Kevin T., freelance Solidity developer
Kevin T.

Freelance Solidity developer in Canada

Full stack and blockchain developer. Certified PMP with a decade of proven software development leadership. It was through a combination of The Audio Recording Academy ([TARA.ca](http://tara.ca/)), Ottawa Community Loan Fund ([OCLF.org](http://oclf.org/)), Invest Ottawa ([InvestOttawa.ca](http://investottawa.ca/)), N-VisionIT ([betterwebsites.ca](http://betterwebsites.ca/)), Carleton University ([carleton.ca](http://carleton.ca/)) and many others that I have built the breadth of skills needed to provide high quality mentorship to my students. I'm very happy to have the resources necessary to excel at my job teaching and helping people get their projects finished. Among other great experiences; I was lucky to spend 5 years working with 2 former winners of Top 40 Under 40 awards as ranked by the Ottawa Business Journal as a project manager and lead developer within a contract web and mobile applications development firm. While as a CodeMentor on this platform it's important that I've spent years working remotely with many teams of skilled developers, designers and system administrators to build a wide variety of tools for solving specific business challenges there's more to the story. I've also worked with musicians, event planners, studio managers and other artistic types in a wholey creative setting. While I do help with building marketing, sales and promotional websites my preference is for complex systems with multiple stakeholders exchanging highly detailed data. When these systems are designed and integrated really well – the labor savings or increased insights for the involved organizations can be huge. Above it all; I'm a maker looking for a challenge. I have built Arduino microcontrollers speaking Bluetooth to native Android applications, set up commercial websites using all sorts of different CMS systems, set up hybrid web apps compiling to either iOS or Android and all sorts of complicated combinations of the above. Lately; my work day typically consists of working directly with clients who are trying to solve a specific business concern or a hobbyist/entrepreneur working on a passion project. Often they just don't have the on-hand skillset to get it done and need a flexible helper who can step into many different rolls as needed for a project. You'll find that if we can agree on a project scope, price and deliverables that I'm very passionate about achieving the deadlines we agree on. I've worked separately as both lead developer on complex projects and project manager on similarly complex projects. This allows me to confidently estimate for how long work is likely to take. I try to provide buffer time for delays or mistakes; but if time does run low or there are competing objectives I make sure they're communicated early and risk points are identified. During the academic season I like having the opportunity to work with new developers where I can help them to either understand then solve a problem or get an unnecessary roadblock out of the way so they can get back to solving the problem rather than fighting one of the many frustrations of learning how to think like a programmer. I look forward to hearing more about your project and discussing how I can help make it into a reality.

FAQs

Why hire a Solidity developer?

In today’s world, most companies have code-based needs that require developers to help build and maintain. For instance, if your business has a website or an app, you’ll need to keep it updated to ensure you continue to provide positive user experiences. At times, you may even need to revamp your website or app. This is where hiring a developer becomes crucial.

Depending on the stage and scale of your product and services, you may need to hire a Solidity developer, multiple developers, or even a full remote developer team to help keep your business running. If you’re a startup or a company running a website, your product will likely grow out of its original skeletal structure. Hiring full-time remote Solidity developers can help keep your website up-to-date.

How do I hire Solidity developers?

To hire a Solidity developer, you need to go through a hiring process of defining your needs, posting a job description, screening resumes, conducting interviews, testing candidates’ skills, checking references, and making an offer.

Arc offers three services to help you hire Solidity developers effectively and efficiently. Hire full-time Solidity developers from a vetted candidates pool, with new options every two weeks, and pay through prepaid packages or per hire.

If you’re not ready to commit to the paid plans, our free job posting service is for you. By posting your job on Arc, you can reach up to 350,000 developers around the world. With that said, the free plan will not give you access to pre-vetted Solidity developers.

Furthermore, we’ve partnered with compliance and payroll platforms Deel and Remote to make paperwork and hiring across borders easier. This way, you can focus on finding the right Solidity developer for your company, and let Arc handle the logistics.

Where do I hire the best remote Solidity developers?

There are two types of platforms you can hire Solidity programmers from: general and niche marketplaces. General platforms like Upwork, Fiverr, and Gigster offer a variety of non-vetted talents unlimited to developers. While you can find Solidity developers on general platforms, top tech talents generally avoid general marketplaces in order to escape bidding wars.

If you’re looking to hire the best remote Solidity developers, consider niche platforms like Arc that naturally attract and carefully vet their Solidity developers for hire. This way, you’ll save time and related hiring costs by only interviewing the most suitable remote Solidity developer candidates.

Some factors to consider when you hire Solidity developers include the platform’s specialty, developer’s geographical location, and the service’s customer support. Depending on your hiring budget, you may also want to compare the pricing and fee structure.

Make sure to list out all of the important factors when you compare and decide on which remote developer job board and platform to use to find Solidity developers for hire.

How do I write a Solidity developer job description?

Writing a good Solidity developer job description is crucial in helping you hire Solidity programmers that your company needs. A job description’s key elements include a clear job title, a brief company overview, a summary of the role, the required duties and responsibilities, and necessary and preferred experience. To attract top talent, it's also helpful to list other perks and benefits, such as flexible hours and health coverage.

Crafting a compelling job title is critical as it's the first thing that job seekers see. It should offer enough information to grab their attention and include details on the seniority level, type, and area or sub-field of the position.

Your company description should succinctly outline what makes your company unique to compete with other potential employers. The role summary for your remote Solidity developer should be concise and read like an elevator pitch for the position, while the duties and responsibilities should be outlined using bullet points that cover daily activities, tech stacks, tools, and processes used.
