    Use Cases

    When people think of product development, they often imagine a single app. But in one of my most complex and rewarding projects, we weren’t building just one — we were building an entire ecosystem of applications designed to work together as a single, seamless EdTech platform.

  • From Engineer to Leader: My Journey

    Solutions, Use Cases

    As the tech lead on this project, I oversaw the transformation of our legacy monolithic application—handling everything from user accounts and digital card sharing to lead capture and CRM integration—into a suite of independent microservices running on Google Cloud Platform. In this article, I’ll share both the theoretical underpinnings and the hands-on steps we took…

    Solutions, Use Cases

    While this Loan App system dates back to 2018—built on Laravel 5.x and a React 16 (without Hooks) front-end, it had a structured, layered test suite. In 2018, the popular choices included ESLint and JSCS for linting, PHPUnit for PHP, Jest + Enzyme for React, and Cypress or Selenium for end-to-end. Below, we’ll map out five…

  • Securing JWTs with HTTP-Only Cookies in E-Commerce Platform

    April 7, 2022
    Solutions, Use Cases

    Imagine your E-Commerce platform uses a Next.js/WordPress monolith that seamlessly routes users to two React SPAs (seller and customer) via JWTs and OAuth 2.0. To harden this flow against XSS and CSRF, we have to shift all tokens into HTTP-only cookies, implement rotating refresh tokens, and provide a robust logout/expiry strategy. By the end, you’ll…
