Hands-on development of production-oriented backend and AI-enabled systems, with a strong focus on architecture, performance, and operational robustness.

• Designed and implemented production-grade backend service templates using Quarkus and Fastify, including authentication, database access, and observability.
• Built a secure authentication service featuring RS256 JWTs, refresh-token rotation, WebSocket authentication, and Dockerized deployment.
• Developed scalable REST APIs for B2B self-service platforms (transaction history, document management, secure downloads).
• Implemented RAG pipelines integrating LLM APIs with FAISS and Qdrant, including semantic chunking, prompt caching, and retrieval optimization.
• Implemented custom Keycloak extensions and Prometheus plugins for security and monitoring.
• Strengthened performance-critical skills in C++ and Rust for systems-level and edge workloads.
  

Worked closely with product owners, domain experts, and developers on a next-generation education statistics platform, transitioning from aggregate to individual-level data processing.

• Translated complex domain and regulatory requirements into precise backend specifications and acceptance criteria.
• Acted as the technical interface between product stakeholders and development teams, reducing misunderstandings and rework.
• Contributed to backend architecture decisions with a focus on data privacy, scalability, and long-term maintainability.

Worked on large-scale backend systems for state-wide education platforms and digital credential infrastructure.

• Designed and implemented backend features with emphasis on reliability, performance, and operational stability.
  
• Supported cross-team coordination between frontend, backend, and external integration partners.
• Contributed to system launches and post-go-live stabilization in production environments.
  

• Technical lead for migrating an enterprise marketing platform from Teradata E?Circle to Adobe Campaign.
• Designed migration strategy and backend integration to minimize operational disruption.
  

• Architected and implemented a highly scalable XMPP-based messaging system serving millions of users across multiple brands.
• Conducted performance and load testing, leading to targeted architectural optimizations.
