Experience Highlights

Emma - Scalable AI Receptionist | Twilio Voice + GPT Realtime Model

Created a production-ready demo of an AI receptionist for Real Estate Market combining Twilio Voice and OpenAI GPT Realtime Model to handle tenant calls autonomously. 3 Phase work included live call flow, GPT-driven dialog, call routing, intent detection, dynamic GPT responses, and error-safe handoffs. I designed scalable backend endpoints and voice-tuning measures to ensure human-like cadence and reliability improving response speed and tenant satisfaction while lowering staffing needs.

OpenAI based VoiceBot Assistant - CindyApp - GPT4o - gpt-4o-realtime

My role focused on integrating advanced GPT4o Realtime Voice AI with intuitive design to deliver human-like conversations that are empathetic and engaging. I built the Demo version of this AI-powered Cindy App voice companion designed to combat loneliness among the elderly. I developed the core features, including natural voice interaction, memory recall, and a user-friendly, voice-only interface. Contributed to early validation of product-market fit and positioned tech for pilot testing and grant-based scaling.

React Nestjs Nextjs PostgreSQL WebApp for a Pharmaceutical Company

As the Lead Full Stack Software Engineer, I spearheaded the architecture, development, and deployment. I led a cross-functional team to build secure, scalable, and compliant solutions that streamlined internal workflows and enhanced operational efficiency. My role spanned front-end UI/UX implementation, robust back-end API design, Database Design for various features and cloud infrastructure setup—ensuring high performance, data integrity, and industry-specific regulatory compliance throughout the development lifecycle.

AliExpress Integrated Order Processor - Python + MongoDB

Delivered a live system that streamlines order triage: manual WordPress sync, configurable CSV import/export with preview/validation, and AliExpress tracking lookup via OAuth2. Exposed chatbot endpoints and tracking-email functionality to improve customer updates and reduce manual tracking tasks — ready for future auto-sync and scaling. I handled AliExpress OAuth2 implementation and prepared/submitted required app docs for approval, built admin controls for manual/auto tracking fetch, and implemented detailed logs for compliance and troubleshooting.

Fintech Google Sheets Add-on - Bank APIs integrated OAuth2/JWT/Stripe

The client needed a developer skilled in complex banking APIs, especially Tink—Europe's leading Open Banking platform. Using Tink’s & Plaid's OAuth2 and Node.js, I enabled secure, seamless transactions. I built a Stripe subscription flow with Stripe Prices and Subscriptions, a React UI for a Google Sheets Add-on, and leveraged Firebase Cloud Functions/Firestore. I also integrated Slack APIs for real-time alerts. Throughout, I used advanced Google Sheets Add-on features and applied JWT and Stripe checks to authenticate and regulate access, delivering a secure, scalable banking solution.
