Production infrastructure
that earns its uptime.
TantraDev designs, builds, and operates the systems your engineers will rely on for the next decade — engineered for sustained load, observable by default, and recoverable without us.
We don’t ship demos. We ship runtimes.
Every system we leave with you is something we’d put our names on the on-call rotation for. That changes the choices: Terraform from day one, runbooks before the first deploy, observability built into the data model, and an exit clause on every contract — because the day you don’t need us, the runbook works without us.
Five production-grade systems. One operating posture.
Each carries the same engineering commitments. The differences are in what we instrument, not how we operate it.
Custom platforms, edge to disk
The full stack written from first principles. Architecture, code, infra, observability — all of it, ours to build, yours to keep. Documented like we expect to be audited.
Cloud infrastructure & SRE
AWS, Azure, GCP — or the migration between them. Multi-region rebuilds, cost-optimisation passes, latency post-mortems. Terraform for everything, Grafana for the boring parts, a runbook for the 3 AM call you hope never comes.
AI & data engineering
The pipelines, vector stores, feature platforms, and inference paths that turn an ML idea into something a model can actually serve under load. Cost modelled, latency budgeted, evaluated continuously.
Real-time + event-driven systems
Streaming ingest, idempotent processing, replayable event stores. Kafka-compat, gRPC, WebSocket fan-out. The systems that don't tolerate retry-and-hope.
Senior engineering pods
A 2–6 engineer pod, embedded — not “augmented.” Same Slack, same standups, same git history. Three to twelve months, scale up or down with 30 days' notice, no offshore handoff.
What’s true on every system we ship.
Six commitments that don’t change with the SOW.
Observable by default.
OpenTelemetry traces, structured logs, RED + USE dashboards in Grafana, alerts wired to your PagerDuty before the cutover.
Deployment-safe architectures.
Blue-green or canary, never a flip. Database migrations are reversible. Feature flags ship with the feature.
Engineered for failure recovery.
RTO and RPO written into the design. Backups verified by restore drill. Postmortem template ships with the runbook.
Latency-optimized across regions.
p99 budgeted at design time. Edge caching, regional read replicas, async where async is honest.
Auditable end-to-end.
Every privileged action logged immutably. Audit logs queryable from day one, exportable to your SIEM.
Built to be handed off.
30-day exit on every contract. Knowledge-transfer sessions. Infrastructure-as-code, runbook, on-call playbook — yours, not ours.
Built for the way your industry runs.
Compliance and constraint are not adversities. They are architecture inputs. Here’s how that shapes what we ship per vertical.
PCI scope is an architecture decision, not a paperwork decision. We treat it that way from day one.
Payment platforms, settlement engines, fraud-screening pipelines, multi-currency cores. PCI DSS scope reduced from 'whole platform' to 'two services in one VPC' via tokenisation vaults. Audit-ready by week four, not week forty.
- Tokenisation vault in isolated VPC
- Idempotent settlement with replay
- Partitioned Postgres per currency
- Real-time fraud scoring at the edge
- Immutable audit log to your SIEM
Numbers from the systems we operate.
Measured from production. Updated monthly.
The stack we deploy.
Click any layer for the tools we pick and why. The “we work in your stack, we don’t religion it” clause is real.
- OpenTelemetry
- Grafana
- Loki
- Tempo
- PagerDuty
Every system we ship is observable by default — RED + USE dashboards in Grafana, traces correlated by request ID, alerts wired to your PagerDuty before the cutover.
One trace ID from edge to disk. Alerts before customers notice.
- PostgreSQL
- Redis
- Kafka
- S3
- Snowflake
Postgres for transactional. Redis for ephemeral. Kafka for streams. S3 for blobs. Snowflake when the data team asks. We pick the proven thing 90% of the time so we can pick the right thing the other 10%.
Boring is a feature. Boring is what stays up at 4 AM.
- Node.js
- Go
- Python
- Rust
Node for API-shaped work. Go for high-throughput services. Python where the ML team already lives. Rust when latency demands the metal.
Language follows workload, not preference.
- tRPC
- GraphQL
- gRPC
- OpenAPI
Type-safe between server and client (tRPC). Federation across services (GraphQL). High-performance internal (gRPC). External-facing contracts (OpenAPI). We pick per use case, not per ideology.
One contract per layer. Versioned. Documented at code-time.
- Cloudflare
- Vercel
- AWS CloudFront
Edge caching for static and stale-while-revalidate. Edge compute for personalisation and routing decisions. Origin only when origin is the truth.
Cache what you can. Compute what you must.
Six commitments. Same every project.
Operational first
The day we walk away, your team is the one paging on it. Every choice we make is the choice that team would have made.
Boring where it counts
PostgreSQL, Redis, Kafka, S3. We pick the proven thing 90% of the time so we can pick the right thing the other 10%.
Documented like we're audited
Every system ships with architecture diagrams, runbooks, on-call playbooks. Documentation is a deliverable, not a courtesy.
Observable or it doesn't exist
You can't operate what you can't see. Telemetry is in the data model from week one, not bolted on after launch.
Tested in production
We don't just unit-test. We chaos-test, load-test, and shadow-test in production traffic before the cutover.
Exitable by design
30-day exit clause on every contract. Infrastructure-as-code from day one. The runbook works without us.
Kickoff to production in four phases. No black boxes.
A real engineer is in your repo by week two on every project — with a fixed deliverable for each phase, written and signed.
Architecture Audit
One call. One page. 48 hours — including the “we’re not the right fit” version.
Discovery & SOW
Five business days from yes to signed SOW. Fixed scope, not an estimate with twelve assumptions.
Build
First commit, week 2. Friday demos on real code. The engineer who scoped ships.
Deploy & Operate
Zero-downtime cutover. Load + chaos tested. 30-day exit — the runbook works without us.

What engineers ask. Not what the brochure answers.
30 minutes on the phone. One page in your inbox. A roadmap before we hang up.
Bring a system, a spec, or a problem. We’ll send you a one-page written architecture review — what to build, what to skip, what it’ll cost — before the call ends. You keep the audit even if we’re not the right fit.
