🏦 Senior Software Engineer @ ANZ (SEISMA) 🇦🇺

🌮 Senior Software Engineer @ Zambrero 🇦🇺

As a burrito and Mexican food lover for many years (and very conscious of what I eat), the idea of working for a company that sells healthy and delicious food while helping others (like donating meals to end hunger with Plate4Plate and Plate4Plate Day, where everybody gets involved and helps pack meals!) aligned perfectly with my personal values and professional drive! 🏎
And then, of course, building the best software applications is deeply part of my DNA! 💥

I worked at Sam Prince Group, Zambrero’s head office in Sydney, as the principal senior software engineer with a team of two, reporting directly to the CIO, and focused on the food delivery apps, adding value to every Australian Zambrero store for online orders! 🇦🇺

Some of the things I worked on as the principal software engineer of the company:
→ Integrated from scratch a delivery partner API service (DoorDash Drive) as a white-label delivery solution into the company’s native apps, website, and the restaurant’s back-office portal software. As the lead engineer, I coordinated the project’s vision and roadmap, managed tasks through a Kanban Jira board with another developer, and held weekly catch-ups with the DoorDash account managers to ensure a successful integration of DoorDash into their delivery network.

→ Improved the security of the app and implemented measures to prevent transaction fraud 💸

→ Optimised scalability and site reliability: when I started, the company’s online ordering services were going down nearly once a day. I implemented several iterations to improve scalability, including optimising AWS infrastructure, EC2 task policies, backend caching, expensive SQL queries, data mapping, custom Pronto 4GL API changes, and database indexes, reducing downtime from ≈8 times per week to zero 🚀

→ Maintained both the Electron back-office software and the Nucleus custom update server.

→ Worked with Pronto (ERP software), through Pronto Xi and Connect, and their 4GL SPL programming language.

→ Managed infrastructure and deployments through AWS services.

→ Used Docker to improve reliability and scalability with AWS ECS, Fargate, and Postgres RDS, while using Route 53 for routing and monitoring critical health checks.

→ Integrated CD deployment pipelines from Bitbucket to AWS ECS.

→ Implemented CI containerised testing pipelines.

→ Improved security and implemented critical fraud detection based on unusual user behaviours and specific patterns, and added SMS account verification across all platforms using a micro-comm server.

→ Developed and maintained custom PHP Craft CMS plugins used for the public Zambrero.com.au website and its specific regions.

→ Handled Online-To-Offline (O2O) complexity of the app, for orders scheduled while restaurants were closed. Investigated inventory stock support for items when some items were sold out or unavailable at specific stores.

→ Defined app deployment strategy with Fastlane 🚀

→ Conducted technical interviews and testing processes for engineers joining the team.

→ Wrote most of the software development documentation and key processes on Confluence to help the team and non-developers understand and troubleshoot more easily, and created onboarding pages to help new developers set up their environment faster, reducing onboarding time by approximately 75%.

→ Migrated the platform’s SSO from Google to Microsoft authentication for the restaurant Electron back-office software and manager tool.

→ Applied best coding practices, IoC principles, and design patterns to design endpoints and implement domain logic.

→ During my time at Zambrero, successfully released 22 iOS versions and 19 Android versions to the App/Play Stores, and maintained the listings details.

🛡 Full Stack Engineer II @ Sine.co (Honeywell Forge) 🇦🇺

Worked on both the frontend and backend APIs, as well as microservices and cross-shared packages of the core visitor management cloud-based product, using JS ES6/7, React, Node 14–16, Express, TypeScript 4, Sequelize/Postgres, test automation with Cypress for integration and end-to-end tests, event-messaging systems (SNS/SQS), New Relic, Docker, Jenkins, and several AWS services (EC2, ECS, Fargate, S3, …). Used pganalyze for benchmarking and measuring the performance of critical database migration changes before production releases.

Was part of the QA automation guild and served as the subject-matter expert, responsible for teaching, documenting, and sharing knowledge within the team, and guiding engineers on the automation setup with Cypress and the in-house Python testing framework. Created screencast videos to help the team at Honeywell get started with Cypress and follow the company’s QA testing specification for writing automated end-to-end tests.

🚀 Principal Maintainer @ pH7Builder Community Builder™

As the creator of pH7Builder (previously known as pH7CMS) and its entire kernel, the pH7Framework, I am still very much involved working on my open-source "Social Community Builder" project during my spare time 😊

● One of the biggest open source projects I have ever coded 👨‍💻 And probably the one I'm particularly most proud of ☺️
● https://github.com/pH7Software/pH7-Social-Dating-CMS
● https://github.com/pH7Software
● Assist users with technical support inquiries via GitHub Issues (including emails, etc).
● Lead the project, manage user issues/feedback, implement the new features/modules, and keep the product roadmap up-to-date.
● Writing the documentation for the end-user (e.g., on https://ph7builder.com/doc).
● More recently, pH7Builder has migrated from PHP 5.6 to PHP 8.1 - https://github.com/pH7Software/pH7-Social-Dating-CMS/pull/937

I've pushed a lot of determination and knowledge for the last 12 years to accomplish the mission I've always dreamed of delivering to the open-source's world, which was to release the first large-scale, free and open-source, social dating builder software.

The project has been nominated twice at the iDate Awards, received several open-source winning awards, and was downloaded over 109,000 times.

🍓Product Owner / Developer / Founder 🍍

Lifyzer Healthy Food Solution™ is a social-food mobile app that aims for transparency and opinions between customers. It allows users to share their feedback on food items and rate them.

Thanks to its clever OCR and barcode scanning technologies (using Google Mobile Vision and Firebase), it also instantly gives the health score and useful details about items you regularly eat or purchase.

In order to give the most reliable data available on the different continents, Lifyzer partially uses OpenFoodFacts, Foodrepo.org, and the US FoodData Central (FDC), which are the biggest open-source nutrition databases.

Lifyzer is another side project I’ve really enjoyed creating and working on! 🤗 Building and marketing from scratch a complex and meaningful project that solves an obvious problem everybody is concerned about is highly rewarding! 🚀

Available on iOS (a native app built with Swift):

As well as on Android (natively coded in Java):
https://play.google.com/store/apps/details?id=com.lifyzer

The apps use a simple REST API built on top of PHP 7.3 and using MySQL database.

Finally, I’m currently working on a food search engine, based on Algolia 🚀

⚡️ Lifyzer is 100% transparent with its users. That’s why the project is 100% open source 💪
