cat about.txt

Engineering leader who builds systems and the teams behind them. Currently scaling operations across European markets while keeping hands on the keyboard. I believe good architecture and good culture are the same problem viewed from different angles.

Experience

Staff Engineer & EM @ Tide 2025 → present

Leading 2 cross-functional teams (15 engineers, 2 PMs) for European and India expansion — defined target architecture for multi-market operations and shipped France launch September 2024
Championed continuous deployment practices, increasing releases from 5-6/week to 10+/day and reducing incidents from 5-6/week to 2-3/month by shrinking blast radius to single-PR scope
Consolidated 4 fragmented services into a unified lender domain, replacing duplicated regional codebases with a configuration-driven approach — enabling a consistent, globally-focused platform
Enabled engineers to own end-to-end delivery of cross-cutting initiatives, providing sponsorship and architectural guidance without becoming a bottleneck

Senior Software Engineer II @ Omnipresent Group Nov 2023 → Dec 2024

Standardised service deployments on AWS with blue/green support, replacing error-prone manual processes — architecture adopted company-wide (~50 engineers) with teams owning their pipelines through composable, versioned GitHub Actions
Established shared Python library pattern where none existed, serving 3 teams (~20 engineers) — enabled contract-driven development and reduced cognitive load by encapsulating changes into testable, versioned components
Integrated 4-5 payment providers into a unified payments service enabling cross-platform transactions for employers and contractors

SRE / Software Engineer @ GoCardless Sep 2021 → Jun 2023

Optimised CI pipeline by reducing container images from 3-4GB to ~500MB and relocating GKE registry to avoid cross-region transfer — saving ~$120k/year
Built internal knowledge base adopted by 200+ engineers, reducing long-running support tickets from 50-60 to 10-20 prioritised items, and weekly tickets from 20-30 to ~10
Upgraded 3 GKE clusters (prod, staging, dev) to modernised Terraform modules with zero downtime
Developed Open Banking gateway integrating major UK and German banks via Yapily and Salt Edge, enabling direct bank connections for internal payments service
Designed and shipped cross-region recurring payments API — UK variable recurring payments implementation followed from Australian specification

Software Engineer @ Upside Technologies Nov 2020 → Sep 2021

Replaced monolithic test suite (a spreadsheet-replicated-in-code testing all calculations at once) with BDD testing DSL — separating concerns, reducing test runtime, and enabling precise root cause identification on failures

Software Engineer @ Anaplan Jul 2017 → Oct 2020

Built v2 of Anaplan's core calculation engine — an in-memory distributed system with event-driven architecture, processing 10 trillion sparsely populated cells across a 15 quintillion cell space
Achieved 100-fold performance improvement through metrics-driven optimisation, enabling migration from dedicated data centre infrastructure to usage-based cloud deployment
Applied Information Theory and Knowledge Representation concepts to reduce computational complexity in sparse dataset aggregation
Implemented cyclic calculations with formal specification, increasing confidence in correctness without extensive manual testing
