Why Companies Choose a Senior Web App Development Vendor
Most agencies staff junior developers to save costs. We staff senior engineers only.
When you hire a generic development shop, you often get a team with 2-3 years of experience. They need training and make design mistakes that cost time later. Our senior web app development vendor model means every engineer has 8+ years of experience and has shipped at least 20 products.
With senior engineers, we skip the learning curve. Your project starts producing value on day one. We have delivered 200+ products across 50 countries, and 98% were completed on time. The average MVP takes 12 weeks from kickoff to launch.
The Difference Between Us and Other Vendors
Many agencies promise senior talent but deliver juniors. We guarantee senior engineers on every project.
We have seen projects fail because the vendor used hourly billing and junior developers. The code was full of bugs, the timeline doubled, and the client had no ownership of the IP. We built our model to avoid these problems.
Every project gets a fixed price, a dedicated senior team, and full code ownership. We also handle compliance (HIPAA, PCI, SOC 2) and include 30 days of post-launch support. No surprises.

- Charges hourly with no cap

- All engineers have 8+ years experience
- Fixed price from $100K to $350K
- MVP in 8-12 weeks
- Built to meet HIPAA/PCI/SOC 2 standards

Our Process as a Senior Web App Development Vendor
We use a four-phase process that starts with a paid Roadmap to lock scope and price.
We do not start coding on a whiteboard. First, we invest 1-2 weeks in a Roadmap phase. This produces a documented technical plan, wireframes, and a fixed price contract for the build phase.
After that, we build your web app in 8-12 weeks. We use agile sprints, daily standups, and a live staging environment. You see progress every week. No black boxes.
What Ships with Every Senior Web App Development Project
You get full stack code, infrastructure, and documentation. No hidden handoffs.
We believe you should own everything we build. That is why every project delivers source code in your private GitHub repo, a running cloud environment, and written documentation.
We also set up monitoring, error tracking, and CI/CD so your team can take over after launch without relying on us. We provide a handoff session with your engineers.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or CircleCI
- Dockerized deployment configuration (Docker Compose)
- Cloud infrastructure on AWS (EC2, RDS, S3)
- Sentry error tracking and Datadog monitoring
- PostgreSQL or MongoDB database schema
- REST API documentation with Swagger/OpenAPI
- End-to-end tests with Cypress
- User authentication (Auth0 or custom JWT)
- 30 days post-launch support included
