Available for contract work

I build reliable software
for products that move money and people.

I'm Marco, a senior full-stack and distributed systems engineer with 10+ years shipping at Netflix, PayPal and fast-moving startups. I help teams launch features, harden payments and auth, and make front ends fast.

Performance & scale

Faster pages, leaner APIs and distributed systems that hold up when traffic spikes.
