About Me

    I thrive on solving problems and personal improvement. During my Master's project, at the University of Oxford, I developed high levels of problem solving and data analysis skills that were necessary to model and visualize complex chemical systems.

    After my degree, I took a role at the consulting startup Tunneys. In this role, I have developed skills in software and programming languages such as: Python, Power BI, Microsoft Fabric and Azure. Working at a startup has required independent and self-accountable learning. This involved implementing production level code & data analysis with little supervision often implementing new techniques and products that were previously not offered by the company, including Python notebooks, web-based reports, Azure Lakehouse & Warehouse storage/analysis.

    In my career, I want to focus on the higher levels of problem solving required when working with Python. I have expanded my skills outside of work by researching python, implementing code in the form of solving tasks/problems and personal projects.

    As a result, my programming and data analysis skills have increased dramatically over the last year and I am continuing to work diligently to further expand these skills.

  • Computer Programming
    Python.
  • As a Data Analyst, I use Python with Pandas & pySpark to process and analyse data. In my spare time I also build projects and solve data structures and algorithm problems.

  • Data Analytics
    Power BI, Power Apps & Excel
  • I present data within Power BI and Excel. Along with building financial models using Excel and Power Apps to allow clients to enter data directly into the model/database within Sharepoint sites & Power BI reports.

  • Data Storage & ETL
    SQL server, data pipelines, Lakehouses & M/Power Query
  • Typically, client data is stored and managed using Data Pipelines & Warehouses/Lakehouses within Microsoft Fabric. Our systems allow for near real-time data processing and forecasting. My implementation of Data Pipelines allows for automatic refresh of analysis, stored SQL procedures & Python notebooks.

  • Data Science & Analysis
    Python, Pandas, Spark & pySpark
  • In addition to using SQL, many of our large-scale data transformations are performed using cloud-based fabric notebooks with Spark & Pandas. My forecasting has been completed using models such as SARIMA to predict the seasonality and adjust the trend of revenue etc.

  • Financial Modelling
    Excel, VBA & Python
  • I have developed financial models including project management for a biotech startup, financial analysis for a large private equity firm and revenue projections for company sales.

  • Cloud Architecture & Web hosting
    Azure Cloud Services
  • One product I developed is a custom web app using Power BI Embedded with Microsoft Entra P1 authentication. This allows clients/businesses to authenticate to their power BI reports without a Power BI license through our custom designed web portal that is hosted on an Azure web app.

  • 2023 - Current
    Data Analyst for Tunneys Consulting.
  • Financial modelling for startup companies.

    I developed several financial models for startup companies, up to revenues of $10 M, that analysed core business metrics such as profitability, revenue growth and customer retention. This was done using Excel and Power BI with data being presented within Power BI reports and in Power BI Embedded reports hosted on Azure Web applications.

    Financial modelling for a large Private Equity firm.

    I designed a financial model to analyse the performance of investments and funds by fund managers to present to shareholders on $100 M investments. As part of this, I cleaned and streamlined their data storage process to allow for extra fund analysis and future scalability. This enhanced the shareholders understanding of their fund finances & forecast profits.

    Project management system for a biotech startup.

    I developed an Excel model with VBA Macros to allocate staff full time equivalence and schedule multiple pharmaceutical projects. As part of this process, I implemented high levels of data validation and automation to improve model scalability and useability.

    Improving company forecasting & analysis techniques.

    Since I joined the company, I have led the new implementation of analysis and forecasting on Microsoft Fabric using Azure Data Factory, Fabric notebooks with Python & Pandas. This has provided SARIMA modelling for our clients to forecast their revenue and profits.

    Improving company data storage & processing methods.

    We have now moved our clients to a cloud storage and computing solution, using Data Warehouses/Lakehouses. This allows for scheduled and automated refresh for near real time data analysis and updating. Combined with Power apps, we enabled clients to directly add data into the SQL Endpoint from their reports.

  • 2023 - Current
    Contracted Tutor for TutorChase.
  • As a contracted tutor for TutorChase, I focus on tutoring Mathematics at A-level and Chemistry up to Undergraduate level. I also mentor students on Oxbridge personal statements and interviews.

  • July 2023
    Chemistry Ambassador for University of Oxford.
  • This was a weekend role as a Chemistry department ambassador. This involved answering questions of potential applicants and giving tours around the Chemistry Research Laboratory.

  • July 2022 - Aug 2022
    Water Technician for Jersey Water.
  • I undertook water testing and analysis including on-site testing, off-site testing & analysis of water testing data.

  • Jan 2021 - Sep 2021
    Medical Laboratory Assistant at OpenCell BioTech.
  • As part of a team, I performed PCR COVID testing for the island of Jersey, scaling up sample testing from 300 to 1,500 samples a day. My role was delegating tasks, managing shifts along with directly testing PCR samples and troubleshooting quality control/contamination issues.

  • Aug 2018 - Sep 2018
    Oxford Interview Tuition.
  • I instructed students on what an Oxford interviewer is looking for and how best to prepare for the interview.

  • Sep 2015 - May 2018
    Shopfront Worker at Shopmobility.
  • I took payments, delivered scooters, managed inventory/rentals and completed data entry.

  • Feb 2013 - Oct 2015
    Tutor at charity Words & Numbers Matter.
  • I tutored students with learning difficulties in English, Maths & Reading.

  • 2022 - 2023
    Master's Thesis in Chemical Physics, University of Oxford.
  • Classification: Distinction | Mark 78%

    My master's thesis focused on utilizing molecular simulations to simulate rod-like particle phase behaviour. These simulations were performed using Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS). The particles were modelled as a collection of hard spheres and molecular interactions (depletion interactions) as Lennard-Jones potentials. This generated phase behaviour similar to the experimental and theoretical literature of these systems.

  • 2018 - 2023
    Master's Degree in Chemistry, University of Oxford.
  • Classification: First Class Honours | Mark: 89 | Rank: 2nd

    Throughout my undergraduate degree, I particularly enjoyed highly mathematical modules such as Quantum Chemistry, Statistical Mechanics & Thermodynamics. As a chemist many of the systems studied where highly complex chemical & physical systems. To predict and rationalize behaviour for these systems you are required to clearly define model assumptions and then use the key patterns of your data/theory. It was always important to understand the margin of error and level of predictability that your model could provide and in addition where the model breaks down.

Portfolio

This past year I have dedicated a large portion of my spare time to mastering Python and learning data structures & algorithms.

During my spare time by solving problems and building projects I have learnt a number of core programming principles. While building my space invaders & tetris games, I learnt the value of writing short clean code and refactoring code. This has enhanced my ability to understand the code I have previously written, deal with bugs and iterate on this code. Another important skill I have learnt is how to break down problems into smaller subproblems through techniques such as helper functions, recursion and divide & conquer.

Below are some details and links to my github repositorys.
