Problems We Solve

When engineering problems block product growth

Software platforms often reach a stage where early technical decisions begin limiting product evolution. Naubly typically works with teams facing challenges such as:

Architecture that cannot scale

Early system decisions begin creating technical debt that blocks new features and increases maintenance cost.

Backend platforms becoming slow or unreliable

APIs degrade under load, infrastructure becomes unpredictable, and reliability issues start affecting users.

Engineering velocity dropping

Teams spend more time working around infrastructure problems than shipping product features.

Complex integrations creating fragile systems

Payment providers, analytics platforms, and third-party APIs must operate reliably together under real conditions.

MVP platforms needing production-grade architecture

Systems built quickly must evolve into stable, maintainable platforms that internal teams can extend.

Engineering Principles

How Naubly approaches engineering systems

Reliable software platforms require disciplined engineering practices.

Architecture before implementation

Systems are designed before development begins to avoid costly refactoring later.

Clear system boundaries

Services, APIs, and data models are defined with explicit contracts between components.

Performance as a design constraint

Performance considerations are incorporated early in system design, not bolted on after the fact.

Maintainable systems

Codebases are structured so internal teams can extend and maintain them long after delivery.

Services

The right engineering help for the problem in front of you.

Focused support for teams that need better foundations, more reliable systems, or experienced delivery capacity.

Indicative starting points in USD. Final scope, deliverables, and responsibilities are agreed before work begins.

Flagship offer

Workflow & Integration Engineering

Starting at US$2,500

Connect systems, automate business processes, and build dependable workflows with clear implementation scope.

Best suited to: Founders and product teams replacing manual handoffs, integrating external APIs, or orchestrating critical business workflows.

—System and API integrations
—Backend orchestration and data flows
—Testing, observability, and documented handoff

Why it matters: Reliable workflows reduce operational friction while giving your team a clearer path from business need to working software.

Backend Reliability & Remediation

From US$400 for narrowly bounded tasks

Investigate and resolve a defined bottleneck, failure mode, or operational gap in an existing application.

Best suited to: Teams that need evidence-led remediation without treating a narrowly scoped task as a full platform engagement.

—Performance or failure-mode investigation
—Critical-path fixes and targeted tests
—Concise findings and implementation handoff

Why it matters: Start with a contained problem, improve what matters most, and leave the system easier to operate with confidence.

Discuss your project

Product & Platform Engineering

Starting at US$4,000

Build or modernize the software foundations and product capabilities needed for the next stage of growth.

Best suited to: Product teams extending a platform, replacing fragile foundations, or delivering a larger feature with defined scope.

—Backend APIs and application architecture
—Database and data-model design
—Implementation, testing, and maintainable delivery

Why it matters: Clear boundaries and reliable foundations make future product work easier to ship and safer to change.

Ongoing partnership

Naubly Ongoing Engineering Partnership

US$1,000 per month

A flexible engineering relationship for businesses with a recurring stream of smaller maintenance, integration, and improvement priorities.

What is included

Up to 8 engineering hours per month for implementation, investigation, testing, and directly related work.
Monthly prioritization around the highest-value eligible work.
Acknowledgment of requests within two business days.
Lightweight updates on completed work, risks, and next steps where useful.

Boundaries that protect delivery

Unused capacity does not roll over, and work beyond eight hours needs explicit agreement.
No 24/7 coverage, emergency on-call service, or guaranteed incident resolution.
Major features, migrations, and larger integrations are separately scoped.
Third-party costs and access-dependent work remain outside the monthly fee.

Choose a fixed-scope project when the outcome is defined. Choose the partnership when priorities recur month to month and continuity is more useful than a single delivery plan. The engagement is subject to scope, capacity, feasibility, access, and agreed priorities.

Selected work

Evidence of engineering work that holds up under real constraints.

A few documented examples across critical integrations, backend architecture, and reusable product tooling.

Documented experience · critical integrations

Payment migration under deadline

View supporting profile

Planning a payment migration without losing sight of continuity

Context. A payment integration had to change while active billing cycles continued and subscriber continuity could not be treated as an afterthought.

Approach and result. The documented experience centers on subscriber state, edge cases, and sequencing a processor change around the risk of service interruption. The public profile does not expose enough implementation detail to claim a complete client case study, so this example is presented as relevant engineering experience rather than a guaranteed outcome.

Why it matters. For teams changing a critical integration, careful sequencing and correctness matter as much as implementation speed.

Independent engineering project · protocol and runtime

Signal

Read the Signal case study Explore Signal

Engineering backend correctness

Context. Signal is a reusable decision-processing platform for events, evidence, assessment, decisions, learning, memory, replay, and audit.

Approach and result. The public repository documents protocol-governed operation contracts, runtime dispatch, idempotency and replay metadata, subscriber dedupe, audit evidence, and a runnable reference proof. The case study distinguishes documented behavior from guarantees that require deeper inspection.

Why it matters. For teams operating critical state changes, explicit contracts and inspectable evidence create a stronger starting point for correctness discussions.

Open source · reusable engineering

Reusable conversion tooling

View repository

HTML to editable Gutenberg blocks

Context. WordPress workflows often involve repetitive conversion work that is difficult to reuse and easy to get wrong by hand.

Approach and result. html-to-gutenberg converts arbitrary HTML into fully editable WordPress Gutenberg blocks and provides a preview of the result. The public package also supports modern output workflows and test coverage.

Why it matters. Reusable tooling can remove repetitive work from a delivery process and give teams a more dependable path from source content to editable output.

How collaboration works

A focused path from uncertainty to working software.

Align on the objective

Clarify the product goal, constraints, current system, and what a useful outcome looks like.

Define the approach

Choose the smallest sound path forward, with clear boundaries, trade-offs, and milestones.

Engineer and validate

Build the work, test critical paths, and keep progress visible as decisions become implementation.

Deliver and iterate

Ship working software, document what matters, and continue improving where the product needs it.

Engagement model

Project delivery when scope is clear. Ongoing partnership when the work continues.

Choose a fixed-scope project when the outcome and deliverables are clear. Choose the ongoing partnership when smaller engineering priorities recur month to month. If the work exceeds the monthly capacity or needs a dedicated delivery plan, Naubly can scope it separately—without implying that the partnership includes a larger project.
