Software Development
for Businesses
We build custom software, web applications, enterprise platforms, and internal tools tailored to the real needs of every business.
At BetaZetaDev we build software from the ground up for companies, startups, and organizations that need solutions tailored to their real processes.
We design, build, and maintain web applications, internal tools, enterprise platforms, and systems connected through APIs, automations, and modern infrastructure.
We don’t sell templates or generic solutions. Every project starts from the client’s actual goals and is built with scalability, maintainability, and long-term growth in mind.
What we build
Development process
A clear, iterative, results-focused process. We work with you at every stage to build software that actually delivers value.
Analysis
We get to know your business, your goals, and the technical challenges to define scope and priorities.
Design
We design the solution: architecture, user experience, and key flows before writing any code.
Develop
We build clean, scalable, maintainable software using best practices and the right technologies.
Testing
We thoroughly test every feature to guarantee quality, performance, and security on every release.
Deployment
We deploy to secure, monitored environments to ensure a smooth launch with no surprises.
Evolution
We evolve your software with ongoing improvements, technical support, and new features over time.
Agile, iterative methodology
Frequent deliveries, continuous feedback, and transparency at every step of the project.
Technologies we use
Real cases
How we built a complete REST API from scratch
A real, end-to-end walkthrough of designing and shipping a scalable REST API with FastAPI, PostgreSQL, and Docker — from architecture to production, with auth and testing included.
Read the case →What we learned building a real product, beyond the code
Writing code and building a product aren't the same thing. We share the business and product lessons we learned shipping software people actually use.
Read the case →How we cut hours of manual work with custom software
A real case: we automated part of WorkIO's technical support with custom software and AI, documenting the process to reduce the team's manual workload.
Read the case →Orientative pricing
Every project has a different scope. Before putting together a budget, we look at your goals, the features you actually need, and the current state of the project to give you a realistic estimate — no hidden costs.
FAQ
What kind of software do you build?
We build custom software: web applications, internal tools, admin dashboards, SaaS platforms, APIs, and system integrations. We adapt to each business's real problem, not a fixed service catalog.
Do you work on existing projects?
Yes. Many projects we take on already have a codebase in production. We review the current architecture before proposing changes and prioritize system stability while adding new functionality.
Can you build both the web and the mobile app?
Yes, we build both web and cross-platform mobile applications, and we can connect both to the same API and database to keep everything in sync.
Do you also handle maintenance?
Yes. After launch we stay available for maintenance, bug fixes, new features, and monitoring, depending on the level of support you need.
How do we get started?
