Overall, the best experience I have had on UpWork" "This is the kind of freelancer that makes me glad to have joined the platform. Antonis is a consummate professional. Expert, punctual, supportive, flexible, communicative. The money I spent on this contract was some of the best I've ever spent!" "Would highly recommend. ...job...handled immediately and exactly as I wanted" "One of the most reliable contractors I have worked with. " "This man is a magician with algorithms." "Antonis is absolutely brilliant. Really attentive and really quick to get things done." "Technically astute." "Excellent work. Quick turnaround. Great attitude." That's a summary of all different feedback on completed jobs up to date, and that's the quality of service I love to provide. Short CV: For the last 8 years, I have being developing with Python, focusing on Data analysis projects. I'm accustomed with pandas, numpy and pretty much any related library. Before that, there is one decade's data-analysis and programming experience. I had been working with data collecting and processing tasks of all sorts using Microsoft Excel, Google Sheets, VBA macros, VB, VBA, Python, custom scripts and professional licensed tools for web scraping (automated website reading), PDF scrapping, and editing, OCR (scrapping from image files, using Tesseract and Finereader), file/data management, 10.000+ entries on each project. Some jobs are: listing all the online offered lessons of high schools of the country, regional statistics jobs (for my country's Statistics Authority), automating daily or weekly tasks with extensive error handling, lead generation, scraping search engine results, social media scrapping and automating windows applications. I use professional tools and custom developed solutions. I can speak directly to API, or read/parse the HTML output. I deploy to cloud (I use Amazon Web Services) for scaling and to perform geo-related searches, completing huge jobs in a few hours. Tech Background: I have hands on professional experience with AWS (EC2, S3, SQS etc), Latex, Matlab. I have strong Physics and Mathematics background. I speak HTML, JS, JSON, XML, C, C++, C#, Python (including Pandas, BeutifullSoup, boto3 for AWS, Django), VB, VBA (Advanced excel solutions), Google Apps Script, Bash (for SysAdmin tasks), CSS, and Windows Automation languages (i.e. Autoit). I have used hundreds of APIs including Google APIs (geolocation), and Twillio for marketing projects. I have delivered working solutions that use hundreds of proxy servers with management and recycling. More recently, I have used and implemented OpenAI Whisper and ChatGPT APIs to web applications. I have developed and deployed custom web applications based on Python (Django), SQL, Bootstrap4. I have included in, custom-developed genetic algorithms that perform live Operational Optimization. I offer services rather than products. I'll design the best applicable solution for your task from scratch, run it on my own infrastructure, and deliver the results to you within time. The solution can also be developed as your own custom Web Application or Software as a Service (SaaS), "fully managed" by me to ensure working for as long as you wish. This means a custom made website or web API that do what you want them to do. Hosted, secured, login-ready, will work on any device (Mobile/Tablet/Mac/Windows/Linux any flavor), at reasonable price for development and maintenance. Also, I'm available for support on short notice, as long as our contract is active. I can also comply with a Service Level Agreement (SLA). Through the years and through different projects and roles I have been in touch with hundreds of businesses and different verticals. The solutions I provide require me to understand the scope, and I find it easy to learn about and understand different subjects, be it Internet Marketing, SERP and SEO, Ships and Shipping Business, Agriculture, Financial and Tax, Logistics and Production Lines, Electronics and Robotics, on a level that allows me to easily communicate and requirements of new projects and tasks. I'm a fluent English speaker, and I'm available on Upwork chat even when I'm on mobile. This means I will respond to chat messages immediately or within 2 hours, 5 AM to 8 PM (UTC). I am also available at Skype, Slack, or Teamviewer, upon request (After Hire). I'm a business-minded trained professional that you can count to, to get the job done in the requested time, with 100% accuracy and attention to detail. Contact me today to make it work, together.

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.
