An enterprise AI infrastructure platform that simplifies the deployment and management of GPU-powered, cloud-native, and virtualized applications across on-premises, public cloud, hybrid, and edge environments. It automates infrastructure operations, Kubernetes orchestration, and security governance to help organizations scale AI workloads efficiently and accelerate time to market.

• Designed and implemented zero-downtime certificate authority rotation plus certificate expiry inspection and export in Mirantis Kubernetes Engine 4, closing a customer-facing MKE 3 to MKE 4 upgrade gap and replacing manual openssl work with a single command that can be safely interrupted and resumed.
• Built an airgap-safe port connectivity check between cluster nodes, run before installs and upgrades using a lightweight probe delivered over SSH, catching firewall misconfigurations before any cluster changes. • Designed and implemented automated recovery for etcd storage exhaustion, restarting controllers one at a time without losing quorum, improving cluster resiliency and reducing operational intervention during critical failures.
• Introduced configurable resource requests and limits for MKE core services, eliminating out-of-memory failures in MKE controllers on large clusters and preventing the scheduler from placing critical workloads on overloaded nodes.

An integrated human capital management (HCM) platform that automates HR and payroll processes across the employee lifecycle. By centralizing employee data in a single database, the platform reduces manual administrative work, improves data consistency, and streamlines workflows for HR teams, managers, and employees.

• Designed and built backend infrastructure and cloud-native tooling focused on distributed systems, Kubernetes, and data processing.
• Built a database-backed work queue system for distributed task processing with strong consistency and retry semantics.
• Implemented data transformation pipelines for sensitive data, including encryption and policy-driven field processing.
• Worked with Kubernetes-based deployment workflows using Helm and GitLab CI/CD pipelines.
• Explored Kubernetes operator patterns using Kubebuilder and controller-runtime.
• Debugged controller behavior in a canary deployment operator, including reconciliation triggers, label-based filtering, and rollout logic.
• Set up and managed local Kubernetes environments, including container registries, cert-manager, and ingress controllers.
• Investigated Kubernetes internals such as CRDs, namespaces, kubeconfig authentication, and reconciliation patterns.

An open-source distributed systems platform focused on scalable decentralized infrastructure and smart contract execution, enabling secure and efficient interactions across distributed networks.

• Engineered a high-performance Write-Ahead Logging (WAL) system from scratch to ensure node recoverability and deterministic transaction replay; solved critical log-indexing and retention challenges to maintain 100% data durability across network failures.
• Architected the Go-based bridging layer between the Ethereum Virtual Machine (EVM) and IOTA's execution environment, enabling seamless deployment of Solidity smart contracts on the IOTA ecosystem.
• Designed and integrated a comprehensive Prometheus metrics suite, instrumenting core engine components to provide real-time visibility into consensus health, message throughput, and system latency.
• Designed a specialized text-based key-value store for decentralized configuration management, optimizing for high-read performance and system-wide consistency.
• Actively influenced core architecture decisions regarding BGP-like peering, fault-tolerant consensus, and resource scaling to ensure the network could withstand adversarial conditions.

An open-source digital health platform focused on delivering reliable, affordable healthcare solutions through medical software and interoperable health information systems built around medical informatics standards.

• Built new micro frontend components using React and single-spa while following best practices.
• Built and maintained backend services and APIs in Java, with a focus on scalability, performance, and maintainability.
• Worked with AWS EC2 and EKS, supporting containerized workloads and cloud infrastructure for production systems.
• Developed concurrent data-processing services backed by MySQL, optimizing queries, and application-level concurrency for throughput.
• Built a custom gallery for OpenMRS file attachments.
• Mentored junior developers.
