Architected a production-grade AI Code Review Platform powered by Anthropic Claude and Google Vertex AI, processing pull requests through automated review pipelines that generated code quality, reliability, and maintainability recommendations. Developed end-to-end observability and evaluation systems to measure review effectiveness, acceptance rates, and developer satisfaction, enabling continuous improvement of AI-generated feedback and accelerating engineering velocity across teams. Engineered a high-resiliency PR Backporting Suite in Go that automates complex release cycles, integrated AI conflict analysis to provide step-by-step resolution guides, removing manual coordination for distributed teams. Optimized release reliability by implementing a multi-tier fallback system (GitHub API to native Git via GitHub Actions); reduced backporting failures by 20% and mitigated dependencies on intermittent third-party API availability. Rearchitected "Celeste" (Internal Tooling) into a receiver–processor model with queue-based retry logic; hardened the system against transient failures and ensured durable event processing across the internal ecosystem. Modernized Infrastructure-as-Code via Terraform and migrated legacy services from Kubernetes to Cloud Run, achieving a 70% reduction in operational costs while eliminating configuration drift.

Optimized core SecretScanner engine architecture, reducing CPU & memory utilization by 50% and slash false-positive rates by 80%. Designed and operated a Go-based Threat-Intel backend as a distributed system, aggregating data from 10+ sources with an emphasis on scalability and high availability. Primary maintainer of major OSS projects: ThreatMapper, SecretScanner, YaraHunter, PacketStreamer, Flowmeter. Engineered an accelerated vulnerability scanning pipeline, boosting data richness by 25% while decreasing false positives. Cross-compiled 8 Docker images for multi-arch (AMD64/ARM64) support. Developed major feature enhancements at Palo Alto HQ and represented Deepfence in customer meetings & demos. 3× International Speaker at conferences including ContainerDays (Germany) and Rejekts (USA).

About

I’m a backend and platform engineer with 7+ years of experience building reliable systems, internal tools, and cloud infrastructure using Go. I enjoy working on problems around distributed systems, automation, and making complex systems easier to operate at scale. In recent roles, I’ve worked on infrastructure automation (Terraform, Spacelift), CI/CD systems, internal services, and backend tooling. I’ve led and contributed to projects involving cloud migrations, cost optimization, and workflow automation, and I’ve collaborated closely with globally distributed teams. I care about clear ownership, good engineering practices, and building systems that are simple, maintainable, and resilient. I’m especially interested in backend or platform roles where I can work on impactful problems and continue to grow as an engineer.
