Software developer, technical architect, devops, team lead, and contractor with 14 years of commercial Python experience and 28 years of overall development experience, stretching back to my early teens. I specialise in end-to-end development of both large and small projects, particularly the ones focused on modelling, systems development, data warehousing & big data.Highlights of my experience include:* Algorithms and data structures, and a thorough understanding of how operating systems and hardware impact the performance and scalability of software;* With 14 years of solid, commercial Python experience I am often hired as the technical lead or architect for a project. My day-to-day routines with Python involve training and mentoring junior developers; set a technical and engineering standard with best practices in Python (and beyond).* Strict and fastidious adherent of proper release-, configuration and test management procedures. My experience with release and configuration management cover everything from home-brewed systems written with both batch and shell scripts to using Docker, Vagrant and Salt in a devops capacity. This experience extends to building large clusters of Kubernetes and Docker Swarm infrastructure and designing modern applications for a cloud and/or container-based future.* Book author of "Mastering Emacs"* Great all-round Linux skills, including versatile commandline skills.* Many years of experience writing data exchange/IPC tools, applications, APIs and web services. * Excellent RDBMS skills -- specifically Oracle/PostgreSQL.* I have excellent working knowledge of "Big Data" and Data Warehousing using a variety of tools like Cassandra, Hadoop, and Spark.

Technical ArchitectScor Jun 2017 - Jun 2021Zürich Area, SwitzerlandBrought in from London to help architect and lead the development of the Consolidated Capital Model – a Monte Carlo-driven model built from scratch and scaled to terabyte-ram-sized analyses when I left – for a front office team of actuaries and quants. I set the technical direction for the model – mostly developed by actuaries, who were beginners at Python – and ensured the resulting model met the practises expected of a modern software project: turn-key deployment from development to production and fully dockerised; complete BDD and Unit Test coverage; and a strong focus on ensuring the team wrote maintainable Python code. I trained the team in Python and helped ensure the model performance met the demands of the business. Further to the model, I also built the web application (Flask, Postgres, Celery, Docker) for running and managing the lifecycle of model runs.I acted as the primary focal point between the Business and the IT department, and ensured the team had the requisite servers and infrastructure needed to function once we went live.Following on from a successful, and on-time, release of the model, I started migrating the model to Azure, to better benefit from the scale-out facilities available in the cloud.When I joined the department did 30-40 model runs a quarter using a legacy COTS tool. By the time I left, we did 20,000 model runs in a year alone. All of it elastically scaled and right sized to the exact requirements of the model and the parameters it was given. Along the way, we added on another five actuarial models, and I built a sophisticated graph tool to analyse data inputs and outputs and optimise the order in which the models were run; when to delete output data to save space; and how to retrieve data from dozens of different data pipelines. -
