• Designed a multi-channel notification platform processing millions of requests daily with deep integration to external platforms.
• Designed and developed an operator-centric CRM software with a focus on integration capability with external platforms, efficiency, and extensibility per se.
• Contributed to the development of high-throughput blockchain transaction monitoring systems processing and analysing real-time data streams on the supported blockchain networks.
• Developed 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.
• Mentored Go team developers, conducted technical interviews, and contributed to hiring decisions and onboarding processes.

• Led infrastructure and release engineering teams, architecting deployment systems for customer environments with a 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.
• Developed comprehensive CI/CD pipelines with automated end-to-end testing and security scanning, progressive rollout strategies, and fully customisable build, execution, and delivery environments.
• Optimised large-scale FreeBSD jails orchestration, improving update efficiency and deployment speed.

• Developed a 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.

• Architected and delivered a public 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 a 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.
