Process

01

Discovery

We map your current processes, the real problem, and the required outcome. We define scope, integrations, and acceptance criteria.

02

Technical Design

System architecture, data modeling, and functional wireframes. Everything is documented before a single line of code is written.

03

Iterative Development

2-week sprints with functional demos. You have repository access from day one. No black boxes.

04

QA & Deployment

Automated testing, security reviews, and production deployment. Team training and full technical documentation included.

FAQ

How much does it cost to develop a custom web application?
Costs depend on complexity and scope. A simple management module (1-2 features, basic integrations) starts at $2,500. A mid-range platform (multi-user, private area, billing, 3-5 integrations) ranges from $6,000-$15,000. Complex enterprise platforms (multi-role, public API, multi-tenant, payments, high scale) range from $15,000-$60,000+. We always provide a fixed-price quote after a complimentary 2-4 hour discovery workshop.
Do I own the code and the repository?
Yes, always. All code resides in a repository you own (GitHub, GitLab, or Bitbucket under your organization). We provide full technical documentation (architecture, decisions, runbooks), database diagrams, Postman collections for APIs, and a complete knowledge transfer at project completion. You retain total control and IP rights.
What technologies do you use?
We use a modern, proven stack with active communities: Next.js 15 / React for the frontend with App Router and Server Components; Node.js (Hono, Express, NestJS) or Python (FastAPI, Django) for the backend; PostgreSQL 16 for the primary database + Redis for caching and queues; Docker for deployment; CI/CD via GitHub Actions; and Vercel or Hetzner VPS depending on the use case. We use strict TypeScript across the entire project.
Can you integrate with our existing ERP, CRM, or software?
Yes. We connect systems through REST APIs, webhooks, GraphQL, SOAP (legacy), SFTP, or direct database access. We have extensive experience with HubSpot, Salesforce, NetSuite, QuickBooks, Odoo, SAP Business One, Shopify, and proprietary tools. Every integration is documented with clear diagrams and automated tests.
Do you offer ongoing maintenance and support?
Yes. Maintenance plans start at $149/mo, including security updates, monitoring (Sentry, Grafana), encrypted daily backups, and technical support with a clear SLA. We also offer on-demand blocks of development hours. Critical issues are corrected at no cost during the first 30 days after launch.
Do you work remotely with companies across the US?
Absolutely. 100% of our development projects are remote. We use a high-fidelity collaboration stack: Slack, Linear for task management, Notion for documentation, GitHub for code, and Zoom/Meet for weekly demos. You have access to the staging environment from the first sprint.
Do you follow Agile methodologies?
Yes. By default, we work in 2-week sprints with functional demos at the end of each. We use Linear to manage tasks with full visibility for your team. This allows for continuous priority adjustments without rigid contracts that force building obsolete features.
Do you guarantee delivery timelines?
We provide realistic estimates after the discovery workshop. For fixed-scope projects, we commit to deadlines with penalty clauses for delays on our end. For evolving projects, we set bi-weekly milestones. We don't over-promise to close a deal; we deliver what we commit to.
What level of security do you implement?
OWASP Top 10 compliance is our baseline: XSS/CSRF protection, input validation, rate limiting, SQL injection prevention, Argon2 hashing for auth, and secure JWT rotation. We use secrets management vaults and provide external pen-testing for sensitive enterprise projects.
Can you migrate from a legacy application?
Yes. We specialize in migrating from legacy PHP, Visual Basic, Access, massive Excel macros, or old Magento/WordPress setups. We follow a "strangler pattern" for gradual migration without service interruption, ensuring zero data loss.
