About

I am a software developer with over 12 years of experience, working mostly as Java/Scala back-end, distributed systems engineer.

I graduated from Imperial College London in 2012 with First Class honours in Computing. During my studies I acquired an in-depth understanding of Object-Oriented programming, Data Structures, Algorithms and Software Design. For the past 12 years I have worked in the Investment Banking industry atMorgan Stanley as a back-end Java developer developing distributed, highly-scalable systems. I possess an in-depth knowledge of Java programming language and my expertise includes:

Software systems and architecture design
SiteReliability Engineering - building scalable, highly available systems
Multi-threading/concurrency
Performance optimisation
Cloud migration/deployments

I have also been recently involved in training of AI models. As part of that role I am responsible for evaluating AI-generated responses to coding/reasoning questions, as well as generating and rating coding conversations with chat-bots in a classroom teaching style.
