About Coretechs Consulting, Inc.

Full-stack web and mobile builds from Kensington, Maryland

Kensington, Maryland, is home to Coretechs Consulting, Inc., a web and app builder serving the Washington DC metro area and clients further afield. Its team is described as US-based and works on full-stack web applications built to a client's own specification, whether the job is to replace a legacy system or start from scratch. The firm reports more than thirty-five years of experience in software development, project management and business development.

Custom web applications and legacy replacement

The firm builds custom full-stack web applications, covering both the front end and the back end. Where a client has an aging system, the team can take on the legacy replacement, and where it does not, the team starts from scratch. Its developers use agent-based development methods to build a project quickly, and the firm says the aim is to meet the specification on time and on budget.

Mobile apps for iOS and Android

App development covers React Native applications and native apps for iOS and Android. The firm builds e-commerce, business and collaborative applications for any of these devices, and it works in the frameworks that suit each job. Its material mentions Ruby on Rails work for web applications, so the firm can take on projects in that stack as well.

Plugins, extensions and source code review

For clients with an existing site or platform, the firm builds plugins that add functions without taking the site down. Its developers work across the biggest platforms and adapt to what a client already has rather than replacing it. Source code review is a separate service in which the firm examines an existing codebase and reports on its condition. The firm also offers hardware and network support for a client's computer systems, so that the office equipment is looked after alongside the software.

Sectors and kinds of client

The firm names large organizations, small businesses and government entities among the clients it has built software for. It works with local contractors and government agencies in the DC area on complex and sensitive projects, and it says its US-based team keeps confidential work secure and in house. Web design firms, public relations agencies and media firms with limited development teams are another group, which the firm supports so that they can serve their own clients more widely. Private companies that want their systems extended beyond what they can buy off the shelf are a third.

Subcontracting and how a project starts

The firm also takes on subcontracted projects for other companies that need development capacity. A conversation starts with a call to the firm's president, who gives an on-the-spot assessment of a project, identifies the critical points and sets out the level of effort required.
