4 steps to creating an ASP.NET Developer job description that fits your needs

Now it’s time to use our sample ASP.NET developer job description to create one of your own. With so many ASP.NET developers available, it’s important to determine exactly what you’re looking for in a developer so you can reflect those qualities in your description and screen your candidates well. The following steps will guide you through the process of writing your job description.

1. Determine what type of ASP.NET Developer you need

ASP.NET developers may specialize in certain areas, like web or mobile applications, full-stack development with an eye on security requirements, and more. If your business needs to follow HIPPA, GDPR, or other specific regulations, it’s important to hire an experienced developer to create compliant, fully-responsive websites and apps.

2. Employee vs. independent contractor vs. agency

You can hire an ASP.NET developer in-house, contract with one through a development agency, or work with a developer operating as an independent freelancer. Development agencies may have multiple developers with different specialties on staff, which can be ideal if you need developers who can implement various solutions. Hiring a developer in-house will be like bringing on another staff member, but you’ll need a continuous volume of work to justify this solution. Working with an independent contractor tends to be the most flexible arrangement and ideal for short-term and long-term development needs.

Worker classification can be tricky, so check out our compliance services resources page for more information, and be sure to ask your business lawyer any remaining questions you might have.

3. Experience

Think carefully about the amount of experience your ideal candidate should have. Highly experienced candidates can easily take on complex projects. A more entry-level candidate will require more supervision and training but may become an excellent long-term addition to your team.

4. Industry

ASP.NET developers work in many industries, including healthcare, finance, software development, and more. Each of these industries has its regulations and nuances, so if you’re looking for a developer who can easily step into the role, it’s often best to seek out a developer with experience working in your industry.

Next steps

Once you’ve created your job description, be sure to check out our list of top ASP.NET developers on Upwork. Each developer’s skills and experience are clearly listed, so you can easily tell which candidates are best for your needs.

The engineer you call when software, infrastructure, and networking all need to work together. 🚀 Senior DevOps Engineer | Backend Developer | Cloud & Platform Engineer Most technical problems don't exist in a single layer. An application is slow, but the root cause is the database. A deployment fails because of infrastructure. An API works locally but breaks in production because of networking. AI features underperform because the data pipeline was designed incorrectly. My background spans software development, cloud infrastructure, Linux systems, networking, automation, and AI integrations, allowing me to build and troubleshoot systems end-to-end. Over the last 5+ years, I have worked across AWS, GCP, Kubernetes, Docker, Terraform, CI/CD automation, backend APIs, distributed systems, AI-powered applications, and production environments supporting real business operations. 🎯 What I Can Help With ✅ Backend Development (Node.js, Python, Go, .NET) ✅ Cloud Infrastructure (AWS, GCP) ✅ Infrastructure as Code (Terraform) ✅ Kubernetes & Docker Platforms ✅ CI/CD Automation (GitHub Actions, GitLab CI, Jenkins) ✅ Linux Administration & Troubleshooting ✅ Database Design & Optimization ✅ AI & LLM Integrations (OpenAI, RAG, AI Agents) ✅ Monitoring, Observability & Reliability Engineering ✅ Performance Optimization & Cloud Cost Reduction 🔧 Clients Typically Bring Me In For • Building platforms that require both development and infrastructure expertise • Solving production issues that span applications, databases, networking, and cloud services • Modernizing deployment workflows and DevOps practices • Designing scalable cloud-native architectures • Integrating AI capabilities into existing products • Reducing operational complexity and cloud costs 💻 Core Technologies ☁️ Cloud AWS • GCP • Azure ⚙️ Infrastructure Terraform • Docker • Kubernetes • ECS • EKS • Linux 🖥 Backend Node.js • Python • Go • .NET • FastAPI 🌐 Frontend Next.js • React • TypeScript 🗄 Databases PostgreSQL • MySQL • MongoDB • Redis 🚀 DevOps GitHub Actions • GitLab CI • Jenkins • Monitoring • Observability 🤖 AI OpenAI • LLM Integrations • RAG Systems • AI Agents 💡 I work best with startups, SaaS companies, and engineering teams that need a single engineer capable of owning systems end-to-end—from architecture and development to deployment and operations. 🟢 If your project involves software, infrastructure, automation, or AI, let's talk.

Hi, I’m Shaneal Prasad - a Full Stack Web & Mobile Developer with 8+ years of professional experience building scalable, high-performance applications. Over the course of my career, I’ve worked on 13+ projects, including 7 delivered independently from start to finish. I’ve partnered with 6+ companies across industries like e-commerce, finance, dentistry, and data analytics, consistently delivering reliable and efficient solutions. What sets me apart I focus on building clean, well-structured, and bug-resistant systems. In my experience, most software issues come from a lack of clarity in design and execution. My approach emphasizes understanding the problem deeply before writing code-this results in faster development, fewer bugs, and long-term maintainability. Notable experience One of my most impactful projects was taking over a failing mobile app for a dentistry company. After their senior developer spent over a year without delivering a working product, I rebuilt the application from scratch-even without prior mobile experience-and successfully delivered it in just 4 months. The final product was stable, performant, and production-ready. I’ve also built advanced systems like a stock market bot and a mobile tele-dentistry platform, demonstrating my ability to handle complex, real-world problems. How I work I take ownership of projects and deliver results I communicate clearly and make thoughtful recommendations I respect your vision while ensuring technical excellence I prioritize speed without sacrificing quality My goal is simple: deliver high-quality software that saves you time and money. Tech stack Web Development React (JavaScript) .NET Core Dapper SQL / MongoDB Bootstrap Mobile Development Flutter React Native Node.js Firebase Cloud & DevOps AWS, Azure, GCP Git, GitHub, Bitbucket, Azure DevOps, SVN Industries I’ve worked with E-commerce Law Dentistry Finance Land Investments Stock Market / Data Analysis I’m currently available for new projects. While my rates may be higher than average, I deliver significantly faster and with higher quality-ultimately reducing your total cost. If you’re looking for a developer who takes your project seriously and gets it done right the first time, let’s connect.
