Keyvan Mozaffari

Jan 2024 – Present

I lead mobile development for a real-time, cross-platform competitive gaming application. I engineered WebSocket mechanics for real-time user matching and low-latency gameplay synchronization, and refactored caching and state management with Redux Toolkit to eliminate UI memory leaks and improve frame-rate responsiveness. I also mentor engineers through code reviews and establish coding standards across mobile and PHP/Laravel backend layers.

Jan 2025 – Jan 2026

I architected and deployed mobile solutions across fintech and tourism, including a secure clinic payment solution using Stripe Terminal SDK, NFC, Bluetooth, Apple Pay, and Google Pay that achieved a 99.9% transaction success rate. I developed real-time state synchronization for a tourism application, reduced app load times by 30% on legacy devices, and built Fastlane and CI/CD pipelines that cut deployment time by 40%. I also established code review practices that improved team velocity by 25% and reduced post-release bugs by 40%.

Jan 2021 – Jan 2024

I built, maintained, and deployed multiple high-scale white-label mobile applications from a unified React Native codebase. I migrated state management from Redux to React Query, reducing unnecessary API overhead by approximately 20% and improving offline stability. I also engineered real-time communication, chat, and push notification modules with Socket.io and Node.js, and created Fastlane CI/CD pipelines that eliminated manual App Store and Google Play deployments.

Jan 2020 – Jan 2021

I delivered responsive omnichannel customer support interfaces across web with React.js and mobile with React Native. I contributed to a shared UI design system by engineering reusable component architectures that reduced development time for new modules. Through cross-browser testing and automated unit tests, I reduced customer-reported UI bugs by 35%.

Jan 2018 – Jan 2020

I developed mobile products for multiple clients, including a peer-to-peer payment application with a React Native frontend and secure PHP backend, a quiz game scaled to more than 10,000 active users, and a multi-vendor marketplace and trading platform. I worked across React Native, PHP, CodeIgniter, and MySQL to deliver full-stack mobile solutions.

Jan 2017 – Jan 2018

I led the core feature development team for an online insurance platform, defining technical specifications, designing complex database algorithms, and driving object-oriented architecture improvements. I managed agile operations including pull request approvals, performance reviews, task estimation, and technical mentoring for a growing engineering team.

Jan 2014 – Jan 2017

I worked as a senior full-stack developer and team lead, contributing to software development and guiding engineering delivery. I applied full-stack development practices and team leadership across project implementation.

Jan 2013 – Jan 2014

I worked as a senior full-stack developer, contributing to the development and maintenance of software applications across frontend and backend layers.

Jan 2010 – Jan 2013

I worked as a senior backend developer, building and maintaining server-side application functionality and supporting backend software development.
