• Architected and maintained production-grade cloud-native backend systems deployed on AWS,

supporting high-availability digital platforms with strict uptime and security requirements.

• Designed and managed scalable AWS infrastructure (ECS Fargate, ELB, CloudFront, S3, RDS

PostgreSQL, ElastiCache, VPC) to ensure operational resilience and reliable transaction

processing environments.

• Engineered cross-cloud data replication architecture from AWS PostgreSQL to Google BigQuery

using Datastream, enabling large-scale analytics pipelines and distributed data integrity across

cloud providers.

• Developed Infrastructure-as-Code frameworks (CloudFormation & Terraform) enabling rapid and

reproducible provisioning of full production environments within approximately one hour,

significantly enhancing scalability and deployment efficiency.

• Implemented automated production-like performance testing environments to evaluate system

scalability under high-load conditions, improving platform reliability and reducing operational

risk.

• Built and secured payment integration modules (Skrill, Pay by Bank) and mobile verification

backend systems to support compliant and secure financial transaction workflows.

• Developed automation scripts across Python, Node.js, Bash, and PHP to streamline infrastructure

management and reduce manual operational overhead.

• Led DevOps and systems engineering initiatives focused on uptime optimization, infrastructure

resilience, and scalable cloud-native architecture.

• Administered and optimized an enterprise-scale Atlassian Jira cluster serving over 4,000

organizational users, ensuring system reliability, performance stability, and secure access to

mission-critical project management infrastructure.

• Led large-scale lift-and-shift migration initiatives from on-premises data centers to AWS cloud

environments, modernizing legacy enterprise systems into scalable, cloud-native architectures.

• Engineered fully automated Infrastructure-as-Code (Terraform) deployment frameworks

enabling zero-manual-step provisioning across multiple enterprise application stacks,

significantly enhancing operational scalability and deployment consistency.

• Managed and optimized CI/CD ecosystems (Jenkins, TeamCity, CircleCI) and implemented

structured Release Train workflows using Node.js and GitHub Actions, improving release

predictability and deployment efficiency.

• Oversaw infrastructure hosting mission-critical applications, ensuring high availability, system

monitoring, and operational resilience under enterprise workloads.

• Contributed to scalable software deployment pipelines and continuous infrastructure

improvement initiatives, strengthening reliability and system performance.

• Administered and optimized MySQL databases, web servers, and multi-tier application stacks,

ensuring system stability, performance consistency, and secure networking configurations across

production environments.

• Designed and implemented an in-house Content Delivery Network (CDN) architecture to

optimize content distribution, reduce latency, and improve end-user performance across

geographically distributed users.

• Developed custom automation scripts and internal tooling to streamline systems administration,

improve operational efficiency, and reduce manual intervention across infrastructure

management processes.

• Delivered cost-effective infrastructure solutions aligned with industry best practices, balancing

performance optimization with resource efficiency and operational scalability.
