Backend and Full-Stack Engineer with 6+ years of production experience designing, building, and scaling distributed microservices, RESTful APIs, financial reconciliation engines, and real-time media streaming backends using Python (FastAPI, Django, async SQLAlchemy), Node.js, PostgreSQL, Redis, RabbitMQ, and AWS.

Over the past year, I have operated a fully AI-Native & Agentic engineering workflow — using Claude Code, Codex, Cursor, Google Antigravity CLI, Factory Droid, and Pi coding agent as daily multipliers for spec-driven architecture, multi-agent orchestration, Model Context Protocol (MCP) tool integration, and automated verification loops.

• Agentic AI & Multi-Agent Systems: Claude Code, Codex, Cursor, Google Antigravity CLI, Factory Droid, Pi coding agent, Model Context Protocol (MCP), multi-agent orchestration (Anthropic Claude, OpenAI, Google Gemini), structured output validation, retry/fallback routing, evaluation harnesses
• Backend & APIs: Python (FastAPI, Django, async SQLAlchemy), Node.js (Express), PHP (Laravel), RESTful API contract design, microservices architecture, RBAC authentication
• Databases, Caching & Queues: PostgreSQL, MySQL, MongoDB, Elasticsearch, Redis, Memcached, RabbitMQ, batch & incremental data synchronization
• Cloud, Media & DevOps: AWS (S3, EC2, EKS, VPC, CloudFront, Kinesis Video Streams), Docker, Git, Linux, CI/CD & automated testing harnesses
• Frontend: JavaScript (ES6+), React.js, HTML5, CSS3

• Microservices-Based Enterprise ERP Platform (7+ Core Services): Architected and maintained 7+ independent services including User & RBAC Auth, Employee Profile, S3-like Resource & Media Storage, Async Notification (RabbitMQ/Redis), Real-Time Internal Chat, Quarterly Labor Analytics, and Royalty Management.
• Automated Royalty Calculation & Media Plagiarism Detection: Built an automated calculation engine factoring page views, word count, content category, and attached media; integrated a custom image/video processing model to verify originality and detect duplicates before payout distribution.
• Internal Accounting & Financial Reconciliation Software: Engineered multi-source financial recording, batch reconciliation, and audit reporting pipelines with comprehensive automated test suites built via agentic coding workflows.
• Eduzone FastAPI Backend & Live Video Streaming: Developed the core RESTful backend (Python, FastAPI, async SQLAlchemy) and a live-streaming video backend powered by AWS Kinesis Video Streams and MongoDB.
• E-Commerce CMS & Order Workflows: Built administrative catalog, content, and order management systems backed by PostgreSQL and Laravel.
