Amazon Connect | AWS Serverless & Backend Developer | Node.js, Python

I'm a senior software engineer with 15 years of experience building cloud-based applications, backend systems, and enterprise integrations. I combine hands-on development with architectural thinking and business experience, helping clients turn complex requirements into reliable, scalable software. Here's how I can help: - AWS & Serverless Development: Build backend services and cloud-native applications using AWS Lambda, API Gateway, DynamoDB, Cognito, and event-driven architectures. - Amazon Connect & Contact Center Integrations: Develop custom contact flows, Lambda integrations, backend services, and solutions that connect contact center platforms with business systems. - Backend & API Development: Build and integrate APIs using Node.js, Python, NestJS, and modern database technologies. - Enterprise Integrations: Connect platforms such as Salesforce, Zendesk, Amazon Lex, and other third-party services to automate workflows and improve customer experiences. I've worked in leadership roles, including CTO and CEO, as well as hands-on engineering positions delivering solutions for real business needs. This allows me to look beyond the code, understand the bigger picture, and make practical technical decisions. I can help whether you need someone to design an architecture, build a new feature, troubleshoot an existing system, or take ownership of a backend integration. If you have a project involving AWS, Amazon Connect, backend development, or complex integrations, let's talk about what you're building and how I can help.
