Questions, answered
One design is a complete architecture report — a system story, requirements brief, design decisions, every component on the critical path, a traffic envelope, three labelled diagrams, monthly cost ranges in INR, risks, guardrails, observability notes, and a phased roadmap.
You also get a downloadable PDF and a permanent versioned record you can re-open, share, or compare against later iterations.
For teams
Workshop a portfolio of designs, give every founder on your team a seat, or run cost comparisons across architectures. We'll set up a shared wallet, custom invoicing, and a dedicated point of contact.
