• Architected and delivered operator-centric CRM backend and multi-channel notification system in Go, processing millions of requests daily with deep integration to external platforms and identity services.
• Contributed to development of high-throughput blockchain transaction monitoring systems in Go, processing and analysing real-time data streams for trading platform operations.
• Designed and implemented critical system utilities in C, Rust, and Go, for operational workflows, monitoring, and low-level system integration.
• Managed multi-zone Kubernetes clusters across multiple cloud providers, ensuring high-availability with automated failover and load balancing.
• Led architectural design discussions and code reviews, establishing standards for code quality, style, security, and maintainability.
• Mentored Go team developers and conducted technical interviews, contributing to hiring decisions, onboarding new employees, and uplifting engineering culture and standards.

• Led infrastructure and release engineering teams, architecting deployment systems for customer environments with focus on reproducibility and zero-trust principles.
• Engineered automated FreeBSD distribution build system with custom package repository and delivery pipelines.
• Developed performance monitoring and system utilities in C and Rust, leveraging DTrace for deep system observability and bottleneck analysis.
• Architected and deployed comprehensive CI/CD pipelines with security scanning, automated end-to-end testing, progressive rollout strategies, and heavily customised execution environment.
• Optimised large-scale FreeBSD jail orchestration, improving update efficiency and deployment speed.

• Architected and implemented high-performance DDoS mitigation system in C++, providing real-time traffic analysis and automated threat response.
• Developed kernel-level network monitoring solution using Berkeley Packet Filter (BPF) and Netmap framework in C, achieving line-rate packet processing.
• Optimised network stack and application performance through profiling and systems-level tuning whilst ensuring security and reliability.

• Architected and delivered Platform-as-a-Service (PaaS) solution, enabling both internal teams and customers to rapidly deploy and scale applications.
• Developed custom Kubernetes cluster management and automation tools, streamlining operations and reducing manual intervention.
• Reduced deployment times by 70% through CI/CD pipeline optimisation and intelligent caching strategies, eliminating vendor lock-in and enabling faster and more reliable deployments.
• Improved performance of a public video streaming platform by 80% through complete infrastructure redesign, architectural optimisation, and refactoring of legacy Java code.
• Identified and resolved critical memory leaks in core services, reducing memory footprint by 75% and eliminating cascading failures.
• Utilised OS-level virtualisation techniques with distributed storage backend, improving deployment flexibility and resource utilisation.
• Contributed to the internal Infrastructure-as-a-Service (IaaS) and Content Delivery Network (CDN) solutions, diagnosing and resolving complex system-level issues, improving system availability and reliability.

• Architected and built complete production infrastructure from scratch using FreeBSD jails, bhyve, and ZFS, with focus on security, scalability, and operational sustainability.
• Automated large-scale, declarative infrastructure and service orchestration with Terraform and Nomad, facilitating infrastructure management and service deployment at scale.
• Engineered comprehensive monitoring, alerting, and observability systems with custom tooling, providing real-time visibility into system health, performance metrics, and capacity planning.
• Optimised ZFS storage subsystem with deduplication, compression, and L2ARC/ZIL tiered caching, improving I/O throughput by 40%.
• Contributed to Java application codebase and database design, collaborating with development team on architectural decisions.
• Mentored engineering team members and participated in technical hiring, evaluating candidates and contributing to team growth.
