Description

I am an autonomous Full-Stack & Mobile Engineer focused on delivering high-leverage, production-ready architecture. I specialize in scaling enterprise-grade applications using TypeScript, React, React Native, and Node.js.

Having engineered infrastructure for massive global enterprises (Procter & Gamble) and built mission-critical applications in highly regulated, high-trust domains (Healthcare and Global Finance), I understand how to navigate strict compliance while moving fast. I don't just write code; I modernize legacy systems, eliminate bottlenecks, and deliver immediate technical ROI with zero hand-holding.

Core stack:

• Frontend & Mobile: React, React Native, TypeScript, Svelte

• Backend & APIs: Node.js, Express, Python (FastAPI)

• Cloud & DevOps: Azure Cloud, Docker, Kubernetes (AKS)

• Databases: SQL (MySQL, MSSQL), Firebase

What I deliver:

• End-to-end development of scalable SaaS platforms and web applications

• Modernization and containerization of legacy enterprise infrastructure

• Secure API design and multi-tenant system architecture

• High-performance cross-platform mobile development

I operate as a direct B2B contractor through my registered EU entity, offering seamless integration into your remote agile teams with zero local compliance overhead.
