Custom Software & Business Platforms
Launch a web application, connect business systems, or make an unreliable platform usable. Work spans the application, backend APIs, data, and deployment.
Explore platform development →Software Development for New Platforms and Existing Systems
Get a platform launched or make an unreliable system usable. Work directly with us on the application, backend, and integrations your business needs to move forward.
Take on a new build, an inherited codebase, or a defined system alongside your existing team. Agree the technical responsibility, delivery stages, and budget checkpoints before work begins.
What You Can Hire BVT to Build

Relevant Work, Not Just a List of Technologies
Internal Reporting Platform
Designed and deployed an internal analytics dashboard connecting multiple data sources and cloud services. Work included role-aware access, automated refresh workflows, performance, documentation, and handoff.
Read the platform delivery example →Industrial Field Operations
Architecture and implementation across a mobile application and backend API, including offline-capable synchronization, operational data, secure access, search, and cloud deployment.
Review the engineering responsibilities →Existing Product Delivery & Recovery
Joined NASA WeatherSats AR midstream, worked on cross-platform rendering and interaction, and resolved production defects. Responsibilities included release work, maintenance, and fixes across iOS and Android.
Read the project case study →A Clear Starting Point, with Room for Ongoing Delivery
We can act as your primary technical partner or own an agreed system alongside your CTO and engineers.
Start with the business outcome and what exists today. Agree the scope, access, responsibilities, spending cap, and review dates. Use demonstrations, test evidence, and documented findings to decide what comes next.
New builds and ongoing development are scoped in stages. If an existing product is stalled or unclear, a fixed-fee App Rescue Assessment is one way to establish the next step—not a requirement for every project.
Scope, budget, and continuation decisions remain between the client and Bill Vivino Technology. Long-term task-only staffing is outside this independent consulting model.
How engagements work · Pricing and engagement options
Discuss Your Software ProjectFocused reviews and smaller starting engagements
A review can address one release, integration, or operational risk before a larger commitment. Agree its outputs, scope, spending cap, and review date first.
Hourly reviews and implementation stages use 5–10 hour blocks where appropriate. A stage may span multiple blocks; the engagement names below do not promise completion within a single block.
iOS 27 Launch Audit
Prepare an existing app for iOS 27. Review compatibility, authentication, StoreKit purchases, accessibility, performance, and critical user journeys. Assess App Intents and Siri AI opportunities on supported devices.
Deliverable: A prioritized issue report, regression checklist, and release plan, with fixes scoped separately.
Review iOS consultingMCP Integration Sprint
Connect one valuable internal system to agents through the Model Context Protocol (MCP). Define narrowly scoped tools, user permissions, approval steps, and audit logs around a real business workflow.
Deliverable: One working integration, an end-to-end workflow demonstration, permission tests, and an operating guide.
Review AI integration consultingAI Production Safety Layer
Give an existing agent workflow measurable release criteria. Test tool permissions, prompt injection, data boundaries, failure behavior, human escalation, and limits on actions and spending.
Deliverable: A repeatable evaluation suite, deployment checks, incident logging, and a prioritized remediation plan.
Review production AI consultingiPhone Duo Adaptation Sprint
Prepare SwiftUI and UIKit apps for compact and expanded displays, Split View, multiple windows, and transitions between folded states. Review navigation, camera experiences, and continuity across layouts.
Deliverable: Adapted priority screens, state-preservation checks, and a validation plan tied to available simulators and devices.
Review mobile adaptation consultingHigh-Assurance Workflow Review
Review how fintech, healthcare, and other sensitive workflows verify requests before releasing data or taking action. Cover independent identity verification, request provenance, dual approval, policy rules, and anomaly detection.
Deliverable: A workflow threat map, control-gap assessment, and implementation priorities for stronger verification and audit trails.
Review workflow consultingDue-Diligence & Vendor-Risk Automation
Connect approved sources to legal, procurement, fintech, or compliance workflows. Automate evidence gathering, source-linked summaries, and review queues for due diligence, KYC support, and vendor risk.
Deliverable: One integrated research workflow with traceable evidence, exception handling, and a human decision checkpoint.
Review research automation consultingAI FinOps & ROI Review
Measure model usage, infrastructure commitments, latency, retries, and human-review costs against completed business tasks. Compare provider options, workload routing, caching, and fallbacks using the same quality benchmarks.
Deliverable: A cost baseline, provider comparison, prioritized savings plan, and metrics for deciding whether to expand or stop.
