Sony Europe
Software Engineer Contractor
Basingstoke, England
Nov 2022 - March 2024
Core technologies
Python, C#, React.js, TensorFlow, OpenCV, JavaScript, TypeScript, Django, Docker, PostgreSQL
Role description and achievements
- I was asked to return to the Software Quality Assurance (SQA) team to lead the scaling, development and deployment of the machine learning system I had designed and developed in my placement year.
- Using Ansible and GitHub Actions, I developed a CI/CD pipeline to containerise and deploy a Python machine learning application to various international Windows servers. Presently, I am working with our AI engineers in Germany to add new functionality to this Python application, such as automated test case creation.
- I designed and continue to develop a full-stack web application that provides analytics on the Python tool’s data. Built with React.js, Django, Next.js, TypeScript and PostgreSQL; a platform for Sony’s non-technical personnel to make better, data-driven decisions with Sony TV software packages.
- Designed a symmetric encryption protocol for securely transferring user information between internal applications. Recognizing its potential for broader use, I presented it to other teams. Subsequently, I created comprehensive technical documentation and supported various teams in its implementation.
Sony Europe
Software Engineer Contractor
Basingstoke, England
July 2021 - July 2022
Core technologies
Python, C++, React.js, TensorFlow, OpenCV, TypeScript, Django
Role description and achievements
- In the SQA team, I developed a multi-threaded, Python-based machine learning tool coupled with a web application to provide analytics and report generation on the tool’s collected, confidential data.
- I developed convolutional neural networks and a navigation algorithm with object detection to traverse Sony’s TV software. During traversal, the tool would collect mission-critical data on the TV software, which would then be sent to the web application for analysis and visualisation.
- I worked throughout the year with senior Sony engineers and managers to amend and create new test case specifications for the TV software, we then developed our tool to meet these new specifications.
Technology Stack
Core languages
Python
Over two years of commercial experience with Python and used to create my dissertation project.
Java
Was taught Object-Oriented Java at University and built on this with personal mobile application projects.
JavaScript
Strong knowledge of JavaScript from building a web application at Sony Europe and also from building websites for myself and friends/family.
C#
Familiar with C# from developing some of Sony's internal Windows tools.
Swift
Followed a Model View ViewModel (MVVM) architecture when I was developing my mobile application BeautyTruth.
HTML
Confident in HTML from writing my own websites and using .tsx with Sony's web application.
CSS
Learned from the various sites I've built. Used flexbox and CSS modules for Sony's web application.
Frameworks, libraries and supersets
Django and Django Rest Framework
Have been working with Django for just over two years, primarily with my time at Sony.
React.js
Been working with React for over 2 years building enterprise tools. It continues to be my framework of choice for personal projects.
TypeScript
I've always adopted TypeScript for its vast improvement to developer experience. Have over two years experience working with it on enterprise codebases.
PyTorch
My dissertation project is written with PyTorch for it's higher level of flexibility for machine vision applications. You can see this project here.
TensorFlow
Good knowledge of TensorFlow from university. I'm also familiar with TensorFlow Lite, having used it for enterprise IoT devices.
Version Control
Git
Several years I've been working with Git for my projects and enterprise work.
Databases
PostgreSQL
Familiar with designing structured, relational schemas for enterprise tools
MongoDB
The unstructured database of choice for my own projects and at my time at university. Have experience working with this in Sony also.
Containerisation
Docker
Containerized various web applications with docker and have deployed Python containers to various international Windows servers.
Cloud Services
Amazon Web Services
For the Software Engineering module in Year 2, we needed to build a web application in groups. For our project, we used:
Elastic Beanstalk
We used BitBucket Pipelines to containerise our web application and deploy it to our Elastic Beanstalk environment.
Lambda
To make periodic corrections to our MongoDB database.
EC2
Our application was hosted on an EC2 instance which we integrated with our NGINX reverse proxy.
Cognito
To handle our user authentication
Platforms
Windows
Worked on Windows Server 2019 when I was developing with some of Sony's C# internal apps.
Linux
Good unix skills built over time working with containers, WSL and primarily Debian-based distros.
BePanda
Small project selling reusable drink flasks and cups
Oct 2018 - Present
Founded by myself, I wanted to provide people with an alternative to single use plastic coffee cups.
I designed and branded two products and shared profits with a plastic pollution charity.
I've sold them in local garden centers and are available online.
“To accelerate the transition to natural and ethical cosmetic products”
A mobile application to analyse ingredients on beauty products.
April 2021 - July 2021
Started by me and some friends at university, we wanted to increase the convenience and confidence for consumers in identifying natural and ethical cosmetic products.
I developed a barcode scanner in Swift that would fetch from a product database and display product information. I picked a database by a company called Digit-Eyes who after speaking to them, found that they store all their data onsite and have data on millions of barcodes. The data is kept up to date by scraping product webpages for each barcode.
However, I made the decision to pause development on BeautyTruth to focus on my placement at Sony.
