Expert engineering. A practical way forward.

After you contact us

From the first conversation to getting started

We'll work through these steps together. We don't start paid work or ask for production access until we've agreed on the scope, permissions and commercial terms.

1. 01 / STAGE

   Send a safe problem summary

   Describe the system, what is failing or being built, the desired outcome, decision deadline and relevant constraints. Do not send credentials, classified material, sensitive client records or private source at this stage.

   Output: An initial inquiry that can be evaluated without privileged access.

2. 02 / STAGE

   Technical fit discussion

   Identify a likely engineering owner, system boundaries, risks, constraints, stakeholders and specialist needs. Use a Calendly meeting if an available slot suits both parties.

   Output: A decision on fit and whether more scoping information is required—not an automatic commitment.

3. 03 / STAGE

   Scope and written proposal

   Agree assumptions, deliverables, verification, milestones, client responsibilities, access, exclusions, commercial terms and any applicable confidentiality or security requirements.

   Output: A proposal for client review; no fixed price or schedule is implied before approval.

4. 04 / STAGE

   Approval and controlled kickoff

   Proceed only after scope approval, authorized access, appropriate agreements and specialist capacity are confirmed. Establish change control, environments, communication and rollback expectations.

   Output: A clear engineering owner, authorized work boundaries and a testable delivery plan.

5. 05 / STAGE

   Evidence-based delivery and handoff

   Provide agreed code, findings, tests, release or remediation evidence, operational notes and knowledge transfer. Record residual risks, exclusions and acceptance decisions.

   Output: Reviewable outputs rather than unsupported success claims.

Three ways to engage

Choose the kind of help you need.

A review, a build or help with an existing system. The examples below show what each can include. We'll put together a quote and delivery plan for your actual project.

A small assessment might be a single agreed fee. Bigger projects may use milestones or a separate support agreement. We'll be clear about what's included before you commit.

FROM REVIEW TO ENGINEERING DELIVERY

A useful first assessment can stand alone.

A diagnostic engagement produces findings and a decision. If you want help implementing them, that's a separate approved scope. Validation and longer-term engineering support are offered only when there is a clear need and available capacity.

1. 01 / STAGE

   Focused diagnostic

   Authorized review, reproducible evidence and ranked next actions.

2. 02 / STAGE

   Approved remediation

   Agreed code/configuration changes, review and regression tests.

3. 03 / STAGE

   Release validation

   Negative-path checks, acceptance evidence and recovery plan.

4. 04 / STAGE

   Optional support

   A separately scoped change or support cadence—not an automatic subscription.

Scope and commercial expectations

What goes into a project proposal?

Reviewing one API is different from building an app or modernizing an enterprise platform. Once we understand the work, we'll spell out the people, price, deliverables and timing in writing.

Who does the work

You'll know who's doing the work.

Our founder leads an engineering team that includes employees and independent contractors. We'll agree on the technical lead and contributors before we start. If the project calls for a specialist, a larger team or particular government qualifications, we'll confirm availability and approvals first. You'll know if we're not the right fit.

Engineering delivery

How we keep changes under control

We agree on the tests, reviews and release checks that matter for your project. Any managed support, private portal or independent certification requirements are separate.

Engineering life cycle

From the design to the handoff

We'll plan the change, build or review it, test the important cases and hand it back with clear notes. Where releases are involved, we'll agree on who can approve them and how to recover if something goes wrong.

Before you inquire

Frequently asked questions

Can you work with our existing Swift, Kotlin or API codebase?

Yes. Work can begin with a focused review of an existing iOS or Android app, its backend APIs and the workflows that need repair. A rewrite is not the default recommendation.

Engineering services

Do you provide mobile app development or only security reviews?

Both. Native iOS and Android implementation, backend/API engineering, platform reliability, security assessment and code review have separate scopes. A security review does not automatically include remediation implementation.

Android app development

Can we engage for a smaller assessment before a longer project?

Yes. A defined architecture review, investigation or targeted security assessment can establish findings and priorities before deciding whether implementation support is worthwhile. The actual deliverables and fee depend on scope.

Review methodology

What access or information should we send initially?

Initially, share a non-sensitive system overview, rough scope, target platform and timeline. Repository permissions, secure artifact transfer, confidentiality terms and access boundaries should be agreed before sharing private source, credentials or customer data.

Contact details

Is penetration testing performed only with written authorization?

Yes. Before active security testing, the client must establish ownership or authorization for the targets, permitted techniques and environments, exclusions, emergency contacts and rules of engagement. No production access is assumed.

Synthetic sample reports

Can we engage Demonic Binary for an MVP or enterprise modernization?

Yes, scope may start with an initial product slice, a focused modernization assessment, or defined implementation inside a mature production system. Actual staffing, acceptance criteria, environments, integration controls and commercial terms are agreed for the project.

Engineering capabilities

Do you support government or defense engineering opportunities?

We can discuss authorized public-sector work or subcontracting opportunities, subject to eligibility, procurement rules, data-handling requirements and any required personnel or facility clearances. We do not imply existing government contracts or classified-system access.

Government & defense requirements

Can you work with our team anywhere in the world, including on-site?

Yes. We work with clients worldwide, remotely or in hybrid engagements, and can arrange on-site engineering at your location when the work requires it. Schedule, travel costs, security access, local requirements and work authorization are agreed before committing to travel.
