-
How long does a digital engineering engagement typically take?
A lightweight MVP typically takes 8 to 16 weeks. Mid-complexity enterprise applications take 4 to 8 months. Large multi-module platforms may require 9 to 18 months depending on integrations, team size, and feature scope.
-
What does Strategy & Experience Design cover?
Strategy & Experience Design covers product strategy, UX research, UI design, customer experience mapping, and rapid prototyping, so a concept is validated with real users before a single line of production code gets written.
-
Can you modernize or re-engineer our legacy software?
Yes. Application Modernization covers cloud migration, re-engineering, API enablement, and a move to microservices where it fits, improving agility and performance without disrupting the business running on the system today.
-
What's included in Web Application Development?
Web Application Development covers secure, high-performing applications built on modern frameworks, cloud infrastructure, and APIs, with a responsive interface designed to work consistently across desktop, tablet, and mobile browsers.
-
Do you build native or cross-platform mobile apps?
Both. Mobile App Development covers native iOS and Android builds as well as cross-platform frameworks, with the choice driven by performance requirements, budget, and how much of the codebase needs to be shared.
-
Do you build AI capabilities directly into software products?
Yes. AI-Driven Software Development covers generative AI, agentic AI, large language model integration, machine learning, and intelligent automation, with governance and human oversight built into every implementation.
-
What does Digital Product Engineering actually cover?
Digital Product Engineering covers end-to-end product engineering, agile delivery, and cloud-native architecture, taking a product from a validated concept to a production release and continuing to improve it after launch.
-
What engagement and pricing models do you offer?
We offer Fixed-Price for defined scope, Time & Material for agile sprints, a Dedicated Engineering Team for long-term product ownership, and a Managed Engineering Retainer for post-launch maintenance and continuous feature delivery.
-
How does DevSecOps & Platform Engineering fit into delivery?
CI/CD automation, infrastructure as code, and Kubernetes-based platform engineering run inside the same pipeline as the build itself, with continuous monitoring in place, so security and reliability aren't a separate step bolted on at the end.
-
Can you integrate our systems and consolidate our data?
Yes. Data & Integration Engineering covers API development, ETL pipelines, data lakes, and real-time data integration across ERP, CRM, and third-party systems, so decisions get made on data that's actually current.
-
How do you handle security and compliance requirements?
We follow OWASP Top 10 secure coding standards, implement OAuth 2.0 and OIDC for identity, use Snyk and SonarQube for dependency and code scanning, and build for GDPR, HIPAA, and PCI-DSS compliance from the architecture stage.
-
Do you provide QA and ongoing application support after launch?
Yes. QA Engineering & Support covers automated testing, performance and security validation, continuous quality engineering, and proactive application support, so problems get caught before your users find them, both before and after launch.
-
How do you protect our intellectual property?
We execute detailed NDAs and IP assignment agreements before project kickoff. All code is maintained in private repositories with strict role-based access, and full IP transfer to the client is included in every engagement.
