About this gig

Struggling to scale? Your architecture is probably the reason.

Most startups hit a wall not because of bad code, but because the system wasn't built to grow. Slow queries, ballooning cloud bills, and downtime under load all trace back to architectural decisions made too early or too late.

I design system architectures that scale cleanly from your first users to your first millionwithout over-engineering or overspending.

What I deliver:

  • Architecture diagrams (C4, sequence, deployment)
  • Tech stack recommendations for your budget and team
  • Database design & data flow (SQL/NoSQL, caching, sharding)
  • Scalability plan: load balancing, autoscaling, microservices vs. monolith
  • Cloud design (AWS, GCP, or Azure)
  • Cost estimation & optimization
  • Security & reliability best practices

Who it's for:

Founders, CTOs, and teams building or scaling a product.
