Frequently Asked Question

General Information

Who is Coretechs?

Coretechs is a US-based custom software development firm celebrating our 40th year! We specialize in full-stack development of mission-critical systems and mobile apps for private companies, government agencies, and startups.

Where is your team located?

Our team is primarily located in the Washington, DC metro area. Our headquarters is located in Kensington, Maryland.

What industries do you serve?

We have deep expertise across many sectors, including finance, healthcare, retail, manufacturing, and government contracting. Our flexible approach allows us to adapt to the unique regulatory and operational needs of almost any industry and in fact we’ve worked in almost every known vertical.

Custom Software Development Services

What technologies and frameworks do you specialize in?

Our team is proficient in a wide range of technologies, including:

Back-end: Python (Django, Flask), .NET, Java, PHP (Laravel), ColdFusion.
Front-end: React, Angular, Vue.
Mobile: iOS, Android, and cross-platform development via React Native and Flutter.
Databases: MySQL, Postgres, SQL Server.

Can you help with an existing/legacy system?

Yes. One of our core strengths is the ability to jump into an existing codebase. We can support whatever you have without the need for costly, time-consuming rewrites. If a previous developer leaves or retires we can rescue your system, stabilize it and grow your current platform without needing to start from scratch.

Do you develop mobile apps for both iOS and Android?

Yes. We build native and cross-platform mobile applications tailored for e-commerce, productivity, enterprise operations, and more. Using frameworks like React Native and Flutter, we can manage both your web and mobile presence with a single, unified team.

What is “Agent-Based” or AI-driven development?

We leverage modern AI assistants and agent-based development tools to supercharge our workflow. This allows our developers to write code faster, reduce repetitive tasks, and maximize your investment by delivering high-quality solutions in less time.

Project Management

How do I get a project estimate?

The fastest way is to “Talk to Gil.” You can call us directly at 202-540-0002. We skip the formulaic sales pitch and dive straight into your technical requirements to provide a realistic assessment and estimate.

Will I have a dedicated point of contact?

Absolutely. Every project is assigned a dedicated Project Manager and a Lead Developer. This ensures clear communication, accountability, and a deep understanding of your specific business goals.

What is your “Cybersecurity First” approach?

Security is not an afterthought at Coretechs. We integrate security into every phase of development —from SSL and user management protocols to proactive threat detection and routine patching.

Do you work with government agencies?

Yes. We are a trusted partner for government contractors and agencies in the DC area. Our US-based team understands the sensitivities of public sector work and delivers secure, compliant, and mission-critical digital solutions.
