AWS Cloud Architecture
Expertise in designing and operating cloud-native platforms on AWS, including ECS, EKS, Lambda, RDS, S3, DynamoDB, API Gateway, and CloudWatch. Delivery of enterprise cloud migrations and platform modernization for SaaS startups and large-scale workloads.
Kubernetes & Container Orchestration
Hands-on experience with Kubernetes, Helm, and Helmfile for container orchestration, including migration of 40+ containerized services from Amazon ECS to Kubernetes, designing networking strategies, deployment workflows, and reusable Helm-based application templates.
CI/CD & Infrastructure as Code
Proficiency in Terraform, GitLab CI/CD, and Linux/Bash for automating infrastructure provisioning, patch management, vulnerability remediation, and standardized delivery pipelines across cloud environments.
Backend Development
Building and scaling backend APIs using TypeScript, Python, Node.js, REST, GraphQL, and event-driven microservices architectures, serving 100,000+ users with authentication, rate limiting, and real-time notification features.
Observability & Monitoring
Implementation of centralized monitoring, logging, and alerting solutions using Prometheus, Grafana, Datadog, and CloudWatch, including structured JSON logging and operational dashboards for high-volume platforms.
Database Management
Experience with relational and NoSQL databases including PostgreSQL, MySQL, MongoDB, and DynamoDB. Optimization of MySQL query latency by 40% and significant reduction of message queue processing delays.
Messaging & Event-Driven Systems
Design and implementation of asynchronous and event-driven architectures using Kafka, SNS, SQS, and Pub/Sub for real-time notifications, video processing, and high-scale SaaS platforms.
DevSecOps & Security
Design of secure and highly available AWS architectures using WAF, GuardDuty, bastion hosts, cross-account strategies, and automated monitoring and alerting. Enhancement of platform security through DevSecOps best practices.
Blockchain & Web3 Integration
Development of payment, referral, commission, and blockchain settlement systems using Polygon smart contracts and MultiSig payouts for NFT marketplace platforms generating over 1M monthly revenue.

Project history
Build, maintain, and automate secure infrastructure supporting enterprise security platforms. Develop and improve CI/CD pipelines, infrastructure provisioning, patch management, and vulnerability remediation processes. Enhance platform reliability, monitoring, and security through operational automation and DevSecOps best practices. Mentor junior engineers and accelerate onboarding through technical guidance, documentation, and knowledge sharing.
Led the migration of 40+ containerized services from Amazon ECS to Kubernetes using Helm, Terraform, and GitLab CI/CD, enabling cloud-agnostic deployments and standardized delivery pipelines. Designed and implemented Kubernetes platform capabilities, including networking, deployment strategies, release workflows, and reusable Helm-based application templates. Contributed to Architecture Decision Records (ADRs), defining platform standards for infrastructure, deployment, networking, and cloud architecture. Improved platform observability by standardizing structured JSON logging and building centralized monitoring and alerting with Prometheus and Grafana.
Participated in cloud modernization initiatives, migrating enterprise workloads from Amazon ECS to Kubernetes using Helm, Terraform, and Gitlab CI/CD. Designed and operated cloud-native platforms on AWS, improving deployment automation, observability, and operational reliability. Mentored junior engineers on cloud engineering, Kubernetes, AWS, and DevOps best practices through hands-on technical guidance and code reviews.
