Building a web application is not easy, but it's definitely possible if you have the right tools and resources. To get started, you'll need to establish what type of web application you're looking to create (e.g., an e-commerce site or a content management system) and decide on the technology stack that will be used to develop it. Popular choices for a technology stack include Ruby on Rails, NodeJS, PHP/Laravel, ASP.Net Core MVC/WebAPI and Django/Python.
Once you have settled on your tech stack and determined the features required for your web app, it's time to start building! Here are some tips that can help make this process easier:

1) Use modular design - It's important to build loosely coupled modules in your app so that any changes made in one part don't impact the other parts of the app. This makes future development much easier and prevents bugs from cascading throughout the codebase as changes are made over time.

2) Leverage existing frameworks - Frameworks such as Bootstrap for front-end design or Laravel for back-end development can save enormous amounts of time by providing prebuilt components like layout templates or database models that can simply be integrated into your project quickly with minimal effort (if implemented properly).

3) Design a simple test suite – Well written tests provide early detection of errors before they reach production environments while also providing documentation regarding how different components interact within an application’s architecture used by app development company. Tools like Rspec enable developers to write detailed test suites prior to implementing code in order detect potential problems down the line when scaling up their applications later on down the road.

4) Choose a suitable hosting platform - When considering hosting options, identify which hosting solution would best meet your particular needs based both on budget constraints as well as performance requirements for scalability over time; popular platforms such as Amazon Web Services offer various levels of service depending shifting usage patterns among users or market demands down the line; these elastic services can accommodate increased demand without having manage too many server instances manually over long periods of time due their automated scaling capabilities which also reduces operating costs overall compared traditional hardware setups with limited scalability options built in by default

At each step along this process it is imperative maintain focus on quality control by double checking any new feature implementations against previously designed specifications; proper version control should also accompany all phases development which allows developers track progress more easily should any issues arise during deployment later stages; using services such GIT Github managing versions upgrades security patches much simpler manner when needed organized efficient way
