I'm the CEO of NUS Technology, a software team of 75+ engineers based in Vietnam, working with international clients since 2013. Unlike typical dev shops that deliver isolated features, we design and build the core systems that power day-to-day operations: internal platforms, integrations, and automation workflows, and we stay accountable for outcomes, not just output. Over the past 12+ years we've worked closely with founders and operators (especially in Australia, the US, and Europe) on products where performance, maintainability, and business alignment truly matter. WHY CLIENTS CHOOSE US - Top Rated Agency on Upwork, 98%+ Job Success Score since 2013, 4.8/5.0 average rating - $10M+ in project value delivered - Long-term partnerships: many clients have worked with us for 5-10+ years - 75+ co-located engineers: 60+ web developers, 15+ mobile developers, plus QA, BAs, PMs, and designers WHAT WE DO BEST Operations platforms (our core) We design the central system that orchestrates bookings, payments, teams, hardware, and compliance into one seamless operation: software that bends to your process, not the other way around. We handle the integrations Zapier can't and SaaS avoids: deep data synchronization, legacy platforms, and compliance-grade audit trails where failure isn't an option. Web development - Ruby on Rails (deep expertise): production-grade apps, clean architecture, performance optimization, complex domains and high-traffic systems - Frontend: React, Next.js, Vue.js, TypeScript, Tailwind CSS - Node.js, PHP (Laravel, Symfony, WordPress), Python (Django, Flask) - RESTful and GraphQL APIs Mobile development - Native (Swift, Kotlin) and cross-platform (React Native, Flutter) for iOS and Android Cloud & DevOps - Scalable infrastructure on AWS (EC2, RDS, S3, Lambda, CloudFront), Google Cloud, Heroku - CI/CD (GitHub Actions, GitLab CI, CircleCI), Docker, monitoring and performance tuning - Cost-efficiency and scalability built in from early stages eCommerce - Shopify (custom themes, public/private apps, API integrations, migrations) - Spree Commerce, Saleor, and custom platforms when off-the-shelf doesn't fit HOW WE WORK - Outcome-driven: we focus on business results, not just shipping code - Ownership mindset: we act like a technical co-founder, not a contractor - Proactive: we surface technical debt and scaling bottlenecks before they escalate - Clear communication across time zones (we're GMT+7, with strong overlap for AU and partial US/EU) - Long-term thinking: we build systems that scale, not quick hacks that break later HOW YOU CAN WORK WITH US 1. Operations platform development: internal platforms, SaaS, workflow automation, complex integrations, replacing fragmented tools with a unified system 2. Dedicated engineering teams: backend, frontend, mobile, and QA engineers as an extended team, often for multiple years 3. Product development & MVPs: from idea to launch, fast but not fragile If you're looking for a team that thinks beyond code, challenges assumptions, and builds something that actually lasts, let's talk.

Your AI agent works in the demo and breaks at 100 real users — retrieval was never tuned, the token bill explodes, the architecture buckles. I build agent and RAG systems that hold up in production. 25+ live now, not in a demo folder. 100% Job Success, Top Rated Plus, $300K+ earned, 1,600+ hours on Upwork. Most of the people I work with are founders, CTOs, or ops leads who either need an enterprise SaaS platform built properly for the first time or have a pilot that has stalled and is quietly eating into the budget. I architect and build every system myself, with 16,000+ hours of delivery behind me across healthcare, fintech, SaaS, and real estate, so you're talking to the person who's actually designing your system, not a project manager passing notes back and forth. Most AI projects break in the same place. The demo works great. Then the first hundred real users show up, and things start coming apart: the architecture buckles under load, the token bill gets out of hand, and it turns out retrieval was never really tuned. I build to get past that point. You get a staging environment in week one, a working demo every week, and a system that holds up under actual traffic and clears whatever compliance bar your industry sets. 📊 A few recent production systems: → AI-powered SaaS for the Spanish market (Spring Boot + React) — full multi-tenant platform delivered end-to-end. → AI messaging platform with real-time voice translation. Zero to paying users in 5 weeks. → Multi-agent AI workforce for enterprise ops: four autonomous agents handling inventory, marketing, and operational decisions. → Agentic RAG processing 500+ documents daily for a financial services firm, cutting user discovery time by 93%. → Voice AI for a daycare network. Saved them $24K a year. Built and deployed in 3 weeks. → HIPAA-aware AI triage in a regulated healthcare environment, currently saving the client $300K+ annually. Also in production: RAG assistants for telehealth, LLM-based call analysis across 40+ parameters, AI agents for real estate sales teams, AI knowledge bases for clinicians, document processing for investment analysts, and real-time voice AI avatars for medical education. ⭐⭐⭐⭐⭐ "He did not simply 'deliver a project'—he architected an entire AI-powered SaaS ecosystem from concept to deployment. What sets him apart is his ability to think like both a CTO and a product strategist." — Michael McGehee, Founder & CEO at FreeTrials ⭐⭐⭐⭐⭐ "His ability to bridge strategy and innovation makes him a strong asset for any deep AI/ML-related position." — Louis A. E., CTO at GO, Founder at Web2 Web3 🔧 What I build → AI Agent Development and Multi-Agent Systems with LangChain, LangGraph, CrewAI, and MCP. Workflows with human-in-the-loop approvals, autonomous task execution, and tool orchestration. → RAG Pipelines and AI Knowledge Bases on LlamaIndex, Pinecone, Weaviate, pgvector, and Qdrant. Citation tracking, hybrid search, and the unglamorous retrieval tuning that's usually the difference between a demo and something you can actually ship. → AI Chatbots and Conversational AI on OpenAI, Claude, DeepSeek, Mistral, Llama, and open-source stacks. Conversation memory, escalation rules, and CRM or helpdesk integration. → AI SaaS and MVP Development end-to-end, on React, Next.js, TypeScript, Python, FastAPI, PostgreSQL, and AWS or GCP. → AI Voice Agents on Vapi, Retell AI, Twilio, and ElevenLabs. Real-time processing, appointment booking, CRM sync. → AI Integration and Workflow Orchestration with n8n, Make, and custom Python pipelines connecting LLMs to HubSpot, Salesforce, Zendesk, Google Workspace, and whatever else your team already lives in. →Machine Learning & Predictive Systems — NLP, computer vision, forecasting, and anomaly detection on PyTorch and TensorFlow. ⚙️ How I work Architecture, build, deploy, monitor. I lead the work end-to-end. MVPs go live in 2–3 weeks. Larger enterprise builds are structured around milestones, with weekly demos and a working staging environment from day one. Every deployment ships with CI/CD, monitoring, documentation, encrypted data handling, and 30 days of post-launch support. There's no PM filtering things. 🔒 More than engineering when you need it When a build needs it, I bring in vetted specialists: cloud and DevOps (AWS, Azure, GCP, Docker, Kubernetes, CI/CD), security and compliance (vCISO, SOC 2, ISO 27001, HIPAA, PCI DSS), and dedicated QA automation. You scope, build, secure, and test inside one engagement. 🎓 Credentials PhD in Generative AI and Reinforcement Learning (NUST). MEng in Machine Learning and Deep Learning. AWS Certified AI Practitioner. Upwork Python Skill Certified. 📩 Next step Send me a brief: what you're building, the problem it solves, and your timeline. Within 24 hours, you'll get a technical architecture outline and a straight read on scope. If you'd rather talk first, book a paid Architecture Review, and you'll walk out of the call with a written roadmap.
