What I'm looking for

I want to build production-grade full-stack products where AI/GenAI adds real value—shipping reliable APIs and user-facing experiences, owning performance, and leveraging cloud + CI/CD to iterate fast with an engineering-first culture.

I’m an AI Full-Stack Product Engineer who builds end-to-end products—backend APIs, responsive frontends, and GenAI-powered pipelines. Recently, at Success Numbers LLC, I shipped a Flutter student academic portal with Bloc state management and delivered production Spring Boot APIs for eCommerce returns and payment workflows.

I take ownership of tricky integrations and performance: I reduced cart retrieval latency 67% through targeted DB and caching optimizations, and I built receipt pipelines for bilingual charges/B2B flows. I also blend software engineering with research—developing a spatiotemporal Graph Attention Networks + Transformers model for protein transitions—and I turn that rigor into agentic AI systems like an Airflow/LangChain RAG pipeline with drift detection and ChromaDB.
