About Hery

Expert Fullstack Developer in AI & Automation | Flutter, Next.js, Supabase, n8n
Do you have complex business processes slowing down your growth? I design intelligent solutions that automate your operations and amplify your productivity with AI.
I transform your workflows into fullstack applications coupled with automation. Document extraction, automatic routing, AI agents, field optimization – I deploy intelligence directly into your processes.
My achievements in AI & Automation:
Autonomous Delivery V2: Web-to-mobile solution with OCR and AI agents for automatic recipient identification, intelligent routing, report generation. Fully automated flow.
Annexx Staff: Internal application + n8n for real-time synchronization, geolocation, AI agents analyzing field operations with intelligent alerts.
n8n Platform: Central automation server decoupling workflows from business logic. Multiple integrations, complex orchestration without additional code.
Specialized AI Agents: Development of conversational and analytical agents by department – customer support, risk analysis, business insights extraction.
What sets me apart:
Expert in applied AI in production: OCR, document extraction, AI agents, integrated LLMs. No theory, real implementation. Master of automation with n8n and sophisticated workflows. Fullstack expert: Flutter mobile, Next.js web, Supabase backend. Product-minded engineer thinking business impact first.
I work on: complex workflow automation (logistics, operations), AI agents integrated into your processes, offline mobile applications coupled with automation, modernization with intelligent orchestration, secure and compliant solutions.
