Production-grade engineering, on a startup clock.
We architect, build, and ship the systems your company runs on. Senior engineers. Real code. First commit by week two.
The systems behind the numbers.
Every case below ships from a production codebase. No mockups. No theoretical wins.
Every system we build looks like this.
Five layers, observable end-to-end, deployed via Terraform. We hand you the diagram, the runbook, and the on-call playbook on day one.
- Next.js / React, SSR + edge caching
- Design system + component library
- CDN with stale-while-revalidate
- Optimistic UI for write-heavy flows
- REST or GraphQL · OpenAPI specs
- Auth, RBAC, token rotation
- Event bus for async workflows
- Idempotency keys on every write
- Postgres · Mongo · DynamoDB
- Redis cache + session store
- Elasticsearch for search workloads
- PITR backups · cross-region replicas
- Kubernetes or Lambda runtimes
- Terraform-everything, no clickops
- Blue / green deploys, instant rollback
- Multi-AZ, multi-region where it matters
- Grafana dashboards · Prometheus metrics
- Sentry errors · structured logs
- Audit logs for every privileged action
- On-call rotation + runbook handoff
The four things we ship better than anyone you'll talk to.
We don't sell hours. We ship systems. Pricing visible up front because confident shops show their pricing.
Custom Platforms
Production systems built from first principles. Architecture, code, infra, observability. We own the whole stack and hand it back fully documented.
Product Engineering
Zero-to-one product builds for funded startups. From spec to App Store / production deploy. Senior engineers, weekly demos, two-week sprints.
Cloud & Infrastructure
AWS, Azure, GCP. Migrations, multi-region rebuilds, cost-optimisation passes. Terraform-everything, Grafana dashboards, on-call playbooks shipped on day one.
Senior Engineering Pods
A dedicated 2–6 engineer pod embedded in your team for 3–12 months. Same Slack, same standups, same git history. Scale up or down with 30 days' notice.
From kickoff to production. No black boxes.
You see code by week two. Every project. No exceptions.
Architecture Audit
Free 30-min call. 1-page written review in 48 hours. Honest go / no-go on fit.
Discovery & SOW
Stakeholder interviews + technical spike. Fixed-scope SOW within 5 business days.
Build
First commit by end of week 2. Two-week sprints with Friday demos. Direct Slack.
Deploy & Operate
Zero-downtime cutover. Load + chaos tested. On-call rotation handed off. 30-day exit.

We talked to four agencies. TantraDev was the only one that asked about our compliance roadmap on the first call — not our budget. Three months later we shipped, on time and under PCI scope.
The boring stuff your security team will ask for.
All standard. None of it negotiated.
What founders ask before signing.
30 minutes. One audit. A roadmap before we hang up.
Bring a system, a spec, or a problem. We'll send you a 1-page written architecture review — what to build, what to skip, what it'll cost — in your inbox before the call ends.
