    You've got to the right place if you need a top notch specialist for the fair price. I have over 14 years of programming experience. I use PHP as my main language since version 4. I'm pretty sure I can reach an understanding with almost everyone. I worked as a Lead Full Stack Developer, so I know how to manage team as good as I know how to be a part of a team. It doesn't matter if you're a big company or you just need help with your own project, I'll do my best to make your wishes come true. I prefer to work on a backend, but I have lots of other skills. I can set up AWS infrastructure for you or just configure a Linux server; I can build both, backend and frontend; I can create a native iOS and Android app if you want. Almost any type of a third-party API is not a problem either, even without any documentation. You will be surprised of what I can do. One of my goals, besides the top code quality, is to build strong long-term relationships, because I am convinced that the better you know the project, the easier it's to work on it. I stay online most of the time, so you can be sure you will be able to reach me in any situation. Please, feel free to contact me. Hopefully, I will be able to help you and it will be the beginning of a mutually beneficial long-term relationship.

    Full stack web developer, integrity is one of my core values. If you are looking for someone you can trust who has been building custom web solutions for over twenty years, look no further. From one of my favorite reviews I've received here on Upwork - "I've never met such a skilled developer. I mean, we are talking world-class ladies and gentlemen! You are not going to discover a better developer anywhere else." More- "Joseph was kind, responsive, quick, direct, and receptive to feedback. If you have worked with other developers, you know how rare this is, and how important it is to find someone who truly cares about the quality of work they provide. He couldn't have been better to work with." "Joe is incredibly talented and an absolute pleasure to work with. He is our go-to guy for a variety of challenges and we have full confidence" "I really enjoyed working with Joseph. He was honest and direct with his communication. He didn't try to oversell his services. It was all about just getting the job done, doing it well, and communicating with me about what was going on throughout the whole process." --- Ultimately, good web dev service consists of not only coding, but also translating your needs into solutions, communicating effectively, training you how to use the software, and giving you confidence along the way. I'm usually building custom functions or altering existing functionality, developing themes, plugins, doing installations, configuration, debugging, quality control, etc. I'm here for my clients to find their way through web dev projects. If there is anything I can't do, I'm happy to handle bringing in help on that specialty. I will be honest with you! My skills include but are not limited to; - Web App development - Laravel development - WordPress development - Stripe integrations - Payment gateways - E-commerce - API integrations - jQuery - CSS - new fav = tailwindcss - AJAX - Security I'm able to help with system design and database design, user experience, and optimization. I offer functionality consulting and can help prepare detailed requirements documents for larger projects. I do my best to provide ideas to solutions - when there is no clear path, a bit of research and some creativity can go a long way. I'm happy to build one function, a module / plug-in / or extension, or an entire concept site with a full suite of features. Contact me to discuss your needs!

How to Hire Top Software Engineers
 




How to hire software engineers




Whether your goal is to develop a mobile app, build a dynamic SPA (single-page application), or create a domain-specific language (DSL) for your enterprise software, a software engineer can help you take your software project from conception to completion. 


So how do you find the right software engineer for your needs? What follows are some tips for finding top software engineering consultants on Upwork.








How to shortlist software engineering professionals




As you’re browsing available software engineering consultants, it can be helpful to develop a shortlist of the freelancers you may want to interview. You can screen profiles on criteria such as:


    

  • Technology fit. You want a software engineer who understands what you are trying to build and which languages, frameworks, and other technologies are required. 
    • 

  • Developer workflow. You want an engineer who can slide right into your developer workflow (e.g., project management tools, test suites, version control systems).
    • 

  • Feedback. Check reviews from past clients for glowing testimonials or red flags that can tell you what it’s like to work with a particular software engineer.
    • 









How to write an effective software engineering job post




With a clear picture of your ideal software engineer in mind, it’s time to write that job post. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.


Job post title


Create a simple title that describes exactly what you’re looking for. The idea is to target the keywords that your ideal candidate is likely to type into a job search bar to find your project. Here are some sample software engineering job post titles:


    

  • Software engineer needed for a fintech app
    • 

  • Seeking full-stack software engineer (LAMP)
    • 

  • Software engineer needed with DevOps and Agile/Scrum experience
    • 



Software engineer project description


An effective software engineering job post should include: 


    

  • Scope of work: From progress reports to well-documented code, list all the deliverables you’ll need. 
    • 



    

  • Project length: Your job post should indicate whether this is a smaller or larger project. 
    • 



    

  • Background: If you prefer experience working with certain industries, software, or technologies, mention this here.
    • 



    

  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.
    • 



Software engineer job responsibilities


Here are some examples of software engineer job responsibilities:


    

  • Manage the software development life cycle (SDLC) of a product
    • 

  • Design and develop software test suites
    • 

  • Monitor system performance 
    • 

  • Optimize development and deployment processes
    • 



Software engineer requirements and qualifications


Be sure to include any requirements and qualifications you’re looking for in a software engineer. Here are some examples:


    

  • Application-specific programming language (e.g., Java for Android development) 
    • 

  • Programming paradigms (e.g., object-oriented design)
    • 

  • Software development methodologies (e.g., Agile, Scrum, XP)
    • 

  • Familiarity with the SDLC (from requirements gathering to deployment and maintenance)
    • 

  • Code documentation
    • 











Software Engineer FAQs




What is software engineering?




Software engineering is the application of engineering principles to software development. Ever wonder what the difference is between a software engineer and a software developer? The software engineer is a software developer who also uses engineering principles to carry your software project through the software development life cycle. Software engineering consultants help businesses build well-documented, powerful software.


Software Engineering Tips and Best Practices


Don’t repeat yourself; automate


According to the DRY principle, “Every piece of knowledge or logic must have a single, unambiguous representation within a system.” In other words, if you find yourself repeating the same piece of code over and over again, chances are high that you could refactor it into more-efficient code. 


It turns out that the DRY principle can also be expanded beyond the code to the entire SDLC. If there’s something you find yourself doing repetitively, such as configuring your cloud resources, there’s a good chance that it’s worth investing a little extra time in automation tools to make your life easier (e.g., automating server provisioning with Ansible playbooks).


Consider DevOps—it’s more than a buzzword


With the way hiring managers and marketers throw the term around, you’d be forgiven for thinking DevOps was just a buzzword. But DevOps is more than a buzzword; it’s a culture in which the lines between the traditional roles of software development and operations (system/network/database admins) are blurred to achieve continuous integration (CI) and continuous delivery (CD). In practice, that means using the right combination of automation tools for your project to enable teams of developers and operations staff to collaborate more effectively. It’s not something you can achieve overnight, but taking small steps such as using a remote code repository such as GitHub or automating the more tedious aspects of your server provisioning with Chef can go a long way toward making your life easier. 


Test smart and test often


Encourage unit tests during development and regression testing before deployment. A well-documented test suite that grows with your application will ensure you’re able to update and maintain your application with minimal downtime and disruptions. It’s better to catch code-breaking changes before you push a build to production. 


Consider adopting TDD (test-driven development), an Agile development methodology that involves writing code iteratively in three steps:


    

  • Red: Write a test for a software feature that fails
    • 

  • Green: Write the minimum code needed to pass the test
    • 

  • Refactor: Rewrite your passing code to best practices
    • 



Not only will TDD help you maximize your test coverage, but it will also encourage your development team to write well-documented, modular, reusable code.
