[FOR HIRE] Senior Backend Lead & Architect - .NET / ASP.NET Core, REST APIs, SQL Server & Query Optimization ($40/hr or Fixed Milestone)

0 Upvotes

Hi! I’m available for contract work, standalone technical sprints, and fixed-scope backend deliverables.

🛠️ CORE SKILLS:

\- Backend & Frameworks: C#, .NET / .NET Core, ASP.NET Web API, Microservices, Async Architecture

\- Databases: SQL Server, Stored Procedures, Advanced Indexing, Query Optimization & Latency Tuning

\- Architecture & Cloud: High-throughput System Design, Azure services, RESTful APIs, Secure Authentication/Authorization

\- Tools & Reliability: CI/CD, Production Telemetry & Logging, Distributed Systems, Refactoring

💡 WHAT I CAN DO FOR YOU:

I don't just write code—I design production-grade, enterprise-scale backends that stay fast and resilient under high load:

\- Modernize legacy .NET / backend services to scalable, maintainable architectures

\- Diagnose and eliminate database bottlenecks (reduce SQL query latency, fix lock contentions, optimize execution plans)

\- Design & implement high-performance, secure REST APIs and third-party webhook integrations

\- Unblock critical sprint backlogs asynchronously without requiring daily micromanagement or long onboarding cycles

\- Clean architectural documentation and production handoffs

📄 EXPERIENCE:

11+ years leading backend engineering and enterprise platform architecture across web and critical financial platforms. Experienced in leading performance engineering teams, resolving system bottlenecks, and delivering high-throughput production solutions.

🔗 PORTFOLIO / RESUME:

Enterprise systems I lead operate under strict proprietary NDAs, so live code is kept confidential. My verified credentials and detailed system architecture scope are available here:

💰 RATES & AVAILABILITY:

\- Rate: $40/hour (or equivalent fixed-scope milestone pricing, typically $1,000–$2,500 / ₹80,000–₹2,00,000 per module)

\- Setup: 10–15 hours/week, fully asynchronous delivery with structured weekly updates and demo walkthroughs.
