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. mindre

I’m a website security specialist focused on real-world vulnerabilities that attackers actually exploit, not just running automated scans and sending generic reports. I work with startups, small businesses, and website owners who want clear answers, not technical confusion What vulnerabilities exist on your website How serious they are How they can be fixed My approach is practical and business-driven: ✔ OWASP Top 10 security assessments ✔ Website vulnerability scanning & manual verification ✔ WordPress & CMS security reviews ✔ Actionable security reports you can actually use I’ve spent years studying how attackers think, how breaches happen, and why most companies don’t see them coming until it’s too late. That mindset allows me to test websites the way a real attacker would — carefully, ethically, and responsibly. If you’re looking for someone who: Takes your business seriously Communicates clearly Doesn’t overpromise or upsell fear Treats your website like it’s their own …then we’ll work well together. Let’s secure your website before it becomes a problem. mindre
