1/ End-to-End Application Development & Deployment

• Engineered and deployed 'ohyaml', a high-traffic quiz application built with React, TypeScript, and Next.js that scaled to serve 26,000+ users.
• Developed and launched a DevOps-themed Wordle game with React, Typescript and Next.js getting over 3000+ users.

2/ Backend Service & API Development

• Architected and developed a Model Context Protocol (MCP) server in Python, implementing REST API endpoints to standardize and transform observability data streams.
• Designed and configured complex OpenTelemetry Collector pipelines using YAML to aggregate, process, and route high-volume telemetry data (traces, metrics, logs) to backend analysis platforms like SigNoz.

3/ Cloud-Native Observability & Instrumentation

• Spearheaded the implementation of end-to-end observability by instrumenting polyglot applications, CI/CD pipelines, and live Kubernetes clusters and Docker containers with OpenTelemetry.

4/ Technical Content & Authorship

• Authored over 15 in-depth technical articles and produced multiple video tutorials on OpenTelemetry, Kubernetes, and CI/CD. A blog post on YAML-based observability configurations went viral on Hacker News, attracting over 100 upvotes and driving 15,000+ pageviews.

1/ Optimized Data Processing & Cloud Costs

• Architected a high-throughput data pipeline migration from AWS Athena to PySpark, optimizing the processing of over 1TB of multi-tenant data. This initiative reduced data processing time by 40% and slashed AWS storage costs by 25%.

2/ Full-Stack Feature Development

• Engineered and launched critical front-end features, including a website-tracking dashboard and a timezone-aware settings page, using React, Redux, and TypeScript. These enhancements directly contributed to a 15% increase in user engagement and improved overall user satisfaction.

3/ API & Automation Development

• Developed and deployed a suite of email automation features (BCC, CC, preheader) using a Python, Flask, and MongoDB (PyMongo) stack. The system automated workflows for over 500+ campaigns, reducing manual effort by 30% and improving configuration efficiency.

4/ Distributed Systems & Event-Driven Architecture

• Engineered resilient Kafka consumers to process asynchronous events, triggering gRPC calls for automated column deletions in SingleStore (via SQLAlchemy). Implemented robust error handling with SQS-based delayed retries and Dead Letter Queues (DLQs), boosting system fault tolerance.

5/ Cloud Infrastructure & Scalability

• Architected the migration of an asynchronous job system from Celery Beat to a scalable AWS SQS-based solution with a custom scheduler, achieving a 30% improvement in job processing efficiency and enhancing system reliability.
• Designed and implemented a serverless feature flag system using AWS Lambda, enabling dynamic, scalable, and targeted feature releases across a multi-tenant architecture, significantly reducing deployment risks.

6/ Database Management & Migration

• Spearheaded a critical database migration, executing scripts to seamlessly add new columns across all production tables in a multi-tenant SingleStore environment. Ensured zero downtime and maintained 100% data integrity during the transition.

• Engineered and deployed a Python-based Discord bot to integrate with the GitLab CI/CD pipeline, utilizing the Discord APIand GitLab webhooks. The bot delivered real-time notifications of code commits and merge events, improving visibility into the development lifecycle and streamlining the code review process.
• Created a chrome extension leveraging Beautiful Soup to scrape and summarize data from their site, improving accessibility and efficiency of data retrieval.

• Built the official website for GirlScript, Kochi using HTML, CSS, and JavaScript, handling the entire process from design to implementation, resulting in a 20% increase in web traffic within the first three months.
