Senior Software Developer | .NET 9 & Angular | AI-Assisted Engineering
I am a Senior Software Developer specializing in designing and building robust, scalable, enterprise-grade software solutions. My focus goes beyond just writing code; I am passionate about clean, highly structured software engineering that guarantees long-term maintainability and high availability.
I implement modern ecosystems based on Clean Architecture, Hexagonal Architecture, and Microservices, ensuring business logic is perfectly decoupled from infrastructure. I strictly follow a Code-First development methodology (EF Core) for database management to maintain absolute domain traceability, avoiding direct SQL editor manipulations.
Additionally, I stay at the absolute forefront of modern software engineering by integrating advanced AI-assisted development workflows. I leverage frameworks like the Model Context Protocol (MCP), OpenCode, Aider, Ollama, and the Gemini API to accelerate development cycles, automate repetitive testing, and enforce strict architectural rules directly within the codebase.
What I do best:
High-Performance Backend: Developing robust APIs with .NET 9, implementing CQRS patterns, and handling asynchronous messaging with RabbitMQ.
Modern Frontend: Crafting dynamic, optimized, and responsive web applications using Angular v21.
Multi-Platform Solutions: Building cross-platform hybrid apps with MAUI and Blazor for unified web and mobile experiences.
Complex Integrations: Implementing multi-tenant SaaS architectures, processing high-volume secure notifications, and integrating complex financial payment systems.
If you are looking for a disciplined Senior Developer who brings architectural order, rigorous technical excellence, and cutting-edge AI efficiency to your project, let’s connect and discuss your goals.

I'm Deepak Murali, a Computer Engineering student based in Dallas, TX and the founder of Applied AI Consulting — a development team specializing in AI-enabled web portals, custom web applications, and business websites.
I currently lead a team of student developers building production-ready software for real clients. Our active project is a full-stack client and agent portal for a Texas independent insurance agency — clients log in to view their policies, access documents, and get instant answers from an AI assistant, while agents manage tasks, leads, training, and AI-drafted follow-up emails from one central dashboard. Built with React, a secure backend, role-based access control, and Anthropic API integration.
What I build through Applied AI Consulting:
Client and agent portals for financial services, insurance, legal, and professional services firms
Business websites for local service companies that need a professional online presence
AI chatbots and assistants integrated into your existing workflows
Custom web applications and internal tools
My team delivers production-ready work — clean code, proper security, and real software engineering — at significantly below agency rates. You get senior-level output without the senior-level price tag.
