Developed and maintained scalable full-stack applications using React, Next.js, Node.js, and TypeScript. Led the design of a decoupled architecture with isolated frontend (Next.js) and backend (Node.js + NestJS), boosting scalability by 50% and reducing test time by 35%. Researched, fine-tuned, and deployed LLMs and AI models to solve real business problems. Mentored 3 junior engineers, enforcing clean architecture principles and maintaining 90%+ test coverage. Managed batch training jobs and recurring workflows with Apache Airflow and Kubernetes, ensuring audit trails across the ML lifecycle. Integrated feature stores with Feast to standardize features and improve experiment speed and data accuracy. Improved CI/CD with Jenkins and GitHub Actions, embedding robust testing, security scans, and compliance checks for fast, reliable ML deployments.

Architected AWS infrastructure (EC2, S3, VPC, IAM) with Terraform and CloudFormation and automated deployments for rapid, reproducible releases. Established CI/CD pipelines in Jenkins for Node.js and Python services. Set up Docker-powered development and production environments for repeatable deployments. Integrated Nagios and Grafana for system and application monitoring, maximizing uptime. Developed backup and disaster recovery for PostgreSQL resilience. Implemented SSL/TLS, IAM policy hardening, and server patching to safeguard sensitive data. Collaborated with researchers for MVP feature delivery and wrote comprehensive internal documentation to support onboarding and scaling.

Built 15+ responsive client websites and apps using React, WordPress (headless CMS), and Vue.js. Integrated RESTful APIs (Google Maps, WhatsApp Business API, email services) and managed MySQL databases for dynamic content and form submissions. Migrated legacy PHP sites to modern React-based static sites (Gatsby + Netlify), reducing hosting costs by 60% and improving page load times by 45%.
