“Technically oriented operator with experience driving a strategic migration to Microsoft Azure to modernize a company toward microservices and CI/CD, improving scalability and positioning for long-term optimization. Evaluates product ideas through an operational lens (efficiency, decision support, process optimization) and emphasizes building viable products with paying customers while maintaining revenue resilience.”

“Currently working in CoRAL Lab, built and deployed IntegrityShield—a document-layer PDF watermarking system that keeps assessments visually identical while disrupting LLM-based solving; validated in a real classroom where it helped catch 12 AI-cheating cases. Also built MALDOC, a modular red-teaming platform for document-processing AI agents using LangGraph to run reproducible, deterministic adversarial trials across OCR/text/vision routes.”

“Full-stack Java engineer (4+ years) who led end-to-end modernization of high-latency order management systems into cloud-native reactive microservices (Spring WebFlux) and built real-time React/Redux dashboards, reporting 99.98% uptime and 22% infra cost savings.
