Software Engineer | Backend & Cloud | AWS | E-commerce | AI-driven Products

Product and business-oriented Software Engineer with hands-on experience designing, building, and scaling high-impact digital platforms in e-commerce, payments, and AI-powered products. I specialize in backend engineering and cloud architecture on AWS, with a strong focus on reliability, scalability, and business metrics such as conversion, retention, and revenue.

I work at the intersection of engineering, product, and data, translating strategic goals into concrete technical decisions and sustainable solutions that deliver measurable value. Comfortable taking products from zero to production and improving mature systems operating at scale.

• Building scalable backend systems that support real business growth
• Designing event-driven and distributed architectures on AWS
• Improving checkout, payments, and conversion-critical flows
• Applying AI (LLMs & Computer Vision) to real-world, production-ready products
• Writing clean, maintainable code with strong engineering standards and CI/CD practices
• Collaborating closely with product, design, analytics, and stakeholders

I’m always open to discussing backend engineering, cloud architecture, product-driven development, and AI applied to real-world systems.

⭐ If you’re building a product where engineering quality and business impact matter, we’ll probably get along very well.
