Senior AI Agent & Full-Stack Dev | Python, NodeJS, Next.js, React, AWS

I build software that makes clients look premium, move faster, and leave their competitors behind. Not prototypes. Not demos that break the moment real users arrive. Production systems that ship, hold up under load, and make people say "who built this?" If your project is stuck, half-finished, or about to launch and you need someone who will take it seriously and finish it, you are in the right place. WHAT I BUILD 🚀 Launch readiness Your product goes from "almost ready" to live and safe. Code review, security and auth hardening, Stripe subscriptions and billing tiers, prototype storage migrated to a real database, deployment, and a clean handover your next developer will thank you for. 🤖 AI agent systems Multi-agent workflows with LangGraph and LangChain, human-in-the-loop approval flows, tool calling, background workers and scheduled jobs, plus memory layers that give agents real context continuity across vector, graph, semantic, and episodic stores. AI that works in production, not just in a screenshot. 🌐 Full-stack products Next.js and React frontends, Python or Node backends, PostgreSQL, authentication and role-based access, admin panels, and third-party integrations. Built clean, built to scale, built so you are not rewriting it in six months. 📱 Mobile Flutter apps for iOS and Android from one codebase. Offline-first local-to-cloud sync for low-connectivity users, biometric and health data integrations, and interfaces that feel native, not generic. ☁️ Cloud and infrastructure Serverless AWS and GCP architecture, Docker, CI/CD. One system I rebuilt cut mobile load times by more than 60 percent. 🏆 WHY CLIENTS KEEP ME AWS Certified Solutions Architect Associate and Cloud Practitioner. I design for scale, not just deployment. I have shipped production platforms with 120+ API endpoints, multi-stage AI pipelines, real-time systems, and payment flows handling real money. I have found bugs in production that other developers walked straight past, including a Stripe webhook race condition that would have charged users twice. I am a team member behind the design and implementation of the A2SV app, live on Google Play. My clients do not just get working code. They get a product that raises the standard of their entire business. 🧰 STACK Python (FastAPI) · Node.js · Go · TypeScript · React · Next.js · NestJS · Electron · Three.js · Flutter · LangGraph · LangChain · CrewAI · Anthropic and OpenAI APIs · n8n · PostgreSQL · MongoDB · Supabase · Prisma · Drizzle · Pinecone · Redis · Stripe · Docker · AWS (Lambda, S3, EC2, ECS) · Google Cloud WORKING WITH ME ✅ Milestone breakdown with a price attached to each one, agreed before I start ✅ A realistic timeline, and an early heads-up if it moves ✅ GitHub with regular, readable commits ✅ An honest assessment upfront, including when your project does not need what you think it needs ✅ Available for long-term retainers, ongoing maintenance, and part-time collaboration ✅ Comfortable overlapping with US and European hours, including daily sync blocks I finish what I start.
