Software used to mean filing tickets, waiting on five teams, and hoping the design survives the handoff. Darsh Gupta is the only contractor who acts like a co-pilot for you (and your AI agents) — design, frontend, backend, infra — autonomously.
Frontend, backend, infra, design, payments, real-time, auth — no hand-offs. The seam where most projects die just isn’t there. Tap any number to open the receipt.
Not your mama’s freelancer. Design, frontend, backend, integrations and devops live as a first-class single workflow — meaning you can ship in days, not quarters.
Inheriting a broken Next.js / NestJS / Prisma stack? I’ve published six MIT libraries and shipped 24+ production systems. The bug is probably one I’ve already fixed.
// from a real audit - 4,020-line schema → 139 models, 255+ composite indexes - N+1 across 3 modules → batched in a single migration - Cron drift on 8 jobs → unified BullMQ + alerting - Sentry P95 638ms → 142ms after 1 week
Preview deploys per branch, type-safe end-to-end, real users behind feature gates, and a rollback that doesn’t require a war room.
