Dorico Dynamics LDA · Maputo, Mozambique

Engineering critical systems for finance, compliance, data, and workforce operations.

We build auditable software products and deliver cloud, migration, and engineering services for organisations operating under real constraints.

How we build

Engineering characteristics our repositories demonstrate

Each item below describes an implementation choice visible in the codebase. None of them is a certification, a guarantee, or a service level.

Go and Rust services, TypeScript interfaces

Production-oriented Go and Rust services behind Next.js and React operational interfaces.

Tenant-aware PostgreSQL domains

PostgreSQL-backed tenant and financial domains, with Redis used for bounded coordination and caching.

Contract-first APIs

REST and OpenAPI, protobuf, and gRPC/Connect contracts define service boundaries before code.

GitOps delivery

Kubernetes, Helm, Argo CD, structured CI gates, and rollback assets across multiple repositories.

Observability by default

OpenTelemetry instrumentation with structured request and correlation identifiers.

Deterministic where it matters

Compliance, accounting, planning, and migration logic is rule-driven and explainable rather than model-driven.

Products

Five products, built around auditability

Products explain what we build. Services explain how we work with clients. The two are kept separate on purpose.

Portfolio structure: Dorico Dynamics

Products

  • InfraNotes
  • Attesta
  • InfraShift
  • VoltaHR
  • HoyoAI

InfraNotes and Attesta share selected trust integrations: ledger controls, reporting, and document integrity. No other integration line is drawn, because shared technology is not integration.

Services

  • DevOps & Cloud
  • Cloud Migration
  • Custom Software Development
  • Technical Consulting

  • InfraNotes

    Financial operations, planning, and accounting

    Available by assessment · staged delivery

    Bring spend, budgets, vendors, projects, payroll, assets, grants, accounting, reconciliation, and reporting capabilities into a common tenant-aware platform, delivered in approved stages.

    Explore InfraNotes

  • Attesta

    Deterministic compliance and auditable evidence

    Controlled rollout

    Evaluate versioned rules, submit, organise, and review evidence, issue signed attestations, track remediation, and monitor drift through an auditable compliance workflow.

    Explore Attesta

  • InfraShift

    Controlled database migration and verified full backups

    Controlled pilot

    Plan, execute, resume, and validate database migrations; create encrypted full backups; and rehearse full restores into a new or empty same-engine database across PostgreSQL, MySQL, SQL Server, and MongoDB.

  • VoltaHR

    Workforce operations with tamper-evident governance in preview

    Core available · selected capabilities in preview

    Bring people operations, time, leave, payroll workflows, recruiting, and preview-stage tamper-evident overtime governance into one multi-tenant platform.

    Explore VoltaHR

  • HoyoAI

    Governed AI for software delivery and GitOps

    Controlled availability

    Review exact code revisions, apply repository policy, produce auditable findings, and build toward controlled GitOps change workflows without surrendering human approval.

    Explore HoyoAI

Availability labels describe how each product is delivered today. They are not general-availability or production-readiness statements.

How the systems are built

Principles that recur across the portfolio

These are recurring design decisions, not blanket guarantees. Where a boundary applies to specific workflows only, the product page says so.

Abstract view of a tenant-aware platform: a compliance gate, durable state, and an append-only evidence chain joined by explicit contracts. Illustrative — it does not depict a specific deployment.

Deterministic controls

Explicit rules, versioned mappings, and reproducible evaluation, so a decision can be explained and re-run rather than trusted.

Tenant isolation

Explicit tenant, role, scope, and entitlement boundaries, including forced PostgreSQL row-level security in the VoltaHR workforce core.

Contract-first integration

OpenAPI, protobuf, gRPC and Connect contracts, event schemas, and gateway-level domain ownership instead of one undifferentiated backend.

Audit evidence

Append-only logs, immutable document versions, hash chains, evidence packs, and reproducible evaluations recur across products.

Observability and delivery

Probes, telemetry, structured logs, rate limits, circuit breakers, CI gates, and documented rollback paths.

Operator-owned change

Consequential change stays with a human. InfraShift cutovers and HoyoAI delivery boundaries both require operator go/no-go, and selected Attesta and ledger paths fail closed.

Services

How we work with clients

Four engagement families, scoped around demonstrated engineering work.

  • DevOps & Cloud

    Delivery platforms built for repeatable change.

    Container platforms, GitOps delivery, observability, release controls, and operational safeguards.

    Learn more

  • Cloud Migration

    Migrations planned around evidence, reversibility, and cutover control.

    Dependency assessment, staged migration paths, validated outcomes, and operator-owned go/no-go.

    Learn more

  • Custom Software Development

    Domain software engineered for operational depth.

    Tenant-aware platforms and backend services with explicit contracts, durable workflows, and auditability.

    Learn more

  • Technical Consulting

    Architecture and delivery decisions grounded in implementation.

    Architecture review, delivery risk, regulated workflows, data migration, and modernisation choices.

Workflow stories

What the systems actually do

Designed workflow models drawn from the architecture documents. Where an end-to-end environment test has not been supplied, we describe them as designed rather than proven.

  1. InfraNotes

    Expense to budget to ledger

    An approved expense consumes budget, posts to the general ledger, and feeds reconciliation and reporting through tenant-aware services rather than a single backend.

  2. Attesta

    Rule to evidence to attestation

    A versioned rulepack evaluates submitted evidence deterministically, produces a reproducible result, and issues a signed attestation with chain verification.

  3. InfraShift

    Analyse, rehearse, validate, cut over

    Derive a dependency-aware plan, copy schema and data with bounded concurrency and resumable checkpoints, validate counts and constraints, then hand cutover to an operator.

  4. VoltaHR

    Preauthorised overtime to tamper-evident record

    Overtime is preauthorised, linked to attendance, reviewed bilaterally, and written to an append-only hash-chained event log with daily Merkle roots.

Scoped facts

Numbers we can source

Each figure below names its own boundary. We do not publish latency, throughput, uptime, or adoption figures, because no current evidence supports them as product claims.

Trust and delivery

How we describe our own work

Every claim carries its scope

Capability statements name the product, environment, and workflow they apply to. A deployment manifest is not evidence of live traffic.

We publish limitations

Each product page lists what is not implemented, disabled, or unverified. A clear boundary is more useful than an absolute.

Humans own consequential change

Cutovers, merges, deployments, and approvals stay with named operators in the workflows where we say so.

Tell us what you are trying to build or migrate.

We respond with a scoped technical view of the work, the constraints we see, and what we would need to verify first.
