Developing DeepPCB a Distributed Reinforcement Learning (RL) library. Making programmes run faster.

London, England, United Kingdom

• Developed a Distributed Reinforcement Learning (RL) library as a member of the Research team working with the Product teams, using JAX, TensorFlow, Ray and DeepMind libraries. Accomplishments using Python and C++:
• Promoted as a result of achieving for all future experiments, 95% CPU and 39% GPU cost savingswhilst reducing training time by 61%, for one of the applied revenue-making products. Primarily attained by implementing a.
• Increased throughput by 321% and reduced all experiment costs by 60% by implementing a C++ gRPC server hosting GPU TensorFlow functions called by CPU only machines.
• Developed a multi-phase pipeline, starting with Behavioural Cloning, followed by Transfer Learning into Curriculum training, in partnership with one of the product teams.
• Wrote a Transformer in JAX and successfully trained it for one of the product teams.
• Used SEED-RL, a centralised inference server, for scaling the training of billion parameter models.

Oxford, England, United Kingdom

• Improved real-time monitoring and data aggregation of IoT devices used for controlling thousands of domestic batteries hosted across the UK and Australia for electricity grid stabilisation services. Accomplishments.
• Sped up by 10x the data aggregation of near real-time device per-second statistics.
• Achieved a 15x faster run-time for calculating daily statistics about their IoT devices.
• Analysed data and developed methods to automatically classify their customer IoT devices with fault codes and automatically notify the customer support team. I increased the range of faults that we could detect by 80%.
