Backend engineer with 8+ years building high-throughput distributed systems in Go and C++. Experience spans authorization platforms, log ingestion pipelines, custom network protocols, and database security tooling. Comfortable owning gRPC contracts across teams and designing for reliability and security in production.

Experience

ShopifyGolang Developer

2025 — Now

* Designed and built an RBAC authorization service in Go with role/group hierarchies and domain-scoped ABAC attributes; centralized access-control logic previously scattered across internal services.

* Owned gRPC API design for cross-team integrations with the Load Balancer and Anti-Bot platform teams; authored protobuf contracts, ran design reviews, and ensured backward-compatible rollouts.

* Implemented a transactional outbox in Go for reliable delivery to external integrations; eliminated message loss and dual-write inconsistencies between domain state and downstream systems.

* Led a security refactor of the authentication flow, binding sensitive endpoints to corporate VPN IPs; tightened access boundaries without disrupting internal users.

Palo Alto NetworksGolang Developer

2023 — 2024

* Designed and implemented a low-level TLV-based TCP protocol with batching support, achieving a 10x throughput improvement (50k → 500k logs/sec per node) by minimizing syscall overhead

* Built the high-performance log ingestion microservice on top of the custom protocol, writing data into ClickHouse at the same throughput

* Developed a microservice for streaming logs from ClickHouse to Syslog

* Architected concurrent worker pools using pipeline patterns and sequence-based polling

* Designed REST APIs for frontend–backend communication and gRPC interfaces for interaction with the network core

TwilioGolang Developer

2022 — 2023

* Designed and implemented a service for migrating mail from third-party providers into a sharded PostgreSQL cluster

* Implemented idempotent migration with checkpointing via IMAP UID, enabling safe resume after failures without duplicating messages

* Built backend services with Chi router, CORS middleware, and PostgreSQL

* Authored unit and integration tests using testify, mock, and httptest

* Built Grafana dashboards and instrumented services with Prometheus for end-to-end observability

DataSunrise, Inc.C++ Developer

2018 — 2020

United States

* Designed and implemented IaC platform to achieve easier and more flexible deployments

* Worked on parsing various SQL network protocols

* Worked with Antlr3 to parse SQL queries and built AST trees to parse metadata about them.
