Two open-source builds you can read line by line, and four pieces of production work delivered at Technyx. Each case study explains the problem, the decisions and the result.
Public repositories with tests and architecture docs.
A versioned REST API for digital wallets where every credit, debit, transfer and reversal produces balanced ledger entries and a full audit trail. Built to show how money-handling code should behave when requests are retried, concurrent or malicious.
A complete e-commerce platform for the Pakistan market that can extend to other markets without a rewrite: storefront, customer accounts and a full admin area, with the checkout and inventory logic built to stay correct when real people use it.
Client and employer code is private, so these case studies describe the problem and approach without exposing anything confidential.
A production backend serving meal-subscription operations: user profiles, multi-tier subscription plans, custom meal schedules, digital wallets, order histories and automated kitchen and delivery dispatch lists.
A large-scale restructuring and modernization of an enterprise WordPress site with 800+ pages of multilingual, dynamic content, moving hardcoded blocks into custom post types, ACF field groups and clean templates.
Theme-level development for a high-traffic production Shopify store: custom Liquid templates and sections, a bundle selector, and a lightweight cart drawer built on Shopify's AJAX Cart API.
Secure integration of third-party payment gateways and verification modules into custom PHP and Laravel applications and e-commerce platforms, built so a payment is never lost, double-counted or trusted without verification.
