At Ethara AI, I build end-to-end AI products, spanning retrieval pipelines, scalable APIs, full-stack features, and internal tooling. My work sits at the intersection of JavaScript engineering, applied AI, and product velocity, helping the team ship fast while maintaining clean architecture and developer-friendly systems. ---------------------- What I do: - Architect and maintain production-grade RAG pipelines using LangChain, vector stores, embeddings, and custom retrieval logic optimized for low-latency answers and high accuracy. - Build Node.js microservices with modern patterns (modular architecture, typed API contracts, caching layers, structured logging, and graceful failover). - Develop high-performance frontend features in React/Next.js, focusing on reusable component design, accessible UI, and smooth async interactions. - Create AI-assisted workflows using OpenAI / Anthropic APIs, middleware prompts, and multi-step tool pipelines. - Integrate PostgreSQL + Prisma, orchestrating clean data models, migrations, relational querying, and background job flows. - Set up developer tooling for a fast-moving team—API clients, internal SDKs, utility packages, and observability hooks. - Handle authentication, session flows, secure API routes, and role-based access for user-facing and internal apps. - Work closely with founders/PMs to convert loose product ideas into shipped features with tight iteration cycles. ---------------------- Core Tech I Use: TypeScript, Node.js, Express.js, React.js, Next.js, Prisma, PostgreSQL, LangChain, OpenAI/Anthropic APIs, Redis, Docker, GitHub Actions ---------------------- My Engineering Focus: - Shipping AI-first product features backed by clean architecture. - Designing developer-friendly codebases with clear boundaries and scalable modules. - Writing predictable, maintainable, typed JavaScript/TypeScript code across the stack. - Balancing speed with engineering discipline, startup fast but enterprise steady.
