Focused on company-wide product-led growth initiative, enabling a product-led sales strategy. Led design and delivery of projects including:

• Customer lifecycle automation, introducing self-signup and integration with billing provider
• Introduction of “tracking credits”, a means of controlling costs and letting customers track their usage against contract volume

Other recent efforts include:

• Implementation of branded multi-factor authentication using Auth0
• Worked with data engineering team to migrate event publishing solution to SNS/SQS, significantly reducing application developer toil and reducing cost to publish data by ~90%

• Led the design and delivery of several product features, including document upload and container detention tracking, as well as adding service level tiers in preparation for product-led growth initiative
• Bridged the gap between application and data engineers by creating tooling for generating versioned Glue Schemas from domain classes, for publishing entity changes to KDS. This led to a significant decrease in failed/reverted deployments
• Conducted programming interviews for backend engineers, and acted as onboarding buddy/mentor to the engineer ultimately chosen

• Worked on core product features using Java, Spring Boot, React, DynamoDB, PostgreSQL, Kafka, Elasticsearch
• Early contributor to design and implementation of new domain model, allowing implementation of multimodal and transshipment tracking
• Pushed for adoption of PostgreSQL over incumbent DynamoDB to fit relational nature of new model
• Back-end technical lead on winning hackathon project that was adopted in the roadmap, released, and became a core product feature (Beacon Boards)
• Supported services in-hours and during out-of-hours on-call, monitoring Grafana metrics, investigating alerts using CloudWatch, etc.

Duco is a highly scalable data automation and reconciliation platform, using React, Ruby on Rails, a Java backend for async jobs based on Akka, and MySQL.

• Contributed to the design of a data archiving system, in order to offload infrequently-accessed customer data from hot storage
• Improved the performance of bulk configuration actions from minutes to seconds
• Served rotations on third-line support, triaging and resolving customer issues
• Wrote playbooks to enable first- and second-line support staff to proactively triage alarms, reducing workload on third-line support

Worked on Sage People, a self-service HR system built on the Salesforce platform, with an Angular frontend.

• Launched a modern replacement for a core product vertical, leading the technical design of key parts of the project
• Demonstrated product enhancements in hackathons including sentiment analysis for performance reviews, UI themes for colour blind users, and an in-app feedback tool
• Mentored junior colleagues in engineering practices

My dissertation project studied the use of deep reinforcement learning for autonomous vehicle control in difficult situations, e.g. unfamiliar areas and low-grip conditions.
