I work on .NET systems where things get complex, especially around ecommerce, payments, integrations, and performance. In one of my recent projects, I handled a system with around 25k+ orders per day, 100k+ basket operations, and about 250k product searches. My role was to find where things were slowing down and fix them properly, mainly at the SQL and API level. Most of my experience is in ecommerce and fintech systems. I’ve worked on inventory, orders, pricing, subscriptions, and payment flows like Stripe, PayPal, and Adyen. I’ve also worked with Amazon SP-API and other integrations, along with reporting and data-heavy dashboards. On the frontend side, I’ve built dashboards and internal tools using Blazor Server and Angular, mainly for admin workflows and reporting. Technically, I work with C#, .NET (Core and Framework), ASP.NET APIs, SQL Server and PostgreSQL. I’ve used Redis, Hangfire, and RabbitMQ in systems that needed to scale reliably. I also use AI tools where it makes sense, mostly for automation, data processing, and improving backend workflows. A big part of my work is performance tuning. Fixing slow queries, optimizing APIs, and improving systems under load. In some cases, I’ve reduced response times by around 40%. Usually, I get involved when systems start slowing down, integrations become messy, or things don’t scale properly. I focus on finding the root cause and fixing it instead of applying quick patches.
