Orchestrated and implemented the Python 2 to 3 migration of our CMS including not only the necessary language changes and idiomatic improvements, but the infrastructural changes (required to support a very different App Engine version) and therefore the needed architectural redesign as well.

Designed and built an asynchronous task executor framework to declaratively define / compose and run jobs on GCP with built-in reporting system, monitoring UI, and time-box management (intended to be a drop-in replacement for the old App Engine SDK's Pipeline).

Designed and implemented a serverless health monitoring system.

Implemented an almost complete CD / CI workflow system on top of GitHub Actions.

Designed and implemented a low-level, arbitrary length and alignment bit-parsing and slicing mechanism in Python and C on top of Redis' bitfields to reduce internal network traffic and size of the in-memory caching layer.

Designed and implemented a high-level proxy objects hierarchy on top of Stripe's API in Python to support the latest SCA requirements as a backward compatible, robust, idiomatic, and flexible wrapper.

Designed and implemented a modular, composable, declarative, and reactive animation framework in TypeScript to support CSS, JavaScript, and Lotti-animations to unify all animation types and support highly complex dynamic compositions.

Redesigned and implemented an internal (customer facing) message editor with integrated support for a large number of key features provided by the company in Python and JavaScript.

Designed and implemented an efficient (both size and speed wise) rich-text protocol and rendering engine in Python and JavaScript to support custom text field editing and serialisation.

Implemented native Python 3 support in AWS Lambda in C when Amazon only supported Python 2 to develop services targeting this version.

Designed and implemented a modular, extensible, parameterised, and 3D printable construction toy system in OpenSCAD and an accompanying framework in Python and Arduino/C++ to make building, programming, and, experimenting with robotics accessible to anyone.

Designed and implemented an event-driven, high-level, and declarative hackathon-framework and runtime in C with Python and JavaScript bindings to help teach and recruit teams to the talent-programme of the company.

Designed and implemented a hand-gesture-driven 3D modelling VR simulation in C and Python targeting the Oculus Rift and the Leap Motion, on top of Blender's game engine to represent the company on an exhibition.
