\vspace{8pt} % Gap between title and text

{\sl Staff Software Engineer - Full-time} \hfill February 2026 - Now \\
{\sl Senior Software Engineer - Full-time} \hfill July 2024 - January 2026 \\
Mozilla, Remote \\
Shipping Rust, C++, and Python code across Firefox desktop and mobile to hundreds of millions of users. All work is open source.
\begin{itemize} \itemsep -2pt
\item Consolidated four separate favicon implementations across Firefox teams into a single Image Service -- chose to extend an existing Python/Airflow pipeline rather than build a new microservice, now serving 4 teams from one manifest behind a GCS-backed API
\item Implemented Oblivious HTTP (OHTTP) from scratch in application-services (shared Rust component cross-compiled to Swift and Kotlin via UniFFI) plus handwritten C++ and Rust for Firefox Desktop -- users are now unidentifiable when making privacy-sensitive requests across all platforms
\item Maintained Firefox Push notification service (50k requests/second, sub-200ms latency): reduced memory footprint, added circuit breakers, and built Grafana dashboards for operational visibility
\item Contributor and code reviewer for UniFFI, Mozilla's multi-language bindings generator enabling Rust code to be called from Kotlin, Swift, Python, and JavaScript
\item Built Rust extensions for Merino (Python/FastAPI service powering Firefox Suggest); wrote RFCs, mapped out project plans, and surfaced cross-team blockers early
\item Led ``Rusty Fridays'' internal education sessions, guiding engineers through Rust adoption and mentoring junior contributors across teams
\end{itemize}

{\sl Senior Systems Engineer, Team Lead - Full-time} \hfill April 2023 - June 2024 \\
Toposware, Remote \\
Core team of 4 building a peer-to-peer distributed network protocol from scratch in Rust.
\begin{itemize} \itemsep -2pt
\item Achieved 10x throughput per node by profiling and targeting the actual bottleneck -- optimized batch processing and serialization paths, tuned message volumes to avoid throughput degradation -- rather than redesigning the consensus layer
\item Led benchmark initiative with 3 engineers that revealed nodes were compute-bound on crypto operations, not network-limited -- redirected optimization effort accordingly
\item Rewrote the CLI from scratch, replacing error-prone CLI parameters with local config files -- reduced operator misconfiguration during node setup
\item Built an EVM bridge connecting external Ethereum-compatible chains to the core network
\item Set up load testing, CI/CD pipelines, and Grafana dashboards for production observability
\end{itemize}

{\sl Senior Software Engineer - Full-time} \hfill August 2022 - February 2023 \\
Centrifuge, Remote \\
Protocol team building DeFi applications on Substrate/Polkadot in a self-governed organization.
\begin{itemize} \itemsep -2pt
\item Implemented fund pool mutations on-chain, enabling users to adjust capital allocations in live pools -- core feature for the lending protocol
\item Built client-facing APIs on top of fund pools, giving external integrators programmatic access to pool operations
\item Replaced manual documentation with CI-driven auto-generation from Rust source on every PR -- eliminated persistent drift between code and public docs
\item Co-authored RFCs to build consensus on new protocol features across the decentralized team
\end{itemize}

{\sl Author of "Rust Web Development"} \hfill October 2020 - December 2022 \\
Manning Publications, Remote \\
\begin{itemize} \itemsep -2pt
\item Published ``Rust Web Development'' through Manning -- end-to-end guide covering async Rust, web frameworks, and production deployment, distributed globally
\end{itemize}

{\sl Sr. Solutions Architect (Professional Services) - Full-time} \hfill May 2021 - July 2022 \\
{\sl Solutions Architect (Professional Services) - Full-time} \hfill June 2020 - May 2021 \\
Twilio Inc., Remote \\
Second Solutions Architect hired for the new EMEA Professional Services team. Led enterprise integrations across contact center, messaging, and voice products.
\begin{itemize} \itemsep -2pt
\item Technical lead for Fortune 500 engagements: debugged audio quality and latency issues, redesigned messaging flows, and advised clients on achievable architectures given their team size and resources
\item Advocated for combining two existing lower-cost Twilio products over adopting a newer, more expensive one for a major engagement -- reduced client spend while using battle-tested components
\item Created reusable engagement playbooks (setup checklists, edge-case discovery questions, technical review templates) adopted across the EMEA team
\item Hired and onboarded engineers to scale the Professional Services team
\end{itemize}

{\sl Systems Engineer - Contract} \hfill August 2019 - May 2020 \\
Kraken Digital Currency Exchange, Remote (San Francisco)\\
Member of the first Rust engineering team (12 engineers), replacing core banking infrastructure and API gateway.
\begin{itemize} \itemsep -2pt
\item Migrated core banking services and API gateway from PHP to Rust, achieving 100x throughput improvement -- enabling the exchange to absorb order-of-magnitude traffic growth without scaling hardware
\item Built new Rust services from scratch with comprehensive test coverage and security-first design
\item Worked directly with the CTO on privacy-focused architectural decisions for the trading platform
\end{itemize}

{\sl Rust Developer - Freelance} \hfill March 2019 - July 2019 \\

Freelance consultant for enterprise clients across IoT, logistics, tourism, and ad-tech.
\begin{itemize} \itemsep -2pt
\item Designed authentication infrastructure for OSRAM's IoT platform (thousands of connected lighting devices) using Keycloak for user auth and service-to-service auth across microservices (Node.js, Go, Lua)
\item First engineering hire at K\"orber Digital: chose Node.js/React/AWS stack, built real-time data pipelines with a time-series database optimized for fast retrieval of sensor data
\item Decomposed GIATA's monolithic tourism ERP into 6 Docker-based microservices -- rewrote the hotel ingestion pipeline and mass photo upload system, significantly improving UI responsiveness and system scalability
\item Tech Lead at Avenga: introduced Scrum and refactored a monolith into microservices to unblock parallel team development
\item Built analytics dashboards and ad platforms at Glispa (AngularJS); mentored teams on modern JavaScript practices
\end{itemize}
