Hi, I'm Julian. 

Developed user and checkout-related micro-services in Go, and configured them for use in event-driven backend architecture via Solace Pub/Sub Event Broker.

Refactored, extended monolith code (.NET Core/C#) into microservice architecture with Go/C# hybrid.

Developed booking and promo-code related job servers for use in processing 1000s of jobs per day.

Implemented Stored Procedures in MySQL to optimise heavy DB writes (1M rows) from 25mins to 30s.

Wrote extensive unit tests for new features implemented, utilising mock service & dependency calls.

Utilised tools/frameworks such as AWS, Redis, Elasticsearch, ORMs, & APIs like Checkout.com.

Used GitHub Actions as a CI/CD pipeline to deploy services on AWS ECS.

Built mini-library management tool with ReactJS front-end & Express/Node backend for beneficiaries.

Conceptualised and developed a Bluetooth Low Energy IoT control device to facilitate two-way communication between IoT devices. Involved in ideating both software and hardware design features.

Developed all embedded software features with C++, and primarily used open-source BLE libraries to achieve end-to-end connectivity with all existing products.

Utilised I2C protocol to facilitate communication between MCU and downstream hardware actuators.

Performed calculations and software optimization to ensure maximum battery endurance.

Led and architected the design, testing, and deployment of client/server devices using BLE protocols.

Avetics is a drone solutions company that offers end-to-end services, builds custom drones and software.

Developed a dashboard for drone asset management, with ReactJS front-end & Express/Node backend.

Utilised C++ to implement critical mechatronic functions on tethered-drone systems, including an automated landing platform, and integrated sensor modules such as load transducers.

Programmed and implemented other integrated components including the DRV8825 Stepper Motor Drivers, L298N dual H-bridge controller/driver, & various other Stepper Motors and Linear Actuators.

Developed related embedded systems to facilitate communication between multiple microprocessors (ATmega2560) and an Android App.

Conceptualised, designed, & manufactured (via Fused Deposition Modelling) a new cathode oxygen duct for experimental hydrogen fuel cells, there by achieving a 7% reduction in fuel cell flooding. Primarily used Solidworks as main CAD software.

Optimised individual cell performance by running advanced simulations (via Solidworks Flow Simulation) on different variations of cell design.

Utilised additive manufacturing technology to design jigs to optimise fuel cell assembly processes. (Using a variety of materials such as PLA, heat treated PLA, TPU, etc)

Operated, maintained, and troubleshooted 3D Printers, including helping to optimise prototype strengths and production times.

Determined areas of improvement for fuel cell manufacturing processes by actively taking part in various steps of the production line and helping to optimise for performance and reliability.

Managed Climb Asia's e-commerce website, and Instagram page. Created numerous social media collateral for various product campaigns such as Product of the month, as well as more informational campaigns such as 'Choosing the right equipment'.

Led a social media campaign to improve follower count and increase engagement. Culminated in a product giveaway.

Designed various product labels and signs for use in Climb Asia's physical store.
