Nghia N.

I build AI agents, automation systems, SaaS-style platforms, and API-driven web applications that help businesses automate operations, customer support, sales workflows, internal processes, and data-heavy tasks. I’m a Senior Software Engineer with 8 years of professional experience building backend systems, full-stack applications, REST APIs, microservices, dashboards, database-driven platforms, and third-party integrations. My focus is not just creating a quick demo. I build practical, production-ready systems with clean architecture, reliable backend logic, database integration, authentication, error handling, logging, deployment, and maintainable code. 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 & 𝗦𝗮𝗮𝗦 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 I can also help with: • SaaS MVPs and internal business tools • Admin dashboards and customer portals • Full-stack web applications • Backend APIs and database design • Authentication, user roles, and payment workflows • Bug fixing, refactoring, performance improvement, and system cleanup 𝗔𝗜 𝗔𝗴𝗲𝗻𝘁𝘀, 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 & 𝗔𝗣𝗜𝘀 I can help you build: • AI agents for sales, support, operations, and internal workflows • AI chatbots connected to documents, websites, FAQs, CRMs, or databases • OpenAI / Claude API integrations • Workflow automation using APIs, webhooks, n8n, Zapier, or Make • RAG-based systems with document search and business logic • Custom API integrations with Stripe, Twilio, Gmail, Google Sheets, Airtable, Slack, Shopify, CRMs, and other platforms • Backend automation systems that reduce manual work and improve business operations My core stack includes Node.js, TypeScript, JavaScript, React, Next.js, REST APIs, PostgreSQL, MongoDB, OpenAI API, Claude API, Express.js, backend architecture, database design, API integrations, Docker, AWS, Azure, and Java/Spring Boot for enterprise-grade backend systems. 𝗪𝗵𝘆 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝗲𝗻𝗷𝗼𝘆 𝘄𝗼𝗿𝗸𝗶𝗻𝗴 𝘄𝗶𝘁𝗵 𝗺𝗲 • I think like a senior engineer, not just a tool operator • I can build both the AI layer and the backend system behind it • I understand APIs, databases, workflows, dashboards, and deployment • I care about reliability, security, performance, and maintainability • I focus on solving business problems, not just writing code Why so few reviews? Think of it like this — I’ve been cooking software for years, I just opened a new restaurant here 🙂 I completely understand that reviews matter, so we can start with a small “tasting menu” first. That way, you can sample how I work, communicate, and deliver before ordering the full course. If you need an AI agent, automation system, SaaS MVP, internal tool, API integration, or full-stack platform that actually works in the real world (not just in a demo video), I can help you build it properly — without the usual “it works on my machine” surprises.
