I help companies ship production-ready AI and full-stack software faster: AI integrations, workflow automation, data pipelines, React/Node.js/Python apps, and cloud infrastructure built with senior engineering review. If you need more than a demo, I can help you turn an idea or internal process into a working product with clear scope, secure architecture, QA, monitoring, and a practical delivery plan. What I can build: - AI-powered web apps and internal tools - LLM integrations with OpenAI, Anthropic, or self-hosted models - AI-assisted software delivery workflows for product teams - Workflow automation and data pipelines - React / Next.js frontends and Node.js / Python backends - APIs, dashboards, admin panels, and SaaS features - Cloud deployment, CI/CD, monitoring, and production hardening Where I create the most value: - You have an AI idea but need a senior engineer to turn it into a real product - Your team wants to speed up development with AI-assisted SDLC without losing code quality - You need to integrate AI into an existing SaaS, CRM, marketplace, or internal platform - You need a fast MVP, pilot, or technical roadmap before committing to a larger build My delivery approach is pragmatic: - Quick discovery to define the business goal, users, risks, and success metrics - A clear technical plan with architecture, milestones, and trade-offs - AI-assisted implementation for speed, with senior human review for architecture, security, and critical logic - Automated QA, code review, and release practices so the result is maintainable - Production-minded deployment with monitoring, cloud infrastructure, and documentation Recent relevant work includes AI-assisted development process consulting, AI infrastructure planning, scalable React/API product development, and senior Salesforce/AppExchange code review advisory. I am a good fit if you want a reliable senior engineer who can move fast, communicate clearly, and deliver production-grade software instead of experiments. Send me a short brief about your product, workflow, or AI use case. I will reply with a technical plan, roadmap, and a practical MVP estimate.
