CARAMEL
Full Stack Developer & AI Automation Engineer
I architect, build, and ship production-grade software across the full stack—from AI-powered products and backend systems to durable workflows, integrations, and business automation. I use the right AI tools for the job to move faster without compromising engineering judgment, while retaining ownership of architecture, implementation, review, debugging, security, and production quality.

I'm Jonas Viray, a Full Stack Developer and AI Automation Engineer based in the Philippines.
I take ownership of software from architecture through production, working across interfaces, backend services, APIs, databases, integrations, durable workflows, infrastructure, and automation. I use AI-assisted development with Codex and Claude Code to accelerate research, implementation, debugging, refactoring, and review while keeping technical decisions and final validation hands-on.
My work is centered on reliable systems, clear boundaries, maintainable code, and automation that reduces operational overhead. I think beyond individual features to how data moves, services fail, workflows recover, and teams maintain the system after launch.
From React and Next.js interfaces to Node.js and Laravel services, Python and FastAPI backends, Temporal durable workflows, Supabase and PostgreSQL data layers, Docker deployments, and n8n automation, I build end-to-end systems designed to hold up in production.
Education
Bachelor of Science in Computer Science
Quezonian Educational College, Inc. (QECI) · Atimonan, Quezon, Philippines
Graduated July 2026
Production systems spanning backend workflow orchestration, AI-enabled products, operations platforms, integrations, client implementations, and full-stack delivery. Every project is included in this carousel.
AI is part of my engineering workflow, not a substitute for engineering judgment. I use coding agents, context engineering, orchestration, reusable skills, and connected tools to accelerate delivery while I retain ownership of architecture, review, debugging, and production quality.
01 / AI engineering
I use AI coding agents for feature implementation, refactoring, debugging, codebase analysis, and technical documentation. I define the architecture, constraints, and acceptance criteria, then review and correct the output before it ships.
Workflow systems spanning orchestration, API integration, data movement, deterministic branching, AI boundaries, batching, notifications, and operational handoffs. Every automation is included in this carousel.
My experience is shown as a complete chronological timeline, including both recent software roles and earlier technical work.

Key contributions
Reference
https://www.facebook.com/WhitehatPH2I design and deliver software systems, integrations, and automation from architecture through production, with the implementation shaped around the business process and technical constraints.
End-to-end web applications, SaaS products, internal platforms, client portals, and role-based dashboards, covering frontend architecture, authenticated APIs, data models, integrations, and background processing.
Examples
React · Next.js · TypeScript · Node.js · Laravel · MySQL · PostgreSQL
Backend services and workflow orchestration for systems that need reliable APIs, persisted state, scheduled or long-running execution, retries, recovery, and clear operational boundaries.
Examples
Python · FastAPI · Temporal · Node.js · Supabase · PostgreSQL · Docker · Fly.io
Conversion-focused business websites, landing pages and funnels built in GoHighLevel with custom HTML, CSS and JavaScript where the builder falls short.
Operational workflows that reduce repetitive work across reporting, onboarding, notifications, email, CRM updates, document processing, and data synchronization between business systems.
Examples
n8n · Make.com · Zapier · Google Sheets · Slack · Discord
AI assistants, agents, and voice systems connected to business data and workflows so they can retrieve context, produce structured outputs, qualify leads, handle conversations, and trigger controlled actions.
Reliable integrations across CRMs, communication systems, ad platforms, spreadsheets, payments, booking tools, and internal applications, with clear data flow, validation, and failure handling.
Examples
REST APIs · Webhooks · GoHighLevel · Facebook Graph API · Supabase
Production delivery across Vercel, Docker, domains, HTTPS, caching, environment configuration, CI workflows, and practical security controls, with reliability and maintainability in mind.
Examples
Vercel · Netlify · Docker · Redis / Upstash · Cloudflare
Technologies I use across product interfaces, backend services, data, AI systems, creative production, automation, integrations, and production delivery. The emphasis is on how the pieces work together, not on collecting tools.
The engineering concerns behind the stack: architecture, durable execution, data integrity, AI boundaries, integration reliability, security, observability, testing, and long-term maintainability.
Jonas Viray is a Full Stack Developer and AI Automation Engineer who designs and ships production web applications, backend services, durable workflows, AI-enabled systems, integrations, and business automation from architecture through deployment.
Yes. Jonas Carlo Viray is his full name; he goes by Jonas Viray and also works under the name Caramel. This site (jonasviray.com) and his LinkedIn, GitHub, and OnlineJobsPH profiles all belong to the same person: a Full Stack Developer and AI Automation Engineer based in the Philippines.

I can work across the product surface and the systems behind it: React or Next.js interfaces, backend APIs, databases, authentication, integrations, workflow orchestration, AI features, deployment, and production troubleshooting. Recent examples include the Cynergists AI agentic CRM, business dashboards, booking and operations platforms, funding workflows, AI-connected applications, and Python/FastAPI backend services.
Yes. My backend work includes Node.js, Express, Nest.js, Laravel, Python, FastAPI, Supabase, PostgreSQL, Redis, and Temporal. I can extend an existing codebase, add APIs or integrations, stabilize production behavior, or build a new service around clearly defined system boundaries.
I use Codex and Claude Code as supervised engineering tools for codebase analysis, implementation, debugging, refactoring, testing, documentation, and review. AI speeds up execution, but architecture, constraints, security decisions, validation, and production responsibility stay under my control.
Yes. I regularly integrate existing systems rather than replacing them unnecessarily. My work includes GoHighLevel, n8n, Make, Zapier, Supabase, Firebase, Google Workspace, Slack, Discord, Stripe, Plaid, Twilio, ad APIs, REST APIs, webhooks, and custom backend services.
I'm based in Plaridel, Quezon, Philippines and work remotely on US Eastern Time (EST/EDT) business hours. My portfolio includes work with clients and teams in the United States and Australia, and I am comfortable collaborating asynchronously across product, operations, and technical stakeholders.
Start with the current system, the problem, the users affected, the constraints, and the outcome you need. I use that context to identify the likely architecture, integration points, risks, and implementation path before proposing scope or delivery stages.
For a role, existing codebase, or system problem, send the current stack, what needs to change, the constraints, and the target outcome. I can work from that context into an implementation plan, production fix, or working system.
