Hire the Best Plottable.js Specialists

I build production AI systems — multi-agent pipelines, RAG architectures, and LLM-powered automation — plus the full-stack platforms (React, Node.js, AWS) that ship them to real users. Over the past 6 years I've gone from full-stack engineer to AI engineer, and I bring both skill sets to every project: I can design the agent architecture AND build the production-grade app around it. WHAT I DO - Agentic AI systems — multi-agent pipelines with LangGraph, LangChain, CrewAI, and the OpenAI Agents SDK - RAG pipelines — hybrid retrieval (vector + keyword search), relevance filtering, and grounded/verified generation - LLM integrations — OpenAI, Bedrock, and SageMaker, deployed as serverless AWS architectures - Full-stack development — React, Next.js, Node.js, TypeScript, PostgreSQL, MongoDB - Cloud & DevOps — AWS Lambda, API Gateway, Terraform, GitHub Actions, Docker RECENT WORK - Built a distributed multi-agent system on AWS — five Lambda functions (one per agent), S3-backed vector storage, SageMaker embeddings, API Gateway orchestration, with a Next.js frontend on CloudFront + S3. - Built DocInsight, a 3-agent RAG pipeline (Relevance Checker → Research Agent → Verification Agent) that hybridizes BM25 and vector search and blocks unverified answers from ever reaching the user. - Built Sidekick, an autonomous task agent (browser, code, files, search) with a structurally independent evaluator and a typed feedback loop for self-correction on retry. - Added LangSmith observability across multi-agent pipelines — distributed tracing, automated eval suites, and CI regression gates in GitHub Actions. ENTERPRISE-SCALE FULL-STACK WORK - Built the scheduling and DST timezone engine for a workforce platform used by 11,000+ users across 170+ franchises in 4 countries — zero production shift drift across 50+ components. - Led a 5-engineer team reviving an abandoned multi-tenant social platform with no documentation, owning architecture decisions and code review. - Shipped multi-currency Stripe billing and reverse-engineered a legacy authorization system for a platform serving 1M+ end users. Tell me what you're trying to build — an AI agent, a RAG system, a full-stack app, or all three — and I'll tell you straight whether it's a good fit before we start.

Full Stack Developer — React, Next.js, TypeScript, Node.js, PostgreSQL I build production web applications that handle real business operations at scale. I'm currently a freelance Full Stack Developer, working with international clients on production systems end to end. Previously, I worked as a Full Stack Developer at an enterprise hospitality company, where I built and maintained Tipsee, a platform serving 14+ hospitality venues. The stack: React + TypeScript + Tailwind (frontend), Node.js + Express (backend), PostgreSQL (database), deployed on Vercel and Azure. I built 241+ API endpoints, integrated 11 third-party services, implemented role-based access control for 10 user roles, and automated operations with scheduled jobs and webhook processing. I use AI-assisted development tools (Claude Code, Cursor) daily in production, not as a novelty, but as core workflow tools that let me deliver faster without sacrificing quality. What I do best: Full-stack web apps — React, Next.js, TypeScript, Node.js, Express, PostgreSQL API design and third-party integrations — REST APIs, webhooks, OAuth, data pipelines UI implementation from Figma designs — pixel-perfect, responsive, Tailwind CSS Database design — schema architecture, query optimization, ETL pipelines Deployment and DevOps — Vercel, Azure, GitHub Actions, CI/CD I also build and customize apps on no-code/low-code platforms, Bubble, Lovable, Bolt, Retool, Webflow, Framer, and Airtable, when speed and cost-efficiency matter most. Let's talk about your project.
