You need software that solves a real problem, built right the first time, by people who understand your business and not just your stack. I'm Orest, founder of SoftDoes. We're a U.S.-based custom software firm working with: • Non-technical founders with a vision • Technical leaders who need help but not additional headcount • Business operators solving operational complexity Our team has delivered across healthcare, fintech, construction, legal, real estate, and regulated industries where compliance-readiness is required and getting it wrong isn't an option. Our clients tend to show up in one of three situations: they have a product vision and need someone to build it, they have internal engineering that's stretched too thin, or they have operational complexity that off-the-shelf software simply can't fix. We've handled all three. What we deliver: • Custom software and SaaS platforms built for scale • AI implementation and automation built into real workflows • Web and mobile applications • Cloud infrastructure on AWS, GCP, and Azure • Full-stack development across React, Next.js, Node.js, and Python What clients tell us, consistently: we listened, we delivered what we said we would, and they didn't have to babysit us to get there. A healthcare founder went from concept to a live, compliant product in under six weeks. A construction company replaced five fragmented tools with one custom operations platform. A fintech team cut onboarding time in half with an AI-assisted workflow we built in a single sprint. We work best with companies that are big enough to need real software and clear-eyed enough to know that building it wrong the first time costs more than doing it right. If that's where you are, let's talk. 🇺🇸 U.S.-based. U.S.-led. Kansas City, MO.

AI Engineering Lead and PhD researcher in AI/ML, certified in Claude by Anthropic. I design and ship production systems built around Claude: agents, RAG pipelines, and automations that actually make it to deployment Over the past 7 years I've helped more than 20 companies put AI into production across the US, Europe, and the Middle East. I've led engineering teams at startups large and small, and I bring a consistent track record as a high performer on the work I take on I post regularly on Medium, X, and YouTube on the latest in AI, ML, and tech, which keeps me on top of how fast the field moves, with an audience of over 10,000 across platforms. I share this work publicly partly because teaching a thing is the best test of whether you understand it What I build: - RAG chatbots and agents over your documents, PDFs, Notion, and knowledge bases - LLM fine-tuning on your domain data - Workflow automations that replace 40–80% of manual operations - Solution architecture, so you commit to the right stack the first time - Recovery work on stalled or underperforming AI projects Send over the project and I'll reply the same day with a plan, a clarifying question, or an honest pass

Software developer hiring guide

Software developers are the architects behind the applications and systems that drive modern business operations. From building customer-facing mobile apps to designing complex internal databases, these professionals translate functional requirements into reliable, efficient code. Hiring a skilled developer allows companies to accelerate digital transformation, automate workflows, and create custom solutions tailored to specific business goals.

What does a software developer do?

Software developers design, build, test, and maintain the software systems that power everything from mobile apps to enterprise platforms. Day to day, they write and refine code, troubleshoot bugs, and roll out new features while ensuring that the software is reliable, secure, and efficient.

They often work with programming languages like Python, JavaScript, Java, or C#, depending on the project and platform. Developers might build user-facing tools, back-end systems, or full-stack solutions that integrate both. Beyond coding, they collaborate closely with designers and other stakeholders to align software functionality with business goals.

The most important skills for a software developer include fluency in at least one or two core programming languages and familiarity with frameworks that support rapid development, such as React, Django, or Spring. Understanding how to work with databases — whether SQL or NoSQL — is another key skill. Developers must also be able to debug code effectively, optimize performance, and stay up to date with evolving technologies.

Soft skills play a big role in long-term success, too, and strong communication is essential. Many developers also maintain portfolios or GitHub repositories to showcase their projects, and certifications in areas like cloud computing or data structures can act as added proof of their expertise.

How to hire a freelance software developer on Upwork

Finding the right software developer requires a structured approach to connect with talent that matches your technical needs and project goals. Follow these steps to navigate the hiring journey on Upwork efficiently.

Step 1: Craft a targeted job post

The quality of your job post directly influences the caliber of developers who apply. A detailed listing helps you stand out to top talent and reduces time spent reviewing unqualified candidates.

  • Clearly outline your project goals, preferred tech stack, and expected deliverables; our software developer job description template can help you define the role clearly

  • Specify the type of application you’re building and the specific problem it solves

  • List must-have programming languages and frameworks, distinguishing them from nice-to-have skills

  • Define the project timeline, including key milestones and your preferred start date

If you'd like help turning your requirements into a clear posting, Upwork's Job Post Generator is powered by Uma, Upwork's Mindful AI™. Describe what you need, and Uma will draft a tailored job post.

Step 2: Filter and evaluate candidates

A systematic approach to reviewing applicants ensures you identify developers whose skills align with your project requirements.

  • Use Upwork's filters to narrow your search by expertise level, hourly rate, location, and past client ratings

  • Look for developers with verified work history in projects similar to yours, paying attention to client feedback on code quality

  • Check portfolios for live links or GitHub repositories that demonstrate clean, documented code

  • Prioritize candidates who have earned talent badges, indicating strong client satisfaction

Step 3: Interview your top choices

Interviews allow you to assess technical competence and communication style. For developers working on full-stack solutions, specific interview questions can help evaluate their expertise.

Step 4: Agree on scope and begin work

Establishing well-defined terms before development begins protects both parties and sets the foundation for successful collaboration.

  • Choose between fixed-price contracts for defined projects or hourly arrangements for ongoing work; Upwork's contracts and Hourly Payment Protection ensure you only pay for work that meets your standards

  • Set clear milestones for larger projects with specific deliverables for each payment release

  • Agree on a code review process and acceptance criteria before work begins

  • Establish a schedule for regular updates to track progress and address blockers quickly
