01
The codebase
A monorepo organised by intent. Apps, packages, infrastructure, tests, and documentation, laid out so any engineer can navigate it on day one.
Karya · Software Development
Systems that
matter.
Built with clarity. Deployed with confidence. Owned end to end. Karya engineers software the way it should be engineered: architecture you can read, deployments you can trust, observability that tells the truth. We build for ten years, not ten weeks.
02 · How We Build
Disciplined by default.
Five architectural principles. Six categories of tests. Four operational stages from build to operate. Karya treats software engineering as a discipline with rules, not a vibes-based pursuit. The code becomes the contract.
01
Modular
Composable units with clean boundaries. Replace a part without rewriting the whole.
02
Observable
Every behaviour traced, every error logged, every metric named. Failure becomes investigable, not mysterious.
03
Testable
Code shaped so tests can prove correctness, not just demonstrate it on a good day.
04
Secure by default
Authn, authz, secrets and encryption present from the first commit. Not bolted on at audit time.
05
Owned end-to-end
One team owns the architecture, the code, the deployment, and the production behaviour. No handoffs at the seams.
03 · What We Build
Eight kinds of software.
From customer-facing web apps to internal admin portals, from AI systems that decide to deployment pipelines that ship: eight categories of software we build to the same standard. Modular, observable, testable, owned.
01
Web Apps
Fast, secure, and responsive web applications tailored to your workflows.
02
SaaS Platforms
Scalable, multi-tenant platforms built for growth, performance, and uptime.
03
Internal Tools
Custom tools that streamline operations and give your teams leverage.
04
AI Systems
Intelligent systems that automate decisions and unlock new capabilities.
05
APIs & Databases
APIs and database architectures designed for reliability and scale.
06
Automation Dashboards
Real-time dashboards that turn data into clarity and action.
07
Admin Portals
Secure, intuitive portals that give you full control and visibility.
08
Deployment Pipelines
Automated CI/CD pipelines that ship faster with confidence.
04 · Our Process
Nine stages,
one discipline.
Discover, architect, prototype, build, integrate, test, deploy, monitor, improve. Every project Karya takes on runs through the same nine stages. No shortcuts, no skipped phases. The discipline is what scales beyond the prototype.
- 01
Discover
Align on problems worth solving.
- 02
Architect
Design systems that scale.
- 03
Prototype
Validate ideas early and fast.
- 04
Build
Write clean code. Ship with quality.
- 05
Integrate
Connect services. Ensure reliability.
- 06
Test
Automate. Validate. Ship with confidence.
- 07
Deploy
Release cleanly. Zero surprises.
- 08
Monitor
Observe in real-time. Detect and respond.
- 09
Improve
Learn, iterate, and evolve.
05 · The Handover
The codebase as craft.
A monorepo you can navigate. Architecture documents that explain the why. Decision logs with dates. Git history that reads like a story. The work doesn’t disappear into a vendor’s tooling. It lives in your repository, structured for the next engineer who joins.
02
The architecture
System diagrams, context diagrams, and per-component design notes. They explain how it fits together, not just what each part does.
03
The decisions
ADR log, date-stamped and accepted. Future teams understand the reasoning, not just the outcome.
04
The history
Clean git branches, semver releases, named hotfixes. The project’s evolution is reconstructable from the commit log.
06 · The Stack
Picked by intent, not by trend.
Nine layers, each chosen for what it does well, not what’s popular this quarter. Frontend that renders fast at the edge. Backend that stays modular. Database with integrity guarantees. Auth, storage, observability, security: every component locked in for a reason we can defend.
- Frontend
Next.js 14, React, TypeScript, Tailwind CSS, shadcn/ui
Server Components, ISR, and edge-first rendering.
- Backend
Node.js, NestJS, TypeScript
Modular services, clean architecture, and API-first by design.
- Database
PostgreSQL, Prisma ORM
ACID compliant, relational integrity, and high performance.
- AI Layer
OpenAI, LangChain, Vector DB
RAG pipelines, embeddings, and tool orchestration for intelligent features.
- Auth
Auth.js, JWT, RBAC
Secure authentication, role-based access, and session management.
- Storage
AWS S3, CloudFront, R2
Durable object storage, CDN delivery, and global asset optimization.
- Observability
OpenTelemetry, Prometheus, Grafana, Sentry
Metrics, tracing, logs, and alerts you can act on.
- Infrastructure
AWS, Terraform, Docker
IaC, microservices, containers, and CI/CD for reliable deployments.
- Security
WAF, Shield, KMS, Secrets Manager
Defense in depth, encryption everywhere, and least-privilege access.

From here,
we build.
A system that needs to scale. A prototype that needs to ship. A codebase that needs the discipline you’ve just read about. Thirty minutes. No deck. We’ll tell you whether Karya is the right team for the work.
