Full-stack engineering for teams who need to ship, not just plan.
JMFCool is Jeremiah Faria's development practice with 20+ years building web, mobile, and cloud products. One senior engineer, from architecture to production, no hand-offs.
Years shipping production web, mobile, and cloud applications.
Architecture, UI systems, APIs, databases, and deployment end to end.
You work directly with the engineer building your project. No account managers.
What I take on
Scoped engagements or ongoing support. Pick a lane or combine a few. Most projects run on the same stack I use for my own products, so it's already battle-tested.
Product & UI engineering
React, Next.js, TypeScript, and Tailwind responsive, accessible interfaces built to a real design system.
Full-stack & APIs
Node, serverless functions, REST routing, authentication, and data modeling with Postgres or Turso/libsql.
Deployment & DevOps
Vercel pipelines, GitHub Actions, environment management, and cache strategy that survives real traffic.
Database architecture
Schema design, migrations, and query optimization for Turso, libsql, Postgres, and Supabase.
Media & video pipelines
ffmpeg, H.264 encoding, and compression workflows for sites that need to move media at scale.
Dashboards & internal tools
Multi-tenant admin panels, client portals, and data-dense interfaces built for daily use.
A senior engineer, not a hand-off chain
Most agencies route your project through juniors after the sales call. Here, the person who scopes the work is the person who ships it.
No hand-offs
One senior engineer owns architecture, build, and deployment start to finish.
Ships fast, without cutting corners
Production-ready code from day one, not a prototype that needs a rebuild later.
Fits your existing stack
Works comfortably inside Vercel, GitHub, and Cloudflare setups your team already runs.
Clear, async-friendly communication
Written updates, real timelines, and no surprises on scope or budget.
Recently shipped
A sample of what's gone to production. The full portfolio and technical history live on the resume site.
Profile system & auth
Full-stack profile experience with authentication and a cleaner account-facing flow.
Stock market dashboard
Market-focused dashboard with visual summaries, watchlists, and decision-oriented layout.
Banners dashboard
Banner delivery system for affiliate, display, and email marketing partners.

Project details
How a project starts
Straightforward, four steps, no procurement maze. Every project starts with understanding the problem and ends with a production-ready result.
Discovery call
30 minutes to understand the goal, constraints, and timeline.
Scope & estimate
A clear proposal with deliverables, timeline, and cost, in writing.
Build & ship
Iterative builds with regular check-ins, deployed straight to production.
Support & iterate
Post-launch fixes, monitoring, and follow-on feature work as you grow.
