• Built a full-stack Streamlit platform from scratch, replacing a legacy Perl system, backed by a Snowflake DB.
• Owned the full SDLC: scaffolded from zero with mypy, ruff, pydantic, and testing (pytest unit and Streamlit integration), containerised the app, and shipped via internal infrastructure-as-code tooling.
• Delivered firm-wide file usage querying across AFS projects and metadata.
• Wrote data collection scripts across thousands of external Linux and Solaris hosts, aggregating on-prem before forwarding to Snowflake.
• Modelled Snowflake compute costs at petabyte-adjacent scale, designed query patterns around budget constraints, and evaluated caching strategies at scale.
• Automated the AFS release pipeline, codifying years of centralised implicit knowledge into a reproducible CI/CD flow.
• Built a pipeline taking kernel version and source RPM as inputs, using Podman to install build dependencies and compile RPMs against the target kernel, outputting distributable RPMs.
• Revived a dormant test suite, fixing failing tests and modernising dependencies to internal standards.

AFS Engineering is my current team and one I'm technologically loving. Currently leading multiple projects and learning quickly in a high-impact, large-scale environment.

• Led a department-wide SSL migration across PB applications, coordinating rollout and validation.
• Built HTTP interceptors, configured load balancers, and contributed to a secure internal gateway design.
• Solely rewrote the CSS for one of our apps, expanding its usage to mobile, per MD spec.
• Worked with the desk to author a regulatory onboarding workflow guide covering our client onboarding app.

This year was defined by a large backlog of delivery and successful project management. With leadership turnover, I stepped up to run multiple initiatives, dug into infra modernisation in an otherwise UI-focused team, built strong connections across the firm to bring improvements back to the team. I shipped a high volume of production changes, often on weekends, and helped resolve multiple production outages, building a reputation for clear-headed incident response and leadership.

• Supported Morgan Stanley's FX trading platform (Matrix), resolving production issues quickly working with colleagues and traders internationally.
• Delivered full-stack Angular + Python tools automating SRE workflows.
• Modernised legacy systems with Perl to Python migrations and RHEL server upgrades.

I'll always look back at this year fondly for sparking my interest in financial markets. Watching high-vol events - from geopolitical shocks, the JPY carry-trade unwind to CPI surprises - ripple through our books and systems brought an intense pace which I genuinely enjoyed.
