2019 – Six Month Work Placement at Nested.com
In my third year of my degree I received an offer to work as a data engineer for Nested, a new, data-driven online estate agent. In my time there I have become confident with:
- Designing end-to-end data pipelines using Apache Beam on Airflow
- Business Intelligence (BI) using Looker with DBT
- Google Cloud Platform including Bigquery, Dataflow and StackDriver
I also developed my leadership skills, owning a project to build the data backend for a new automated email tool. I took the project from conception through identifying requirements, liaising with key stakeholders and implementing the final solution. At the end of the project I presented the work to the whole company during a quarterly objectives and key results presentation.
2018 – BikeSafe – Smart Concealed Bike Tracker
Second year group project designing, prototyping and programming a discrete tracking solution to allow victims of theft to retrieve their stolen bicycles. By implementing a low power design and a high capacity 18650B Li-Ion cell, a battery life of over a week was realised. A Firebase implemented Android app was developed using the Google Maps API, allowing real time overlays of bike location. Communication between the tracker and phone was achieved with GSM, chosen due to the minimal bandwidth requirements, range and low power use.
2017 – Electric Skateboard
A personal project to build a wirelessly controlled electric skateboard. I made a vacuum molded casing, housing an 8000mAh 6 Cell LiPo Battery, brushless speed controller, and radio receiver. A custom machined aluminium bracket was made to attach the 1.7kW motor to the rear truck, and taken to a specialist workshop to be welded. The skateboard reaches 20mph, but becomes quite dangerous at this speed. The range of the skateboard is 7km, and it is geared to climb hills with a gradient of up to 12%. I now use the longboard without the electronics after coming off and not wanting to risk further injury.
2016 – Ultrasonic Distance Measurer
This project uses two ultrasonic transducers and transmit and receive circuits. The transmit circuit emits a high frequency ‘chirp’ out of the left transducer. This is then reflected by an object, and detected in the right hand transducer. A series of amplifying and filtering circuits then process the received signal. By comparing the transmit and receive delay the distance of the object is calculated. No programmed ICs were used in this project, only astable oscillators, counters and logic.
