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Documentation Confluence pages, often outdated README at best ADRs, API docs, runbooks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.

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.

1

Discovery

Free 30–60 min call. We understand your domain, constraints, and success criteria.

2

Architecture

SDD-driven architecture design. Domain model, service boundaries, API contracts, ADRs.

3

Development

AI-accelerated implementation. Daily progress visible in Git commits and CI/CD runs.

4

Testing

Comprehensive automated testing. Integration, unit, and contract tests with real databases.

5

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.
