About Me

Armando Jiménez

Senior Software Engineer

Building secure, scalable systems across banking and fintech with 9+ years of experience.

Expertise

I deliver end-to-end solutions across mobile, frontend, and backend systems, including cross-platform mobile development, scalable server-side services, and polished user interfaces. I'm known for taking full ownership of projects from technical analysis and design through implementation, testing, and production release.

Current Impact

I've driven major engineering initiatives across mobile development, backend services, IAM, and payment workflow architecture. I've owned the automation and optimization of core financial processes, designed end-to-end SFTP and payment workflows, built REST services, improved monitoring and reliability, and helped define engineering standards and documentation across the team.

Published Apps

Outside of my full-time role, I've designed, built, and published a suite of mobile applications focused on self-growth and positive mindset. These apps have reached over 400K downloads and maintain consistently high ratings across iOS and Android.

What Drives Me

I'm driven by clarity and ownership and a passion for building software that performs reliably under real-world demand. I'm continually growing as a technical leader, mentoring others, and taking on complex challenges that require both depth and cross-functional collaboration.

Verses, affirmations, customisation and even more. You can even create your own verses here. Like YouTube shorts, but with Bible verses and affirmations. I really recommend this app. It's good, especially with the Bible (like using this app before or after reading the Bible).
