I’m Abi, and I live and breathe all things cloud. My time in consulting has sharpened my problem-solving skills across various tech stacks, preparing me for whatever challenges the ever-evolving cloud space throws my way. Over the years, I have engineered complex cloud-native solutions, including Kubernetes-orchestrated API gateways and multi-tiered caching strategies, to optimize performance and compliance in healthcare and enterprise environments. I have extensive experience designing resilient microservices architectures, implementing circuit breaker patterns, and managing infrastructure as code across multiple AWS regions. My work has consistently focused on improving system reliability, scalability, and security while ensuring compliance with industry standards such as PCI-DSS and HIPAA.
In my current role as a Senior Platform Engineer at Cognizant, I lead projects that integrate healthcare interoperability standards and claims analytics, serving millions of users with high availability and optimized performance. Previously, I contributed to large-scale HR and payroll systems, building event-driven microservices and middleware connectors that handle millions of daily events with robust error handling and deployment strategies. My background also includes software development with a focus on site reliability engineering, where I developed containerized MEAN stack applications and implemented zero-trust security models with role-based access control.
I am proficient in a broad range of cloud platforms including AWS, Google Cloud, and Azure, and skilled in infrastructure automation tools like Terraform and Ansible. My programming expertise spans Python, JavaScript/Node.js, Java, and Go, complemented by strong capabilities in container orchestration, CI/CD pipelines, and monitoring with tools such as Datadog and Prometheus. I am passionate about leveraging technology to build scalable, secure, and compliant systems that meet complex business needs.
I thrive in dynamic environments where innovation and continuous improvement are valued. My approach combines technical depth with a strategic mindset, enabling me to deliver solutions that not only meet immediate requirements but also anticipate future challenges. I am eager to continue growing my expertise and contributing to impactful projects in cloud engineering and platform development.
Outside of work, I stay engaged with the latest advancements in cloud technologies and enjoy collaborating with peers to share knowledge and best practices. I am committed to lifelong learning and professional development, always seeking opportunities to expand my skill set and drive meaningful outcomes for my teams and clients.
Engineered a Kubernetes-orchestrated, FHIR R4-compliant API gateway for Healthfirstโs Patient Access and Provider Directory mandates under CMS Interoperability Final Rule. Deployed HAPI-FHIR servers behind an Istio-controlled NGINX ingress and integrated OAuth 2.0 with PKCE to secure member-level access. Designed a multi-tiered Redis caching strategy tuned for payer workflows, reducing API response times during high-load periods. Developed Kubernetes metrics adapter on AWS EKS introducing custom performance signals to support independent scaling. Implemented circuit breaker patterns using Resilience4j with retry and backoff strategies to stabilize response patterns. Created multi-region Terraform and Terragrunt setup for infrastructure as code with DynamoDB state locking and Python boto3 scripts for state synchronization.
Designed and implemented microservices architecture for HR and payroll systems using AWS Lambda, API Gateway, and DynamoDB. Created event buses with Amazon EventBridge and content-based routing rules. Developed FailedEventProcessor Lambda function in Node.js managing dead letter queues with exponential backoff and Jira webhook integration. Built SAP connector middleware with Apache Camel using SAP NetWeaver Gateway and OData protocols. Implemented blue-green deployment system with Route 53 weighted routing and Lambda functions for traffic shifting and rollback. Designed compliance-as-code framework using AWS Config, Lambda, and Terraform enforcing PCI-DSS and internal standards.
Developed Docker-containerized MEAN stack application for industrial equipment maintenance with flexible MongoDB schemas. Implemented resilience patterns including Hystrix circuit breakers and retry mechanisms with exponential backoff. Established Jenkins CI/CD pipeline automating testing and deployment. Set up Service Level Objectives using Datadog with strict availability targets and performance metrics dashboards. Optimized MongoDB performance by refactoring search algorithms and creating compound indexes. Implemented zero-trust security model with RBAC using JSON Web Tokens and Express.js middleware for data isolation and scoped access.
