● Manage Kubernetes clusters across development, acceptance, and production environments, including Helm-based deployments, issue resolution, operational support, and ongoing cluster maintenance. ● Serve as the sole DevOps engineer on a GDPR project, delivering infrastructure, CI/CD, monitoring, and operational support across ECS, Kong, S3, Lambda, RDS, ForgeRock, and Snowflake. ● Own platform and DevOps delivery across 3 environments (dev, acc, prod) for several greenfield projects, implementing infrastructure provisioning, deployment automation, EventBridge scheduling, PostgreSQL integration, and automated alerts for AWS Batch job state changes. ● Investigate and resolve production incidents across ECS and EKS services using Datadog and CloudWatch metrics, logs, and alerts, troubleshooting issues such as service outages, mount/permission failures, restoring availability, and coordinating with application teams where needed. ● Partner with engineering and project teams to implement secure, maintainable, and production-ready DevOps workflows while reducing manual operational overhead through automation and proactive platform maintenance. ● Build and maintain CI/CD pipelines for infrastructure and application delivery across dev, acc, and prod, improving deployment speed and release reliability. ● Migrated configuration and secrets management from AWS Secrets Manager to HashiCorp Vault, improving security, access control, and consistency across environments. ● Implement monitoring, logging, and observability using CloudWatch and Datadog, with automated alerting through Microsoft T eams and email notifications to improve visibility and incident response. ● Migrated legacy infrastructure from CloudFormation to T erraform across 3 environments, improving consistency, reducing drift, enabling repeatable deployments and fully automating infrastructure delivery ● Delivered the migration of a high-traffic service from ECS to EKS, improving scalability, reducing platform overhead, and enabling smoother release cycles.

During this period, I took a strategic career break to deepen my expertise in DevOps practices and cloud technologies. My focus was on: - Completing intensive DevOps courses, covering areas such as CI/CD, container orchestration, and infrastructure as code - Obtaining industry-recognized(AWS and Hashicorp) certifications - Hands-on projects to apply newly acquired skills in real-world scenarios - Staying current with emerging trends and best practices in cloud computing and automation This dedicated time for upskilling has equipped me with cutting-edge knowledge and practical skills, positioning me to make significant contributions in modern IT environments. I am eager to bring this enhanced skill set to my next professional endeavour and contribute to impactful projects.

- Conceptualized and executed the development of innovative features for the peer review system using Web2Py. - Developed Selenium scripts for automated testing reducing testing time from 8 mins to 3 mins and enhancing software release cycles. - Proactively engaged with end users through usability testing sessions to gather insightful feedback on the system's performance and user experience, and in turn analyzed collected data to implement targeted system improvements. - Strategically enhanced and refactored the critical second-stage workflow of the peer review system for Registered Reports to streamline processes and improve user experience. - Developed complex SQL queries to meticulously aggregate and analyze recommenders’ data, crafting a comprehensive statistics dashboard tailored for board managers.

- Managed AWS Cloud environments, automation, monitoring metrics, disaster recovery/backups, rectifying security issues, performance tuning and optimization. - Contributed to system architecture design and the migration of on-premises resources to Azure for a major pharmaceutical company, while researching PCI DSS, SOC 2, and HIPAA compliance requirements. - Eliminated 100% of downtime caused by microservices certificate issues by automating the renewal process across servers using Python scripts on AWS Lambda. - Migrated all manually configured cloud resources to a fully managed infrastructure-as-code (IaC) setup using Terraform and Terragrunt, significantly enhancing efficiency, scalability, and consistency across the cloud environment. - Designed and built a centralised monitoring system using Prometheus and Grafana to track CI/CD status across multiple projects. - Implemented monitoring and alerting systems for AWS resources with OpsGenie, resulting in early detection of system issues and a 40% reduction in the mean time to resolution for incidents. - Automated system setup, configuration and maintenance tasks using Ansible resulting in a 30% reduction in team workload and increased system reliability. - Utilized Helm for package management, Kubernetes for container orchestration, and ArgoCD for continuous delivery, gaining in-depth knowledge of cloud-native technologies. - Collaborated with cross-functional teams to troubleshoot and optimize deployment strategies, demonstrating strong problem-solving skills and teamwork. - Actively engaged in on-call rotations, providing timely and effective incident response and resolution to maintain optimal system uptime and reliability. - Developed test suites in Go for Terraform modules, ensuring robustness and reliability of infrastructure-as-code deployments.

- Architected and sustained robust RESTful APIs with Flask and Django, catering to complex business requirements for various web applications. - Developed a sophisticated Django REST API designed to ingest and analyze extensive CSV datasets of music streaming data, extracting key insights such as listener trends, genre popularity, and artist performance metrics. - Maintained and enhanced React frontend applications, ensuring high performance, responsiveness, and seamless user experience across multiple platforms. - Designed and deployed chatbots and seamlessly integrated them with cloud communication platforms, Infobip and Wati. - Collaborated in the re-engineering of APIs of an e-commerce application transitioning to a more scalable and maintainable architecture using Django. - Implemented CI/CD pipelines for a diverse portfolio of new and existing projects, leveraging GitHub CI and eliminating manual deployments. - Successfully implemented a comprehensive Social Sign-On (SSO) solution, integrating key social platforms like Facebook, Twitter, GitHub, Instagram, and Google into our application's authentication ecosystem. - Seamlessly integrated leading payment gateways, including PayStack, PayFast, and Flash, into our e-commerce platform, leveraging RESTful APIs and secure encryption protocols to ensure safe and efficient transaction processing.
