I'm a software engineer having +30 years of experience building a wide variety of software applications like enterprise, desktop, web applications, content management, distributed systems, business management, UI components, data services, client applications, service integration, engines and many others. My dominant languages were C++ and C# and I've been using ASP.NET MVC/ .NET CORE / REST WEB API's for about 9 years for developing backend software and web applications applying for most of the standard coding design patterns and agility. like data access repositories, dependency injection, MVC, factories, SOLID principles and others. I’ve a good knowledge and experience implementing micro services using clean code architecture and all its related topics like layering, DDD, CQRS, message queuing, gateways, dependency injection, SSO authorization, design patterns. I have a good knowledge using RabbitMQ and SignalR technology for building a notification engine server that consumes events and re-publishing them by sending EMail and SignalR web sockets notifications to the users. I have a good working knowledge of the ABP framework and I used it to implement a full backend API’s for a project’s time tracking and management software project. Also I have a cloud native knowledge about Docker and Kubernetes for building containerized applications and services connecting them together. I 'm experienced using EF Core both DB first and code first and migrations, I use fluent validation for entity validation and also CQRS MediatR, AutoMapper for DTO to entity conversion and vice versa. Also I have some experience with AWS serverless computing using .Net Core lambda functions and API gateways. As a front-end developer I’m using Angular 17, HTML, CSS, Webpack, JavaScript, typescript, jQuery, Ajax, RxJs, AngularJS and React and Redux for building modern SPA. I have a good experience in writing reusable front end components , services and directives like data-grid, dropdown lookup, partial reactive form’s dynamic generator, UI validation framework, etc. I have two Nanodegree from Udacity for "Web Development Professional" & "Front End Web Development Advanced".

I help software companies fix and scale the systems their business runs on. Recent example: I re-architected a payments platform that was failing at ~100 concurrent users into one reliably handling 10,000+ transactions every 15 minutes. Over 15 years I've architected and delivered backend systems for fintech, insurance, and healthcare — industries where reliability, security, and handling sensitive data correctly are non-negotiable. My core work: C#/.NET Core, ASP.NET Web API, Azure (App Services, Service Bus, Functions, Key Vault), SQL Server and PostgreSQL, and clean, maintainable architecture (DDD, microservices, SOLID). Clients bring me in for three kinds of problems: ✔️ A system that breaks, slows down, or fails under load — and needs someone senior to diagnose and fix it properly. ✔️ A new backend or API that has to be built right the first time, with security and scale designed in. ✔️ Ongoing senior architecture and hands-on development for a product that has outgrown its current setup. I also build AI-powered features into applications — agentic workflows and LLM integrations using the OpenAI and Claude APIs, and RAG-based functionality — engineered on a solid backend so they're reliable, secure, and maintainable rather than fragile demos. I take on a small number of engagements at a time so each client gets senior attention. With Expert-Vetted status, 100% Job Success, and 9,500+ hours on Upwork, you can expect senior-level work and reliable delivery. If you have a system that needs to work properly, let's talk.
