Hire · Full-stack AI Engineer · PHILIPPINES
I'm Marck England — a Philippines-based software engineer building AI SaaS, RAG pipelines, workflow automation, and custom web platforms for founders and product teams worldwide.
Each of these is a real service I've delivered in production — not a resume keyword list.
RAG-grounded chatbots that answer with your business data, not generic LLM guesses.
Custom chatbots trained on your products, prices, policies, and FAQs. Deployed on WhatsApp, Messenger, Instagram, LINE, or your own site. Smart "auto-off" logic hands off to your team the moment a human replies.
Retrieval-Augmented Generation systems that ground LLMs in your actual knowledge base.
End-to-end RAG pipelines — document ingestion, chunking, embedding, vector search, and grounded generation. Production-tested on real customer support and fact-checking workloads.
Replace manual triage with self-running systems that never miss a step.
n8n workflows, Celery background tasks, scheduled jobs, and event-driven pipelines. Built a 4-workflow n8n system with LangChain agents that automated an RFQ intake, vendor reply classification, and fallback reporting loop.
Production Next.js apps with the App Router, TypeScript, and modern data patterns.
Next.js 15/16 with App Router, Server Components, Server Actions, and edge-ready architecture. Type-safe end-to-end with TypeScript strict mode, Prisma, tRPC or Zod-validated APIs.
Custom SaaS platforms and CRMs built around how your team actually works.
Sales CRMs with cold outreach automation, credit systems, virtual currency, voucher support, and fine-grained role-based access control. Built a full CRM at Control Flow Labs replacing manual approvals with one-click actions.
Cross-platform iOS + Android apps that share business logic with your web stack.
React Native apps with native share-sheet integration, push notifications via Firebase Cloud Messaging, on-device classification, and secure API access. Built the Philippine fact-checking mobile app.
Fixed scope, fixed timeline, fixed price. Best for well-defined builds like a landing page, chatbot integration, or a specific feature.
