The real problem remains that why doesn't any developer understand the importance of solving someone's problem? Now I had to create a simple, instant, anytime writing app and now my problem is solved. I can write in Urdu and English at any time and it is also saved in a folder and I can easily copy to the computer. That means it's easy for me to back up, otherwise when I was installing many android apps, they won't allow me copy data easily. I've solved my problem. No more ads, no more data stealing, simple and safe! If anyone need help for developing simple apps, just contact me. Note: I don't work with database on mobile apps as of now. However I work with database on web applications (php/mysl)
