I'm a full-stack .NET developer with 11 years of experience based in Los Angeles. I'm a true full-stack developer, so I can work equally well on both front and back ends. I have experience in building applications from start to end, so I can take care of building almost any project, then supporting it for the long term. Here are some highlights from my background: - My tech stack is .NET, .NET Core, C#, SQL, Entity Framework, HTML, CSS, JavaScript, and Angular. - Experience with Azure and AWS. I'm especially good with Azure. I can setup Azure resources such as App Services, Function Apps, Azure SQL Databases, Storage Accounts, Key Vaults, Azure DevOps source control, deployment pipelines, etc. - Experience in working on large SaaS applications in healthcare, manufacturing, retail, human resources, and legal industries. - Experience in developing MVPs from start to end. - I write clean and understandable code with well defined architecture using best practices for software security. - Experience in SaaS and multi-tenant applications. - Great work ethics and honesty. If I don't know something, I'll tell you. If I messed up something, I'll tell you. My Certifications: - Microsoft Certified: Azure Developer Associate - Microsoft Certified: Azure AI Engineer Associate Also, I have a team of full-stack software developers. Building and supporting an application for a successful startup usually requires more than one developer. Building an application is like building a house. It usually requires a crew to complete. My team can join your project and help with building it, then support and enhance it in the future.

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.

Companies hire me to make the impossible possible. I have over 30 years experience working the technology landscape. - Project Management - Technology Integration - Software Development Lifecycle & CI/CD - Data Management & Analytics & AI - On-site and Cloud (AWS) - Client / Server - Cybersecurity After completing my degree in Bioengineering at the University of California, San Diego (UCSD) I started my career in Biotech and Computational Chemistry writing software utilizing early AI to perform chemistry and design drugs. I have been published for this work. I have also worked in clinical healthcare (Epidemiology and Infection Control), Supply Chain and the Finance industry where my technology skills matured to the level of architecting and beyond into the world of business leadership. My strength lies in listening to a client's challenge and then drawing on my experience to craft solutions. My data-driven expertise allows companies to manage and understand their data better. I think outside the box. If you are a small or startup company I can help you lay out your technology roadmap. If you are a mid-size or large company I can work with existing infrastructure and technology and make it better and more efficient. In all cases I can help recruit and mentor talent for companies to maintain their technology strategy. I am confident I can bring great value to your company so that you can impact the world! I look forward to our first conversation. (I am available on LinkedIn.)

𝗧𝗼𝗽 𝗥𝗮𝘁𝗲𝗱 𝗣𝗹𝘂𝘀 | 𝟭𝟬𝟬% 𝗝𝗼𝗯 𝗦𝘂𝗰𝗰𝗲𝘀𝘀 | 𝟭𝟯+ 𝗬𝗲𝗮𝗿𝘀 | 𝟴,𝟬𝟬𝟬+ 𝗨𝗽𝘄𝗼𝗿𝗸 𝗛𝗼𝘂𝗿𝘀 | $𝟮𝟬𝟬𝗞+ 𝗘𝗮𝗿𝗻𝗲𝗱 | I'm a senior .NET / C# developer and Azure cloud architect who builds and scales production systems for companies that can't afford downtime or rework — healthcare platforms, fintech products, e-commerce systems, and real estate/property-management software. If your project needs more than someone who writes code to spec — if you need someone who can architect the solution, own the delivery, and still be there for support six months later — that's the role I take on. WHAT I BUILD ──────────────────────── ✦ SaaS Platforms — multi-tenant, subscription-based .NET Core / Azure applications built to scale from a handful of users to enterprise volume ✦ Healthcare Systems — HIPAA-aware EHR/EMR platforms, HL7/FHIR integrations, and clinical workflow tools built to compliance standards ✦ Fintech & Payments — secure transaction processing, Stripe/PayPal integrations, reporting and reconciliation systems, PCI-conscious architecture ✦ E-Commerce Platforms — custom storefronts, order/inventory management, and integrations with payment gateways, CRMs, and ERPs ✦ Real Estate & Property Management Systems — listing platforms, tenant/lease management tools, and workflow automation for property teams ✦ AI-Powered Features — OpenAI/LLM integrations, intelligent document processing, and AI-assisted workflows added to existing .NET applications ✦ Legacy Modernization — turning outdated ASP.NET/VB.NET systems into maintainable, cloud-ready .NET 8 platforms without breaking what already works TECH STACK ──────────────────────── + Backend: C# · .NET 8 / .NET Core · ASP.NET Core · ASP.NET MVC · Web API · Entity Framework Core · LINQ · Blazor · SignalR · Microservices · REST & SOAP APIs + Frontend: Angular · React · TypeScript · JavaScript · HTML5 · CSS3 · Blazor UI + Cloud & DevOps: Microsoft Azure (App Services, Functions, AKS, Service Bus, Key Vault, Azure SQL) · AWS (EC2, Lambda, RDS, S3) · Azure DevOps · GitHub Actions · CI/CD · Docker · Kubernetes · Infrastructure as Code + Databases: SQL Server · PostgreSQL · Cosmos DB · MongoDB · Stored Procedures & Query Optimization for high-volume systems + Integrations: Stripe · PayPal · Twilio · SendGrid · OAuth 2.0 · HL7 · FHIR · CRM/ERP integrations HOW I WORK ──────────────────────── I stay involved from architecture through deployment — writing clean, documented, production-ready code, and communicating progress clearly at every step. I manage scope, timelines, and stakeholder expectations as carefully as I manage the codebase itself. Depending on what your project needs, I can work as a hands-on senior engineer, a solution architect, or a long-term technical lead. I'll tell you honestly, early, if I'm the right fit for what you're building. Send me your project scope and I'll respond within a few hours.
