ABOUT DEEPAK KUMAR

As a Senior Software Engineer at HCLTech Canada, currently consulting for Mastercard, I specialize in designing scalable, observable, and fault-tolerant systems in distributed, event-driven architectures. Over the past six months, I’ve led critical initiatives to improve platform reliability, real-time processing, and infrastructure automation for a high-availability system.Key contributions include:1. Implementing full-stack observability with OpenTelemetry, Prometheus, and Grafana, replacing Micrometer to improve metric granularity and trace correlation.2. Developing dynamic Flink TaskManager autoscaling based on Prometheus alerting with advanced PromQL rules and Alertmanager inhibition logic to avoid alert flapping.3. Optimizing Flink checkpointing, operator execution latencies, and adaptive slot allocation for better throughput and fault tolerance.4. Automating infrastructure setup using Chef cookbooks, including Prometheus installation and scrape configurations, with ongoing evaluation of Chef Habitat for runtime orchestration.With over seven years of experience in the telecom, health, and enterprise domains, I bring strong technical expertise in Java, Spring Boot, AWS, Docker, and Microservices. At Bharti Airtel, I delivered critical projects such as:1. Enabling Apple Watch eSIM integration via legacy system adapters.2. Developing a WhatsApp-based chatbot that provided real-time user account and transaction support during the COVID-19 pandemic.A postgraduate in Information Technology from Douglas College, I am driven by curiosity, engineering excellence, and a passion for building systems that are not only functional but also observable, resilient, and scalable.
