1. Routing Next Gen

• Collaborated with a senior architect to execute the migration of NGINX routing from PKS to Kubernetes on Bare Metal (KoB), enhancing infrastructure control and aligning with long-term architectural goals.
• Contributed to the infrastructure setup and helped build GitLab CI/CD runners to automate the generation and deployment of NGINX configurations through a structured release strategy.
• Supported the integration of observability tooling including Loki, Prometheus, and Grafana, enabling real-time insights into routing performance and deployment health across environments.

2. EIROS (Expedite Incident Resolution and Optimized Solutions)

• Led the deployment of Root Cause Analysis (RCA) and incident prediction models on Kubernetes with Persistent Volume Claims (PVCs) for model storage and retrieval.
• Developed a data pipeline integrating multidimensional incident and telemetry sources, achieving a 15% reduction in MTTR and MTRS, and improving service reliability.
• Coordinated a feedback initiative with five user groups to align solutions with user workflows and pain points; received recognition for improving product line/owner identification in major incident triage.

3. SRE-AI-Hub

• Consolidated multiple internal AI tools into a unified SRE platform, featuring intelligent incident chatbots, dynamic knowledge base search, and RCA explainability, all seamlessly integrated with EIROS.
• Incorporated advanced AI techniques including RAG (Retrieval-Augmented Generation) and Agentic AI to deliver context-aware, generative responses for operational efficiency and troubleshooting.
• Built a FastAPI-based NGINX configuration generator that dynamically converts structured JSON input into production-ready NGINX configurations, supporting scalable routing for GenAI endpoints.

Infrastructure Compliance tool:

• Orchestrated the development of an application compliance tool for Pivotal Cloud Foundry within Dell Technologies' SRE team, leveraging Cloud Foundry APIs for seamless platform interaction and implementation of necessary updates.
• Successfully deployed the application across seven domains, facilitating the onboarding of over 7000 applications and microservices. This initiative streamlined developer efforts by an impressive 82% and elevated compliance standards to a perfect 100% within a span of six months.

SRE Dashboard

• Championed development of a pivotal Sales Events and Executive Dashboard crucial for real-time decision-making during peak holiday seasons, empowering business teams with actionable insights for swift product procurement decisions.
• Pioneered the introduction of several new capabilities to the dashboard, enhancing its functionality to cater to a peak of 900 active users and seamlessly integrating it into the business workflow.
• Oversaw the transition to OMCS (Order Management Cloud Services) APIs for standardized access to sales data, driving the creation of a robust Data Ingestion Pipeline capable of processing data from seven distinct segments across 17 countries.
• Directed the consumption and standardization of data using RMQ (RabbitMQ), orchestrating concurrent requests efficiently through goroutines and implementing Prometheus monitoring for optimal system performance and reliability.
• Facilitated the tracking of various order statuses such as Released, Held, and Cancelled orders, ensuring the dashboard met the precise needs of both consumer and business users with precision and agility.

• Developed and maintained robust data pipelines in StreamSets, enhancing data collection, processing, and storage efficiency while implementing quality checks and anomaly detection mechanisms for 35+ dimensions of vendor data files.
• Spearheaded the creation of template-based scripts and alerting mechanisms, resulting in a 45% reduction in incidents over three quarters by proactively identifying and addressing data anomalies within Dell Technologies' Data Reliability Engineering team.
