⭐ National Champion & Gold Medalist in AI (TESDA Skills 2026) | ASEAN International Qualifier

Need to deploy production AI microservices, build custom RAG pipelines, or ship high-performance Next.js web applications?
I am a Software & AI/ML Engineer who bridges the gap between machine learning models and scalable, production cloud systems. I don't just build Jupyter notebook prototypes—I architect and ship production code with automated CI/CD pipelines.

What I can build for you:
• Generative AI & Agents: Custom RAG pipelines (LangChain, LlamaIndex), multi-agent systems (CrewAI, LangGraph), and prompt evaluation (LangSmith).
• Machine Learning & Edge AI: Fast inference pipelines, model optimization (ONNX, OpenVINO, PyTorch), and data engineering (Polars, Pandas).
• Full-Stack Web Development: Scalable web apps with Next.js 15, TypeScript, Tailwind CSS, FastAPI, and PostgreSQL.

Proven Track Record:
• Gold Medalist — TESDA National Skills Competition 2026 (Artificial Intelligence)
• Shipped 4 production web apps for US clients (CITC), boosting load speeds by 30–40%.
• Built an end-to-end edge AI alert system under timed competition constraints (95.76% accuracy).

Have a project in mind? Send me an invite and let's discuss your timeline and architecture.

Full stack web and mobile developer, building production applications since 2022 in React, Next.js, Node.js, Laravel, and React Native. Looking for a long-term role with one employer, not short contracts.

One hire covers your frontend, backend, database, integrations, and mobile app instead of three.

TECH STACK
Frontend: React, Next.js, Vue, TypeScript, JavaScript, HTML, CSS, Tailwind
Backend: Node.js (Express, NestJS), Laravel, PHP, Inertia, REST APIs
Mobile: React Native, Expo - one codebase for iOS and Android
Databases: MySQL, PostgreSQL, MongoDB, Supabase, Firebase
Automation & CRM: Go High Level, n8n, Zapier, Make
CMS & E-commerce: WordPress, Shopify
Tools: Git, Docker, Vercel

WHAT I CAN OWN
- Web platforms end to end - client app plus the admin dashboard behind it
- Cross-platform mobile apps in React Native
- REST APIs, backend services, and payment/auth/email integrations
- CRM workflows and automation pipelines in Go High Level, n8n, and Make
- Internal tools and dashboards that replace spreadsheet workflows
- Taking over existing or undocumented codebases and shipping fixes without
demanding a rewrite
- Ongoing maintenance and feature work after launch

PORTFOLIO AND OPEN SOURCE
-----------
20+ projects delivered across web, mobile, and automation work.
- Claude Code Agent Suite - 5 AI coding agents, published as an installable plugin marketplace: -----------/itzmerai/my-agents
- Developer Workflow Skills - 9 installable code review and delivery skills:
-----------/itzmerai/my-agent-skills
Most paid client work is under NDA. Happy to walk through architecture on a call.

HOW I WORK
- Available for full-time hours, including overlap with US or AU business hours
- I keep the hours I commit to and I am reachable during them
- Short written update at the end of each day, so you never ask for status
- I follow the conventions already in your codebase
- I document what I build so the work does not depend on me
- AI tooling for boilerplate and tests; architecture and code review stay with me
- Looking for a long-term position, not short engagements

Message me with the role and what you need built or maintained. I will reply with how I would approach it and the closest thing I have built.

Hi, I’m Johnrie, a Senior Full Stack AI Engineer with more than six years of experience building SaaS and AI-powered products.

I work across the full development cycle, from planning APIs and data flows to building the backend, connecting the frontend, writing tests, debugging production issues, and preparing releases. My main technologies include Python, FastAPI, Node.js, TypeScript, React, Next.js, PostgreSQL, Redis, AWS, and Docker.

I’ve worked on voice AI, legal research, and conversational automation products. My experience includes RAG pipelines, LLM integrations, real-time workflows, document processing, background jobs, and internal administration tools.

I enjoy taking complicated requirements and turning them into practical features people can understand and use. I communicate clearly, take ownership of my work, and focus on delivering reliable solutions instead of simply completing assigned tasks.

I'm an AI-Augmented Full-Stack Software Engineer specializing in building scalable web applications, SaaS platforms, and custom business systems. I work with Python (FastAPI), PHP (Laravel), JavaScript, React, Next.js, Vue.js, and C#, along with MySQL, SQL Server, REST APIs, Git, and modern development tools.

I've developed solutions for a variety of clients and projects, from custom web applications and internal business systems to admin dashboards and SaaS products. I focus on building software that solves real business problems while remaining easy to maintain, extend, and scale.

I use AI-powered development tools to improve productivity, accelerate research, assist with debugging, generate test cases, and speed up development without compromising code quality. Every feature is reviewed, tested, and refined to ensure it meets both technical and business requirements.

I believe great software is more than just writing code. I follow modern development practices such as version control with Git, API-first development, containerized environments with Docker, automated testing, CI/CD pipelines, code reviews, and structured deployment workflows to build reliable, maintainable, and production-ready applications.

I’ve built and contributed to SaaS and business applications across different industries. One of my key projects is TimeOff Management, a multi-tenant SaaS platform that I owned end-to-end, from architecture and database design to UI/UX, authentication, integrations, and deployment. I’ve also worked on healthcare and business platforms such as TheHopeHouse and CareDocs.

On the Shopify side, I specialize in Shopify Online Store 2.0, Liquid, custom themes, reusable sections, metafields, AJAX carts, product features, landing pages, Shopify Markets, Klaviyo, and third-party integrations. I’ve worked on storefronts including Odd Pieces, Agent84, Blossomdale, Skivys, and NSA Swim.

I also use AI tools such as Claude Code, Cursor, and Open-AI Codex to speed up development, debugging, and testing while keeping engineering decisions and code quality under human review.

Hi, I'm XC.
Frontend-leaning full-stack engineer with 8+ years shipping production web apps, and I build with AI agents every day.

At BillEase, a Philippine fintech, I build customer-facing Vue/Nuxt + TypeScript flows for KYC, payments, and credit products:
- Replaced a third-party liveness verification vendor with an in-house detection pipeline
- Led the frontend build of a new Credit Line product
- Redesigned Account Recovery with bot protection and security telemetry
- Migrated the app to a Figma-driven design-token system (Tailwind)
- Maintain production Python / Django REST APIs

Before that: mobile-first UIs, technical SEO, and performance monitoring for Gamesys/Bally's (UK/US teams); Python work on a cloud data warehouse (-----------); and a remote classroom platform built end to end with Flask, PostgreSQL, and FastAPI.

How I work: Claude Code and Cursor daily, with MCP integrations for Figma and ClickUp. AI speeds up the repetitive parts; architecture, UX, and code review stay in my hands.
