ABOUT IFTIKHAR LIAQUAT
I graduated with a Bachelor\'s in Software Engineering from the University of the Punjab - PUCIT, where I earned a spot on the Principal’s List and won First Place in a nationwide software competition. My academic journey cultivated a deep curiosity for problem-solving and cloud technologies, laying a strong foundation for a career in data engineering. I’m passionate about building smart, scalable systems that empower businesses through data.With over 7 years of experience in the tech industry. I’ve led and delivered high-impact projects across domains like marketing, cloud cost optimization, and finance. At HelloFresh, I spearheaded the Data Modernization Initiative, optimizing global data pipelines and reducing AWS costs by ~53%. I’ve worked extensively with AWS, BigQuery, Apache Spark, Airflow, and Kubernetes to build resilient, cloud-native architectures. My experience spans building ETL pipelines, microservices, and automation frameworks, and I thrive in agile environments using Scrum and Kanban.I aim to keep growing as a technical leader, contributing to cutting-edge data platforms that solve complex real-world problems. My future goals include driving large-scale cloud migration and optimization strategies, mentoring teams in best engineering practices, and leading projects that push the boundaries of what\'s possible with data. I\'m especially excited by the intersection of cloud infrastructure and big data—where performance, scalability, and cost-efficiency AWS Cloud Expertise IAM Roles and Policies• EC2, S3, Lambda, Cloud Storage• ECS, EKS, RDS, Redshift• CloudWatch, SNS, SQS• Cognito, SSM, API Gateways• Auto Scaling, Elastic Load Balancer, Route53• Code Pipeline, Code Commit, Code Build• AWS EMR, Google Dataproc• AWS Glue for ETL, Step Functions, and much Big Data tools Expertise Data Processing Frameworks: Apache Spark, Apache Hadoop, Apache Kafka• Data Warehouses: AWS Redshift, Yandex ClickHouse, Big Query• SQL Stores: AWS MySQL, AWS PostgreSQL, AWS Aurora PostgreSQL• NoSQL Stores: AWS DynamoDB, MongoDB• In-memory Store: Redis• Containerization & Orchestration: Docker, AWS ECR, AWS EKS• Kubernetes: Services, Pod Autoscalling, Cron Jobs, HPA• Monitoring & Logging: Cloudwatch, DataDog, Elasticsearch, Kibana• Languages: Scala, Microservices Scala + Vertex- Kotlin + Spring Boot + Swagger- Kubernetes- Python- Unit & Integration Testing Testcontainers
