Questions before we build together

We design and build custom web applications, iOS and Android mobile apps, and digital products. We also provide IT consulting, architecture planning, system integration, deployment, and ongoing maintenance.

We work with startups, growing companies, and established organizations that need a new product, a modernization project, or additional engineering capacity. We shape the team and delivery approach around the product stage and business goals.

Yes. We can review an existing codebase, document risks and priorities, stabilize production issues, and plan a staged modernization. Access to the repository, infrastructure, and current documentation helps us assess the handover accurately.

We start with a discovery conversation about users, goals, constraints, timeline, and budget. We then clarify scope, recommend a technical approach, and agree on milestones, responsibilities, and communication before development starts.

A typical web or mobile MVP often takes around two to four months. Larger platforms may take six to twelve months or more. The final timeline depends on scope, integrations, design readiness, and review speed, so we confirm it after discovery.

We use regular progress updates, milestone reviews, demos, and a shared issue tracker. You will have clear points of contact and visibility into current work, decisions, risks, and the next deliverables.

Yes. We assess the impact of requested changes on cost, schedule, and technical risk before adding them to the plan. Small refinements can often fit into an active milestone; larger changes are planned as a new phase or revised scope.

Our common stack includes React, Next.js, Node.js, and TypeScript for web products, plus React Native and Flutter for mobile apps. We also work with cloud platforms and managed services such as AWS, GCP, Vercel, PostgreSQL, and Supabase when they fit the project.

Project ownership, repository access, design files, infrastructure accounts, and third-party licenses are documented in the agreement. For client-funded custom development, deliverables are transferred according to the agreed contract and payment terms.

We limit access by role, avoid sharing production credentials in ordinary communication, and use appropriate development and review practices for the project. If you have specific compliance or NDA requirements, we review them during discovery.

Cost depends on product scope, design complexity, integrations, platforms, and delivery timeline. After an initial conversation, we can recommend a suitable engagement model and provide an estimate or phased proposal.

Yes. We can provide post-launch monitoring, bug fixes, performance improvements, operating-system and dependency updates, and continued feature development under an agreed maintenance or product roadmap.
