Solutions & Engagements

Engineering engagements built around the system — not a generic package.

From architecture reviews and focused engineering work to complete business-critical platforms, FireXCore scopes each engagement around the actual system, risk and delivery requirements.

Core capabilities

Software for operations that cannot be reduced to a landing page.

Four engineering areas cover the majority of FireXCore's current system work.

01
Business-critical software

Product & Systems Engineering

Backend systems, vertical SaaS and internal platforms designed around real business workflows, durable state and operational clarity.

Typical problems

  • A critical workflow still depends on spreadsheets, email or disconnected tools.
  • An existing application has reached its architectural or operational limits.
  • A new product needs a backend that can survive growth, retries and changing business rules.

Typical deliverables

  • System architecture and domain model
  • Backend APIs and business workflows
  • Role and permission boundaries
  • Integrations and migration paths
  • Testing, deployment and handover

Focused digital work remains available. Selected WordPress, web-performance and SEO engagements are scoped separately rather than presented as fixed engineering packages.
Engagement models

Choose the level of engineering responsibility — not a fake tier.

Starting prices provide planning context. A proposal is issued only after the scope and constraints are understood.

01

Technical Assessment

From $1,500 fixed-scope engagement

A bounded technical review used to understand the current system, define risks and turn uncertainty into an actionable engineering scope.

Best for

Architecture review, legacy assessment, security review, discovery or pre-build planning.

  • Technical discovery
  • Risk and constraint map
  • Written findings
  • Prioritized next-step plan
02

Build & Modernization

From $5,000 scoped engineering project

Delivery of a new system, major module, integration or modernization initiative with scope, milestones and acceptance criteria defined before implementation.

Best for

New products, internal platforms, integrations, workflow systems and modernization work.

  • Architecture and implementation
  • Milestone-based delivery
  • Testing and documentation
  • Deployment handover
03

Ongoing Engineering

From $2,500 per month

Reserved engineering capacity for systems that need continuous development, reliability work, maintenance and technical ownership.

Best for

Active products with a continuing roadmap, integrations, operational fixes and iterative delivery.

  • Planned engineering capacity
  • Change and release management
  • Technical maintenance
  • Regular engineering review
04

Enterprise Partnership

Custom contracted scope

A tailored engagement for complex systems, multiple integrations, stronger operational commitments or work that requires coordinated technical ownership.

Best for

Complex organizations, multi-system programs, phased delivery and contract-specific support requirements.

  • Custom scope and governance
  • Phased delivery plan
  • Contract-defined support
  • Architecture and roadmap reviews

Starting prices are indicative planning figures in USD. Final scope, commercial terms, third-party costs, taxes and support commitments are defined in the proposal or contract.

Proof of engineering

Built systems explain the work better than a package name.

Examples of the engineering concerns FireXCore works with in production-oriented software.

Enterprise procurement Active engineering

RMS

A procurement platform built around controlled workflows, sourcing, suppliers, proposals, financial operations, files, auditability and client interaction.

  • Workflow-driven business state
  • Server-side authorization boundaries
  • Audit-first operational design
  • Durable system integrations
Evidence-grade data infrastructure Open engineering

MailVault

A provider-neutral email archive designed around preservation, deduplication, evidence provenance and integrity rather than a mailbox-style user interface.

  • Raw message preservation
  • Content-addressed blob storage
  • SHA-256 integrity tracking
  • Replay-safe archival workflows

How pricing works

The quote follows the engineering reality.

Two projects with the same label can have very different risk, integration and operational requirements. These factors are evaluated before a final quote.

System complexity

Domain rules, workflow depth, state transitions and the amount of custom engineering required.

Integrations

External APIs, legacy systems, identity providers, payment systems and data migration requirements.

Data & security

Authorization boundaries, auditability, evidence, sensitive data and security constraints change the engineering scope.

Delivery constraints

Deadlines, phased rollout, migration windows and dependencies affect staffing and implementation strategy.

Operational responsibility

Build-only work is different from an engagement that also includes reliability, monitoring or ongoing engineering.

Existing-system condition

Greenfield development, modernization and rescue work carry very different discovery and delivery costs.

Engineering baseline

What every serious engagement should leave behind.

The exact depth varies by scope, but delivery should remain understandable and maintainable after the engagement ends.

Version-controlled delivery

Source changes are tracked and reviewable rather than delivered as opaque one-off work.

Documented scope

Scope, assumptions and acceptance boundaries are made explicit before significant implementation begins.

Appropriate test coverage

Testing depth is matched to the risk of the system and the operations being changed.

Security baseline

Authentication, authorization, sensitive operations and deployment exposure are considered as engineering concerns.

Handover clarity

Deployment, documentation and operational ownership are defined for the agreed scope.

Change traceability

Important engineering decisions and material changes remain understandable after delivery.

Commercial clarity

Questions that should be answered before work starts.

Pricing is only useful when scope, responsibility and assumptions are clear.

Contact FireXCore
Do you provide fixed-price quotations?

Yes, when the scope is bounded well enough to quote responsibly. Complex or uncertain systems normally begin with a technical assessment or discovery phase before a fixed project scope is issued.

Are the prices on this page final?

No. They are starting points for planning. Final pricing depends on system complexity, integrations, data and security requirements, delivery constraints and the level of ongoing responsibility.

Can FireXCore work on an existing system?

Yes. Existing systems are usually reviewed first so that architecture, code quality, deployment risk and hidden dependencies are understood before implementation commitments are made.

Do you still take website, WordPress or SEO work?

Selected digital-platform and growth engagements remain available, but they are scoped separately. The core pricing model on this page is intentionally focused on software systems, applied AI, infrastructure and technical assurance.

Are hosting, cloud, API or other third-party costs included?

Only when they are explicitly included in the proposal. Third-party services, licenses, cloud usage and external provider fees are otherwise treated separately.

Do enterprise engagements automatically include 24/7 support or an SLA?

No. Operational coverage, response windows and SLAs are contract terms. They are included only when the required coverage, responsibilities and commercial terms have been defined explicitly.

Start with the system

Your system probably does not fit a template. That is expected.

Bring the current state, the problem and the constraints. FireXCore will turn that into an engineering scope before implementation begins.
