I build automated systems that replace manual workflows with AI, APIs, and custom integrations. If you’re looking to reduce operational overhead, connect scattered tools, or ship reliable full-stack features fast, that’s what I’m good at. My background: 5+ years building production-grade web/mobile apps using JavaScript and Python stacks. Recently shifted my focus toward AI-powered automation, integrating LLMs, building n8n pipelines, and connecting systems using custom Node.js integrations when off-the-shelf modules aren’t enough. What I actually deliver: • AI assistants + GPT/OpenAI model integrations • n8n workflow automation (CRM sync, lead pipelines, invoicing, notifications, task automation) • Data scrapers, API workers, background jobs • Full-stack features using React/Next.js + NestJS/Node.js • MVPs for SaaS tools, dashboards, admin portals • Custom workflow engines, API gateways, and integrations with legacy systems Tech you can expect me to use well: • JavaScript/TypeScript, Node.js, NestJS • React.js, Next.js, React Native • n8n, Zapier, Make.com • Python (FastAPI, DRF) • AWS/GCP/Azure • PostgreSQL, MongoDB, DynamoDB I’m fast, reliable, and outcome-focused — no over-engineering, no wasting time. You get clear communication, solid architecture, and maintainable code. If you want an engineer who can own the entire problem, from idea to automation to deployed product, I’m the right fit.
