I’m a business process automation engineer focused on building reliable end-to-end pipelines—from diagnosing root causes to validating solutions in production. I combine workflow design, systems orchestration, and AI to turn manual operations that “took several hours” into automated processes that run in minutes.

In my current role, I designed a 165-node N8N workflow for construction-sector cost estimation automation, integrating OCR, AI-driven estimation, and automated bill-of-quantities creation via REST APIs. I built a multi-agent AI architecture with routing by trade and lot, and added anti-hallucination safeguards using SQL lookups plus price-coherence and semantic relevance checks to keep outputs dependable.

I also lead integrations that connect operational systems in real time. For example, I built an automated GAP ↔ GTS360 integration using N8N webhooks and Java backend services, including DTOs, REST controllers, mapping for 100+ projects, and error notifications—resulting in major performance and capacity improvements.

Beyond automation, I’ve implemented and optimized backend systems and automation tools across applications: OAuth2-secured REST API integrations with Keycloak, Node.js-based automated distribution via WhatsApp with authentication and rate limiting, and Spring Boot modules that improved performance, fixed critical issues, and strengthened business controls (pagination, validation workflows, and HR data integrity).
