Hello! I’m Alihan, a Power BI Developer, Data Visualization specialist, and Data Analyst focused on turning complex business data into clear dashboards, automated reports, and actionable insights. I help businesses replace fragmented spreadsheets, repetitive reporting tasks, and disconnected data sources with reliable Power BI dashboards and structured reporting systems. My work covers the complete business intelligence lifecycle, including data extraction, data cleaning, transformation, data modeling, DAX development, dashboard design, KPI definition, publishing, performance optimization, and ongoing reporting support. As a Power BI Developer, I build interactive dashboards for sales, finance, marketing, operations, customer performance, executive reporting, and internal business processes. I create Power BI reports that are visually clear, technically reliable, and easy for teams to use in daily decision-making. As a Data Analyst, I work with raw business data to identify trends, performance gaps, operational patterns, and growth opportunities. I use Power BI, SQL, Excel, Power Query, DAX, and Data Visualization techniques to transform disconnected datasets into structured insights and decision-ready reports. My Power BI and Data Visualization work includes Power BI dashboard development, interactive KPI dashboards, executive and management reporting, sales performance dashboards, financial reporting, marketing analytics, operational reporting, customer and product analysis, data cleaning, Power Query development, DAX measures, calculated columns, data modeling, SQL analysis, Excel reporting, ETL, automated data refreshes, Row-Level Security, API connections, database integrations, and dashboard performance optimization. I build dashboards around practical business questions. Instead of displaying data without context, I structure each Power BI report around the KPIs, comparisons, targets, filters, and trends that decision-makers need to understand performance and take action. My Data Visualization approach focuses on clarity, hierarchy, and usability. I select the right charts, layouts, drill-down paths, filters, tooltips, and visual interactions to help users understand performance quickly. I also keep reporting consistent across executive, departmental, and operational levels. As a Power BI Developer, I connect and model data from Excel and CSV files, SQL databases, PostgreSQL, MySQL, CRM systems, ERP systems, marketing platforms, advertising tools, cloud data sources, APIs, and multiple reporting files. I combine these sources into clear data models that support reliable dashboards and scalable reporting. I use Power Query to clean, merge, structure, and transform data before building the reporting model. I use DAX to create calculated measures, time intelligence, year-over-year comparisons, targets, ratios, rolling metrics, variance analysis, and business-specific KPIs. I also improve existing Power BI dashboards by fixing data model issues, rewriting DAX measures, simplifying report logic, improving refresh and load times, reorganizing visuals, correcting filters, and making the overall reporting experience easier to understand and maintain. Clients work with me when they need a Power BI Developer who can build a dashboard from raw data, a Data Analyst who can turn business data into actionable insights, or a Data Visualization specialist who can make complex reporting easier to understand. I also support DAX development, Power Query transformation, KPI dashboard design, SQL and Excel analysis, API and database integration, reporting automation, existing dashboard redesign, data model optimization, performance improvements, and structured reporting documentation. I work closely with stakeholders to understand what they need to measure, where their data comes from, and how the final dashboard will support decisions. I then organize the data, define the reporting logic, build and test the Power BI dashboard, validate the outputs, and document the system for future use. My goal is not simply to create attractive charts. I build Power BI dashboards and Data Visualization systems that help teams understand their business, reduce recurring reporting work, and make faster, more confident decisions. If you need a Power BI Developer, Data Visualization specialist, or Data Analyst for dashboards, reporting automation, DAX, Power Query, SQL analysis, Excel reporting, or business intelligence, feel free to invite me to your project.

Most clients come to me after struggling with slow development cycles, messy codebases, and APIs that break under scale - usually because the project was built without the right architecture from day one. I'm a Senior .NET Developer with 8+ years of experience building fast, scalable, production-ready backend systems using C#, ASP.NET Core, Web API, and Microsoft Azure. I also use AI-assisted tools like Cursor, Claude, and GitHub Copilot to move faster without cutting corners on quality. WHAT I BUILD REST APIs and scalable Web APIs using .NET 6 / .NET 8 Clean Architecture, CQRS, Domain-Driven Design, and SOLID principles Full-stack applications - backend in ASP.NET Core, frontend in React.js or Angular Microservices using Docker, Kubernetes, and Azure Service Bus Database design with Entity Framework Core, SQL Server, PostgreSQL, and Azure SQL Third-party integrations - Stripe, PayPal, Twilio, Plaid Background jobs, queues, schedulers, and event-driven processing AI-ASSISTED DEVELOPMENT I treat AI as a real productivity tool, not a buzzword. With Cursor, Claude, and Copilot in my workflow, I write APIs faster with less boilerplate, catch issues earlier through AI-assisted code review, and debug complex systems more efficiently - while I stay fully responsible for architecture, security, and final quality. You get the output of an optimized development process, at the same high engineering standard. WHAT YOU GET Secure APIs - JWT authentication, OAuth2, Azure AD integration Scalable, cloud-ready systems built for Azure Clean, well-documented code (Swagger/OpenAPI included by default) Tested code - unit and integration tests with xUnit / NUnit Long-term maintainability - versioned, structured for future scaling PROJECT EXPERIENCE -Built a HIPAA-compliant healthcare platform using .NET Core, ASP.NET Core Web API, and React.js, improving performance and data security -Developed microservices-based systems on ASP.NET Core and Azure, improving scalability and reliability -Integrated third-party APIs (Stripe, PayPal, Twilio, Plaid) to automate business workflows -Migrated legacy applications to modern .NET Core architecture on Azure, reducing infrastructure cost -Built enterprise platforms - CRM, LMS, SaaS, POS - using C#, ASP.NET MVC, and Entity Framework CORE TECHNOLOGIES Backend: C#, .NET Core, ASP.NET Core, ASP.NET MVC, Web API, Entity Framework Core Cloud & DevOps: Azure App Services, Azure Functions, Azure Service Bus, Docker, Kubernetes (AKS), Azure DevOps CI/CD Database: SQL Server, PostgreSQL, Azure SQL Frontend Integration: React.js, Angular, SignalR (real-time apps) AI Tools: Cursor, Claude, GitHub Copilot Testing & Auth: xUnit, NUnit, JWT, OAuth2, Azure AD If you need a .NET developer who understands both business requirements and solid backend architecture, send me your project details - I'll help you figure out the right approach and get it built right the first time.

I am a well-rounded senior-level IT consultant with very diverse skills & experiences in many industries and countries. I have a get-it-done attitude, and I look for creative ways to achieve a solution that means fewer headaches for the client. My experience starts from the days when DOS was all we had. This knowledge means I know what is really behind the window versus those that only see the window itself; the façade. Many people know how to drag and drop a button onto a form in the studio, but can they write the code to make it work on the backend without a WYSIWYG interface? I usually can. I once challenged a .Net programmer to create code, and I would write classic ASP with C# (on the backend), and it was faster to code and just as efficient and scalable. Back in the dBase days, I wrote an Indexing routine that was faster than the one built-in to the software. These days I prefer to have SQL Server on the backend. Excel, Access VBA are no problem. The 3 J's: JavaScript, jQuery, JSON are also no problem. I prefer to do remote consultations since I travel all over the world.
