At Tekkel AI, I designed and built a SaaS platform for AI conversational agents using Next.js, Supabase, Twilio, OpenAI, and ElevenLabs. I implemented agentic workflows with tool and function calling, LLM orchestration, and Supabase Row-Level Security policies.

I also designed a 35-table relational database schema and built integration workflows for CSV import, campaign management, and the AI call pipeline. I diagnosed production issues involving WebSocket routing, Twilio account restrictions, and data security.

At Lifetime Business LLC, I developed and maintained a SaaS platform using Node.js, React, and PostgreSQL. I introduced a Clean Architecture and MVVM structure, and designed CI/CD pipelines with Vercel for testing, builds, and production deployments.

Earlier, I built mobile applications with Flutter and worked on IoT principles at Dream Machine Technology. At TroisetPlus, I developed WordPress websites and responsive web and mobile applications, integrating APIs and creating UI/UX mockups with Figma.
