Acerca de Marc
Build high-performance web apps or automate the bottlenecks slowing you down? I provide the engineering to do both.
I am a Junior Full Stack & Automation Engineer with a "product-first" mindset. I build the user-facing tools your business needs while engineering the "invisible" automation that keeps your operations running at 10x speed.
How I Help Your Business:
I help founders and CTOs bridge the gap between complex architecture and intelligent automation. Whether launching an MVP or integrating AI, I deliver clean code and robust workflows that solve real business pains.
My Dual Expertise (The 50/50 Split):
- Full Stack Engineering:
I build responsive, scalable web apps using React, Next.js, and TypeScript. On the backend, I develop reliable microservices with Node.js, Express, and PostgreSQL, managing CI/CD pipelines (GitHub Actions/AWS) for high stability.
- AI & Process Automation
I "hunt" for manual friction using n8n orchestration to connect your CRM, Slack, and internal tools. I deeply embed LLMs (Claude, Gemini) for data classification and autonomous workflows with minimal intervention.
What I Deliver:
End-to-End Internal Tools: Custom web apps that solve specific operational pains (e.g., my CapEx Reviewer Tool built for The Knot Worldwide).
Automated Data Pipelines: Seamless ingestion systems that sync data between third-party services and your core databases.
Scalable Frontends: High-performance SSR applications built with Tailwind CSS.
AI Agents: Intelligent workflows that leverage Prompt Engineering to automate technical and financial reviews.
The Difference:
I worked in international engineering teams at The Knot Worldwide where I learned how big companies are growing. I don't just "hack" things together; I build sustainable architecture that grows with your business.
