About Sayak Roy

Turning complex infrastructure into intelligent automation has been the focus of my journey in technology. With over 3 years of experience in cloud, network automation, and AI-integrated systems, I work at the intersection of DevOps, SDN, and AI to create solutions that reduce manual effort, improve observability, and enhance operational performance.Current Role & Highlights: At Tata Communications, I serve as an AI Infrastructure & Automation Engineer. I have automated multi-vendor router configurations using OpenDaylight SDN Controller with NETCONF/RESTCONF APIs, cutting manual provisioning effort by 80%. I designed YAML-based OpenConfig templates for BGP, OSPF, IS-IS, and EIGRP, and built RESTful APIs that improved routing efficiency by 30%. Additionally, I developed a LEO Satellite KPI Monitoring System using distributed Raspberry Pi probes, Python scripts, and Chronograf dashboards for real-time performance visualization and historical analysis.Over the years, I have focused on merging cloud, AI, and DevOps practices into practical automation solutions. I have created AI-powered platforms like WebGrow360, a marketing automation SaaS using React.js, TailwindCSS, Node.js, Prisma ORM, and MongoDB, and a Conversational Infrastructure-as-Code pipeline that allows natural language provisioning of AWS resources through Terraform and n8n workflows. These projects reflect my interest in building intelligent systems that simplify complex operations.Key HighlightsCloud & Infrastructure: AWS (EC2, Lambda, S3, CloudWatch, API Gateway, EKS, ECS), Azure, Terraform, Ansible, AWS CDK, CloudFormation, NGINX, Docker, KubernetesNetworking & SDN: OpenDaylight, NETCONF, RESTCONF, YANG, BGP, OSPF, IS-IS, EIGRP, IRR AutomationDevOps & CI/CD: GitHub Actions, Jenkins, GitLab CI/CD, Linux, container orchestrationProgramming & Scripting: Python (Automation, Flask APIs, Web Scraping), Bash, YAMLObservability & Telemetry: InfluxDB, Telegraf, Chronograf, Grafana, Prometheus, iperf3, mtrProjects: LEO Satellite KPI Monitoring, WebGrow360, AI Chatbot & n8n Automation Pipeline, BMP Monitoring FrameworkCertifications: Google IT Automation with Python, Building Modern Python Applications on AWS, Designing and Implementing Azure AI SolutionsMy github profile: https://github.com/sayakr428I am passionate about continuing to advance AI-driven DevOps and network automation, creating solutions that make complex infrastructure more intelligent, visible, and efficient.Reach out to me at:email: s•••••••@gmail.comPhone Number:+91••••••••31

1. Cloud Engineer at Global Ip and Ethernet Engineering Team

   Tata Communications

   Jul 2023 — Present · Chennai, IN

   SDN Automation using OpenDaylight Controller Led automation initiatives using OpenDaylight (ODL) SDN Controller to manage global IP and Ethernet infrastructure. Developed and maintained NETCONF & RESTCONF APIs for real-time router configuration and telemetry integration across Cisco and Juniper platforms. Automated routing protocols (BGP, OSPF, IS-IS, RIP, EIGRP) using OpenConfig YANG models and YAML payloads.Built RESTful APIs for live data retrieval and configuration deployment, reducing manual effort and improving consistency. Integrated version-controlled YAML scripts with CI/CD pipelines for automated rollouts, with rollback mechanisms triggered by telemetry checks.Standardized cross-vendor configurations using OpenConfig structures. Reproduced complex customer scenarios in staging using Bash/Python scripting and implemented SR-TE-based Layer 2 VPN solutions for clients like Alibaba. Enabled DDoS protection across IPv4/IPv6 using BGP Flowspec and policy-based routing.Monitored traffic and system health via Kentik, Arbor, and Cacti. Enhanced network resilience and provisioning speed by automating real-time config push, telemetry validation, and service provisioning.
