About Alex

I build fast, polished web and mobile applications using React, Next.js, and TypeScript. My work includes a React Native mobile app serving 3,000+ active users daily, enterprise DMS integrations with SAP, and AI-powered automation pipelines — all shipped and running in production.
I work with startups and mid-size companies across Europe who need reliable frontend development, clean UI implementation, or a complete web/mobile application built from scratch. Based in the EU (Bucharest, Romania), fully aligned with CET business hours, remote-first.
Core stack: React, Next.js, TypeScript, React Native, Node.js, Figma. I also bring hands-on experience with Python, Azure AI, UiPath RPA, n8n, and workflow automation.
What sets me apart: I don't just write frontend code — I've led full product builds from database design through deployment, managed release cycles across dev/test/prod environments, and integrated systems like SAP and d.velop DMS in enterprise settings.
Send me a message and I'll respond within a few hours. Let's talk about your project.

    AI-Powered Price Monitoring System
    February 2026 - Today (6 months)
    Bucharest, Romania
    Built an automated monitoring system tracking 200–400 HVAC products daily across Romanian e-commerce, alerting field agents via Telegram when competitors undercut minimum prices.
    Architected an end-to-end async Python pipeline using asyncio with semaphore-based concurrency control. The system chains web search (SerpAPI), smart scraping with a 3-tier fallback strategy (httpx → Playwright → Firecrawl with budget-managed priority queues), regex-first price extraction with locale-aware Romanian number parsing, and two-tier AI product matching using Claude API (Haiku for 80% of cases, Sonnet escalation for borderline matches).
    Implemented multi-layer deduplication, regional agent routing with sector-level granularity, Anthropic Batch API integration for 50% AI cost savings, and 24h in-memory caching. SQLite with WAL mode for concurrent reads/writes. 662 automated tests with full external service mocking.
