Software Engineer based in Toronto, currently building and refining products at Dialpad. Focus centers on backend reliability, high-stakes data consistency, and the development of high-velocity developer tooling.
🛠 Professional Focus
Dialpad Canada | Software Engineer, Product
January 2026 – Present
Currently managing the critical data consistency layer for Dialpad's revenue infrastructure. Work involves high-stakes orchestration between internal services and financial platforms.
- Financial Integration: Designing complex schemas and synchronization logic to bridge core services with Salesforce, NetSuite, and Braintree.
- Infrastructure: Building within a custom, in-house version of the Sanic framework, managing transactional data at enterprise scale.
- Responsive UI Building usable, intuitive billing interfaces from designs, ensuring a smooth experience for customers
- Developer Experience: Built end-to-end developer tooling to replicate production company data locally — a parallelized BigQuery → Datastore import pipeline covering 55+ entity types, SHA-256 query caching, cross-entity reference resolution, and a synthetic data generator using SDV's HMASynthesizer for PII-free test environments
🚀 Projects & Research
Hearthstore | GitHub
Open-source, disk-backed replacement for Cloud Firestore/Datastore emulators.
Engineered as a high-performance alternative to the official Java emulator. By moving storage from the JVM heap to SQLite with WAL mode, Hearthstore allows memory usage to scale with the active working set rather than total data size.
- Architecture: Multiplexed gRPC, WebChannel, and REST APIs on a single port. Converts Firestore/Datastore requests to native SQL where possible.
- Impact: Eliminated the need for heavy memory overhead in local development environments.
⚙️ Technical Arsenal
Work mostly with Python and Typescript/Javascript, but prefer C-style languages like Go and C.

Building tools that make teams move faster and with fewer blockers is the primary motivator. I like attending local shows, working on my car, driving fast and spedinng time with my cat, Gabriella.
