About me
Intro
I'm Josh, a software engineer with 6+ years building scalable, production-ready products across mobile, backend, and AI. I design and ship high-impact features end-to-end: from performant React Native apps and React/Next.js frontends to robust FastAPI/Node backends and LLM-powered systems that enable personalised, retrieval-augmented experiences. My work sits at the intersection of product and engineering. I've led performance and architecture improvements (including a 35% app performance lift), integrated vector search and RAG pipelines using LangChain, Weaviate, and Pinecone, and built real-time event-driven systems with Kafka and WebSockets. I deliver secure, observable platforms using TypeScript, Python, PostgreSQL/MongoDB, Redis, Elasticsearch, Docker, Kubernetes (EKS/GKE), Terraform, AWS/ GCP, and CI/CD (GitHub Actions/Argo). I also implement monitoring and SRE practices (Prometheus, Grafana, OpenTelemetry, Sentry) and follow security best practices (OAuth2/OIDC, JWT, secret management). I bring a product-oriented mindset, clean engineering practices, and a passion for solving real problems with AI and great design. Open to Fullstack, Mobile, or AI engineering roles, technical leadership, and collaborations that push boundaries. Let's connect and build the future together.
