Experience: 3+ years
Backend Engineering
ML Engineering
Cloud & DevOps

I'm a software engineer focused on Python backend systems, ML engineering, scalable APIs, and cloud-native infrastructure ☁️. I graduated with honors from New York University Abu Dhabi 🏫 with a B.S. in Computer Science and a minor in Mathematics. As a Founding Software Engineer at Calvyan, I build and maintain microservices, API gateways, and CI/CD pipelines running on Google Cloud 🚀. I've also built payment integrations and webhook systems at Buzz Mobility, and built ML systems for the open-source Comunica SPARQL engine — vector embeddings, semantic retrieval with Milvus, and gRPC-backed query pipelines for federated RDF at scale. Beyond coding, I'm passionate about photography 📸. I love capturing moments, framing stories through the lens, and finding inspiration in the world around me. As I continue my professional journey, I'm excited to keep pushing boundaries, building reliable systems, and weaving creativity into everything I do.
