Technology

Applied AI, RAG, agents, and AWS—engineered as systems.

Our experience spans model integration, private retrieval, bounded agent workflows, evaluation controls, and cloud delivery. We state the deployment boundary and evidence level for the system in scope.

Architecture

Reusable patterns, composed for the problem.

We reuse versioned services, adapters, workflow controls, evaluation patterns, and deployment practices where they fit. Each system still gets its own data, authority, risk, and recovery boundary.

Shared components make proven work reusable; explicit boundaries prevent one product's assumptions from silently becoming another product's operating model. The result is a portfolio with common engineering discipline, not a claim that every application uses the same architecture or maturity level.

Platform anatomy

Shared foundation

L5Interface

Operator-facing dashboards and workspaces built for decisions, not reports.

L4Orchestration

Workflow logic, specialist-agent routing, durable jobs, approvals, and tool coordination.

L3Services & APIs

Versioned services with explicit boundaries and an integration layer.

L2Data & Intelligence

Model integration, governed retrieval, evaluation, document pipelines, and analytics.

L1Infrastructure

AWS and local deployment patterns with scoped identity, storage, observability, and recovery.

AI orchestration

AI is engineered, not bolted on.

Language, vision, and generative models are treated like any other part of the system — directed by explicit logic, checked against expected output, observable when something drifts.

01Input
02Direct
03Generate
04Validate
05Deliver

For scoped AI workflows, we define inputs, expected output shape, validation, retry limits, fallback behavior, and human escalation. These controls reduce silent failure; they do not guarantee that a model will always be correct. Acceptance tests are built from the real inputs and consequences of the engagement.

Applied AI experience

From models to controlled operating systems.

Our experience includes working implementations and tested local systems across retrieval, agents, tool use, and AI-response quality. The model, data boundary, and authority level are selected for each engagement.

Applied AI

AI and LLM application engineering

Structured model outputs, multimodal inputs, provider adapters, validation, retries, fallbacks, and reviewer queues around defined operational tasks.

  • LLM integration
  • Structured outputs
  • Vision & audio inputs
  • Provider adapters
  • Human review

Knowledge systems

RAG and source-aware retrieval

Governed ingestion, semantic chunking, hybrid vector and keyword retrieval, reranking, citations, metadata filters, and namespace isolation.

  • ChromaDB
  • PostgreSQL + pgvector
  • Ollama embeddings
  • Source citations
  • Access logs

Agent systems

Agents, tools, and orchestration

Specialist routing, durable task state, API and MCP-compatible tools, risk review, adversarial review, and approval gates for consequential side effects.

  • Multi-agent routing
  • MCP integrations
  • Tool allowlists
  • Approval queues
  • Audit trails

Quality controls

Evaluation, guardrails, and evidence

Regression fixtures and response contracts that separate facts, assumptions, unknowns, confidence, evidence, risks, counterarguments, and recommendations.

  • Regression evals
  • Claim checks
  • Red-team modes
  • Uncertainty
  • Release gates

These are engineering capabilities, not a promise that every model is accurate, every workflow is autonomous, or every deployment uses every component. We verify the selected pattern against the engagement's sources, tests, permissions, and failure modes.

AWS experience

Cloud architecture with operating evidence.

Our experience includes production static delivery and source-backed work across serverless, container, data, identity, document, observability, security, and cost-control services. Current use is verified for each engagement instead of implied from this inventory.

Web and edge delivery

S3 · CloudFront · Route 53 · ACM · WAF

Static delivery, origin access controls, certificates, DNS, cache policy, invalidation, and public artifact verification.

Compute and integration

Lambda · API Gateway · ECS/Fargate · App Runner · ALB · ECR

Serverless, container, and managed-compute patterns selected for the workload, operating model, and rollback needs.

Data and document systems

RDS/PostgreSQL · DynamoDB · S3 · Textract · Bedrock

Relational and document data paths, distributed rate controls, OCR pipelines, and constrained model integrations with review boundaries.

Security and operations

IAM · KMS · Secrets Manager · CloudWatch · CloudTrail · Config · Cost Explorer

Least-privilege roles, encryption and secrets boundaries, logging, inventory, cost analysis, workload guardrails, and recovery evidence.

The stack

A deliberate, modern technology base.

We choose proven, well-supported technologies and use them consistently across the portfolio.

  • TypeScript
  • React
  • Next.js
  • Electron
  • Tailwind CSS

Services & APIs

  • Python
  • FastAPI
  • REST & integration APIs
  • Workflow orchestration

Intelligence

  • LLM and multimodal model integration
  • RAG, embeddings, hybrid retrieval, and reranking
  • OCR and document extraction pipelines
  • AI evaluation, evidence checks, and red-team review

Infrastructure & operations

  • AWS static, serverless, container, and managed-compute patterns
  • PostgreSQL, pgvector-compatible designs, and object storage
  • Identity, secrets, encryption, WAF, and audit services
  • Observability, cost controls, deployment verification, and rollback
Security & operational design

Security is how the software is built.

It is a property of the architecture from the first commit — not a layer added before launch.

Least-privilege access

We scope identities, service roles, secrets, and data access to the deployment. Encryption and key-management requirements are documented for that boundary.

Explicit, auditable boundaries

System boundaries are deliberate and observable, so access and data flow can be reasoned about — not assumed.

Operational discretion

We do not publish deployment-specific configuration, credentials, or sensitive topology. Discretion about the inner workings is part of the design, not an omission.

We are glad to walk technical evaluators, partners, and reviewers through how the platforms are built.
