Job Success
Surat, India - 2:46 am local time
I work with SaaS founders, CTOs, and growth-stage teams that need real architectural depth — someone who can design the system, write the difficult parts, and integrate AI correctly. Not a ticket-taker: I own outcomes from database schema to production deployment.
HOW I HELP
Senior .NET Development : C#, .NET 6/7/8/9/10, ASP.NET Core, Web API, Minimal APIs, Blazor, SignalR, gRPC, Entity Framework Core, Dapper, Hangfire, MediatR. Clean, tested, maintainable code.
Solutions Architecture : System design, multi-tenant SaaS architecture, microservices vs. monolith decisions, Clean Architecture, CQRS, Domain-Driven Design, REST and GraphQL API contracts, security and compliance (GDPR, SOC 2 readiness), performance and scaling. I think in trade-offs, not just features.
AI Integration : OpenAI API, Azure OpenAI, Anthropic Claude API, RAG pipelines, AI agents and assistants, function/tool calling, prompt engineering, Semantic Kernel, Model Context Protocol (MCP), and vector databases (Azure AI Search, Qdrant, pgvector, Pinecone). I build production AI features inside real .NET and Next.js apps — not demos.
Technical Leadership & Advisory : Architecture reviews, tech-debt audits, technical roadmaps, AI adoption planning, and clear stakeholder communication. Google Project Management certified; Generative AI for Project Managers certified (PMI).
Frontend : React, Next.js (App Router and Pages Router), TypeScript, Tailwind CSS, shadcn/ui, server components, SSR/SSG/ISR, NextAuth.
Cloud & DevOps : Microsoft Azure (App Service, Functions, Azure SQL, Cosmos DB, Service Bus, Key Vault), Docker, IIS, Windows Server 2022, CI/CD with GitHub Actions and Azure DevOps.
Databases & Payments : SQL Server (multi-tenant schema design, query optimization), PostgreSQL, Redis, Cosmos DB; Stripe (subscriptions, webhooks, billing portal), ASP.NET Core Identity, JWT, OAuth 2.0, granular RBAC.
HOW I WORK
Every engagement starts with understanding the problem before any code is written. I map your goals, constraints, and existing system, then propose a clear architecture and a plan with milestones so you understand the trade-offs and the path before we commit. During the build I commit code regularly, keep it clean, tested, and documented, and give you progress you can actually follow instead of status-report noise. At handoff you receive maintainable code, documentation, and a system your own team can own and extend without depending on me.
I value direct communication and realistic timelines over overpromising. If an approach is wrong for your goals, I will say so and propose a better one you are paying for judgment, not just hours. My working day overlaps comfortably with US, UK, European, and Australian business hours, and I hold a 4–8 hour response time, so you are never left waiting on a critical decision. I treat your codebase, your deadlines, and your budget as if they were my own.
SELECTED WORK
- Architected a multi-tenant SaaS platform with SQL Server tenancy, Stripe billing, granular RBAC, AI credit metering, and Azure deployment.
- Extended a live 132-table SQL Server schema with full multi-tenancy and audit logging without modifying a single existing table.
- Built an autonomous AI agent system in .NET 8 using the Claude API, Hangfire background jobs, GraphQL, and OAuth 2.0.
