About me
I'm a software engineer specialized in designing, building and maintaining mobile and web products with Flutter as my core technology. I've worked across the whole stack — modern architectures (BLoC, MVVM), scalable Node.js and gRPC backends, serverless cloud on AWS, and AI chatbots integrated with messaging platforms — always working closely with product, design and business teams to deliver high-impact features end to end.
Backend & Cloud
Node.js, gRPC and serverless AWS — Lambda, API Gateway, SQS, DynamoDB — plus Firebase, MongoDB and Redis in production.
AI & Automation
Conversational platforms on top of WhatsApp powered by AI models, with payments, logistics and third-party integrations.
Leadership
CTO experience: technology strategy, code reviews, CI/CD culture and leading Scrum teams as the bridge between business and engineering.
