Work Experience
Full-stack Developer
Self-employed
- Handled the entire lifecycle of original titles, including design, development, release, marketing, post-release analytics, and optimization, mainly using Google Cloud and Firebase.
- Employed evolutionary algorithm-based techniques in Python to generate levels for logic-based puzzle games and optimize key metrics.
- Optimized and automated the localization process for a web-based language learning app, using the Django ORM to enable fast and cost-efficient localization in any language.
- Used Google BigQuery to analyze rich-analytics usage data and conduct statistical experiments, using remote configuration-based functionality changes.
- Developed an experimental Django Channels-based back end that implemented a TensorFlow machine learning model to provide phrase recognition for a language learning app.
- Designed, built, and released a logic puzzle game called Bikit on iOS and Android, using Vue and Capacitor.
Senior Data Scientist
Assembly
- Acted as project lead for our marketing-attribution solution, which was the team's flagship product and main revenue stream. Built bespoke implementations for various multinational brands and deployed them to production using an AWS-based stack.
- Researched purchase-path-based marketing attribution in depth and implemented all major models in the literature and proprietary models in an R package that allowed an easy application, detailed evaluation, and benchmarking.
- Worked with Google with a beta product they were developing that allowed custom algorithms in Python to be used to optimize programmatic bidding. Later won a marketing award based on the results of a trial with a large hotel brand.
- Researched and applied econometric methods to develop Mixed Media Models and implemented these in R packages, including full documentation and tests.
- Handled the experimental design and implementation of projects to measure the causal impact of marketing strategy changes, including presentation of results to clients and consultation on the next steps.
- Built AWS-based reporting pipelines taking multiple data sources to feed Google Data Studio dashboards for clients in the hotel, luxury fashion, and travel industries.
- Forecasted business metrics using cutting-edge techniques. Developed a productionized product to forecast room bookings for a large hotel client to help inform target setting for their marketing efforts.
- Provided training on SQL-based reporting for the entire organization and helped optimize and troubleshoot existing queries.
- Worked closely with the Cloud Architect to design an improved Airflow and Kubernetes-based stack for the deployment of data products developed by the team.
- Used decision tree models and feature importance techniques to evaluate ranking factors in proprietary search engines of large online retailers to inform on optimization strategies for a large consumer goods brand.
Localization Manager
Translate Plus
- Founded and grew the Localisation Engineering team to a headcount of six across multiple sites.
- Oversaw the use of computer-assisted translation (CAT), software localization, machine translation, and other technology in translation projects.
- Developed tools and processes to optimize and streamline localization workflows, which were essential for handling increasingly heavier workloads as the company experienced consistent double-figure growth.
- Created and provided technical training courses to ensure the Operations department remained highly skilled as the company grew from 20 to 150 employees across multiple sites.
