Ivan G.
Senior App Dev | Expert in [NodeJS, React, TypeScript] | Task-Base
I build and ship production systems end to end backend, frontend, infrastructure, the whole thing. Over 7+ years I've worked across healthcare, SaaS, and AI tooling, and I've owned features that real businesses run on, not just demos. My main stack is TypeScript/Node.js, React, and GraphQL, with PostgreSQL/MongoDB/Redis on the data side and Docker, Nginx, and Linux on the deployment side. I'm also comfortable in Rust, Go, and Flutter when a project calls for it. A few things I've built: an AI-powered ICD-10 search used by every provider at a US healthcare company to speed up clinical documentation and cut coding errors; an automated billing workflow that handles around 80% of that company's revenue, pulling cross-department data and delivering it to external partners for payment processing; and a feature-flag and UAT system built from scratch that the team still uses for gated rollouts. I was also a key contributor in resolving a critical production incident and consolidating infrastructure from 90 servers down to 5. Before that, I built a pet meal subscription platform as the sole developer. Next.js portal, admin dashboard, and Express/GraphQL API in a TypeScript monorepo serving 1,000+ subscribers, with recurring Stripe billing (webhooks, invoicing, failed-payment recovery), cron-driven delivery scheduling, and integrations across Stripe, Pipedrive, WhatsApp, Zendesk, and more. On the side I build things I'm curious about, like Tukod AI, a node-based AI workspace in Rust/Tauri/React with LLM streaming and vector storage. I work well async across timezones, I communicate clearly, and I don't disappear mid-project. If it involves full-stack web, backend architecture, billing/payments, or AI integration, I can probably help. Recognized with the Shining Star Award (2025–2026) for outstanding contributions. Let's build something great.
