• I’m currently building a large-scale enterprise search platform using React, Remix, and TypeScript, backed by OIDC (PKCE) authentication, document-level security, multi-index Elasticsearch integration, and early RAG/LLM-based search capabilities.
• What I Work On
• Designing and optimizing the frontend architecture for performance, scalability, and resilience.
• Selecting and integrating technologies that fit strict enterprise and security requirements.
• Architecting authentication flows, data pipelines, and secure information access patterns.
• Impact & Achievements
• Implemented Document Level Security on Elasticsearch to deliver personalized, access-controlled search results.
• Built multiple RAG implementations, including:
• Agentic workflows where LLMs issue dynamic tasks to dedicated data-access agents.
• Classic search-driven RAG for context-aware retrieval and enhanced user queries.
• Built a reusable component library to standardize UI patterns across the application.
• Developed Elasticsearch connectors in Python for efficient and secure data ingestion.
• Delivered backend services in Python/Django, supporting scalable search and enrichment pipelines.
• Security & Compliance
• Ensured full compliance with WCAG 2.2 accessibility standards across the UI.
• Successfully passed grey-box penetration testing, aligning with:
• NSCS guidelines for secure TLS configurations
• NIST 800-115 for technical security assessment
• OWASP Top 10 (2021) for application security best practices
• Integrated Kerberos authentication for secure access to protected enterprise systems.
