At 3cix, I lead development of production multi-tenant SaaS platforms, including Accelerec ATS and AI career tools. I built a seven-engine resume optimization pipeline for scoring, gap analysis, keyword injection, and section rewriting using Gemini and OpenAI.

For Accelerec, I developed ATS workflows and extended core modules of the open-source Horilla HRMS for enterprise use. I also implemented real-time recruiter-candidate chat and secure document processing with ClamAV scanning and MIME validation.

At ByTech, I developed web and React Native applications, including a mobile drop platform with live bidding, payment flows, and Firebase notifications. My projects also include an ISO 45001 management platform and a manufacturing ERP covering production, inventory, sales, and finance workflows.
