Full-Stack Developer | Custom CRM n8n Automation | Next.js
Metro Manila
Full-stack developer who builds business automation, either in custom code or in n8n, and custom CRMs built around how a business actually operates, instead of forcing it into an off-the-shelf tool. What I build: - Custom CRMs: pipelines, contact and account records, lead tracking, role-based access, and reporting, built on Next.js, TypeScript, and Supabase (Postgres) to fit your process. - Automation: workflows in n8n when speed matters, and custom code (APIs, queues, Redis-backed jobs) when a no-code tool hits its limits. I pick the approach that's cheaper to maintain for your case. - AI-assisted workflows: LLM and MCP integrations that handle repetitive reporting, data pulling, and follow-up work. - Analytics and tracking: GA4 and Google Tag Manager across ~95 client accounts, so lead and conversion data reaches your CRM and reports accurately. Production experience: I build and maintain two internal platforms at a digital marketing agency, an SEO operations platform and a PPC reporting portal, covering APIs, authentication, database design, dashboards, and Vercel deployments. What sets me apart: most automation freelancers can connect apps but can't build the missing piece, and most developers don't understand lead and marketing data. I handle the full path from workflow design to the code behind it to ongoing maintenance, so you deal with one person instead of coordinating several. Background: BS Computer Engineering (FEU Institute of Technology), Elite Scholar and Dean's Lister. Prior freelance web development experience. Good fit for: custom CRM builds, lead-to-sales automation, internal tools, reporting dashboards, and SaaS MVPs. Portfolio: daryl-guerzon.vercel.app
