I’m a senior Full-Stack & AI Engineer with extensive experience designing, building, and scaling production-grade software across AI automation, SaaS platforms, data pipelines, and high-volume e-commerce systems. I approach every project with both an engineering and business mindset, ensuring solutions are not only technically sound but also practical, maintainable, and ROI-driven. ✓ What I do best – AI & Automation • LLM integrations (OpenAI, RAG pipelines, embeddings, copilots) • Intelligent workflow automation and data processing • AI-powered internal tools and dashboards – Backend & Data Engineering • Custom APIs and event-driven architectures • PostgreSQL at scale (partitioning, optimization, analytics) • ETL pipelines across Shopify, Salesforce, ERP, and custom systems • Node.js, Python, TypeScript – Frontend Development & UX • Modern, responsive frontends built for real users • React, Next.js, and component-driven UI architecture • Data-heavy dashboards with performance in mind • Clean UI/UX that balances usability, speed, and clarity • Frontends tightly integrated with backend and analytics layers – Mobile App Development • Cross-platform mobile apps (iOS & Android) • React Native, Flutter, and modern mobile stacks • Secure API integration and real-time data sync • Apps designed for performance, stability, and growth – Cloud, DevOps & Reliability • Docker / Podman, CI/CD pipelines, secure deployments • Observability, logging, and performance tuning • Systems designed to scale without constant maintenance ✓ How I work • Clear communication and structured milestones • Production-ready code — no shortcuts or fragile builds • Proactive technical guidance when I see risks or better paths • Long-term thinking: solutions that grow with your business Clients bring me in when systems become too complex, too slow, or unreliable, or when an AI idea needs to become a real, production-ready product — not just a prototype. If you need a senior engineer who can own frontend, backend, data, and AI end-to-end, and deliver clean, scalable results — let’s build it right. less
