WHY NOSOTA
Not a Large Agency. Better Than One.
Large agencies add layers of management. Freelancers lack enterprise methodology. NOSOTA combines senior-level architecture with AI-accelerated execution — one engineer delivering what agencies staff teams for.
| Large Agency | Freelancer | NOSOTA | |
|---|---|---|---|
| Architecture | Generic, varies by team | Ad-hoc, undocumented | SDD methodology, domain-driven |
| Test coverage | 40–60% typical | Minimal or none | 319 tests, integration + unit |
| CI/CD | DevOps team required | Manual deploys | 12 pipelines, automated |
| Documentation | Confluence pages, often outdated | README at best | ADRs, API docs, runbooks |
| Team size | 5–8 people, coordination overhead | 1 person, single point of failure | 1 engineer + 7 AI roles |
| Communication | Via project manager | Direct but unstructured | Direct with the engineer |
| Delivery speed | 3–6 months | Unpredictable | 12 days (proven) |
| Cost structure | High fixed + change orders | Low hourly, scope creep | Transparent, 3 models |
| Code ownership | Often retained by agency | Yours, but hard to maintain | 100% yours, documented |
| Long-term support | Retainer contracts | No guarantees | Dedicated engineer option |
Every claim above is backed by the Grain Warehouse Registry case — 13 microservices, 55K lines, 12 days.
WHAT WE BUILD
Enterprise Systems We Deliver
Distributed Microservices
Event-driven architectures with domain-bounded services, async messaging, and independent deployment. Spring Boot, Kafka, PostgreSQL.
Multi-Role Portals
Role-based access control, multi-tenant data isolation, admin dashboards, and operator portals with complex business workflows.
Regulatory Compliance
Audit trails, data retention policies, GDPR/SOX/PCI-DSS compliance layers integrated into the architecture from day one.
API-First Backends
RESTful and GraphQL APIs with OpenAPI specs, versioning, rate limiting, and comprehensive integration test suites.
AI-Integrated Systems
LLM-powered features, document processing, intelligent search, and decision support integrated into enterprise workflows.
Legacy Modernisation
Strangler fig pattern migration from monolith to microservices, database decomposition, and zero-downtime cutover strategies.
OUR APPROACH
Enterprise Architecture, AI-Accelerated
The SDD method ensures enterprise systems are architected before code is written. AI accelerates execution, not shortcuts.
Architecture First
- Domain model and bounded contexts first
- API contracts defined before implementation
- Architecture Decision Records for every choice
- Infrastructure as Code from the start
Quality Built In
- Unit + integration + contract tests
- Testcontainers for real database testing
- 319+ automated tests per system
- CI gates: no merge without green build
Production Ready
- Kubernetes manifests and Helm charts
- 12 CI/CD pipelines per system
- Health checks, logging, monitoring
- Zero-downtime deployment strategy

ENGAGEMENT
How We Work on Enterprise Projects
Every enterprise project follows a proven 5-phase process, regardless of engagement model.
Discovery
Free 30–60 min call. We understand your domain, constraints, and success criteria.
Architecture
SDD-driven architecture design. Domain model, service boundaries, API contracts, ADRs.
Development
AI-accelerated implementation. Daily progress visible in Git commits and CI/CD runs.
Testing
Comprehensive automated testing. Integration, unit, and contract tests with real databases.
Deployment
Kubernetes deployment with Helm charts, monitoring, and zero-downtime rollout.
Fixed-Cost
Scoped specification → fixed price → no surprises. Best for well-defined enterprise projects.
Time & Material
Weekly billing against delivered work. Best for evolving requirements or R&D phases.
Dedicated Engineer
Full-time senior engineer on your project. Best for continuous development and team extension.
FAQ
Enterprise Development Questions
Can one engineer really deliver an enterprise system?
Yes — and we’ve proven it. The Grain Warehouse Registry: 13 microservices, 55K lines of production code, 319 automated tests, 12 CI/CD pipelines — delivered by one senior engineer in 12 days. The SDD method orchestrates 7 AI roles under one engineer’s direction. This isn’t a shortcut — it’s a force multiplier.
How do you ensure production-grade quality?
Three layers: (1) Architecture-first design with SDD methodology ensures correct structure before code. (2) 319+ automated tests including integration tests with Testcontainers against real databases. (3) 12 CI/CD pipelines with gates — no merge without a green build. Every number is traceable to a Git commit.
What happens after launch — do you provide support?
Yes. We offer three post-launch options: (1) Dedicated Engineer model for continuous development. (2) Time & Material support for periodic updates. (3) Knowledge transfer with complete documentation — ADRs, API docs, runbooks — so any qualified team can maintain the system.
How does pricing work for enterprise projects?
Three models: Fixed-Cost for scoped projects (price set before development), Time & Material for evolving requirements (billed against delivered work), and Dedicated Engineer for continuous development (monthly retainer). Discovery call is free and NDA-protected.
Can you integrate with our existing systems?
Absolutely. API-first architecture means every service exposes documented, versioned endpoints. We’ve integrated with national commodity exchanges, payment systems, and third-party regulatory platforms. Integration requirements are mapped during the Architecture phase.
