What I'm looking for

I’m looking to build AI-powered platforms and governed agent workflows—rapid prototyping with LLMs, productionizing full-stack systems, and improving reliability, performance, and auditability for enterprise teams.

I’m a Senior Full Stack Engineer with 10+ years delivering AI-powered platforms, web systems, and developer tools across high-growth startups and enterprise environments. I specialize in AI-native workflows—rapidly prototyping, validating, and productionizing AI systems using LLMs, agent frameworks, and modern developer tooling.

Across 9+ years of SDLC experience, I lead from requirements analysis through design, development, integration, maintenance, installation, implementation, and testing of client, server, and web applications. I’ve built solutions that reduce turnaround time and improve cross-team collaboration, including AI consoles with live visualization and prioritized diagnostics.

My background spans deep frontend and backend delivery: 6+ years with React, Angular, Vue, and CMS platforms (WordPress, Drupal), plus 4+ years with Node.js, Express.js, Django, FastAPI, Laravel, and GraphQL. I also work confidently with relational and NoSQL data—MySQL, PostgreSQL, MongoDB—along with event-driven and real-time systems.

Recently, I’ve focused on governed agentic AI: orchestration and observability platforms for autonomous agents, MCP-powered interoperability, incident monitoring, and secure, auditable workflows. I’ve also integrated trust mechanisms using blockchain-based audit logging (Hedera Hashgraph) to support tamper resistance and regulatory-grade audit readiness.
