Design and build production-grade applications, scalable backend services, and API-first platforms using Python, FastAPI, C#, .NET 8+, React, TypeScript, PostgreSQL, Supabase, SQL Server, and AWS. Architect event-driven and serverless workflows with AWS Lambda, S3, SNS, SQS, RDS, and EKS to automate operational processes.

Built production-ready software for semiconductor-industry operations using C#, .NET 8, Blazor, APIs, and integration services. Participated in architecture and design reviews for scalable backend systems, service boundaries, data flows, and deployment approaches.

Built distributed industrial IoT systems across backend, frontend, device integration, and automation layers using C#, .NET 6-8, Python, React, TypeScript, Node.js, Linux, and Docker. Designed microservices, APIs, and event-driven integration workflows for real-time device data ingestion, protocol translation, configuration, monitoring, and distributed application communication.

Built healthcare and pharmacy-related web and desktop systems using .NET 6, C# 10, Angular, TypeScript, Entity Framework, SQL, Azure, Docker, and API integrations. Designed backend business services, data-access layers, authentication workflows, and integrations for business-critical operational processes.

Built and customized a multi-tenant recruiting platform for 8+ major corporate brands including Deutsche Telekom, Daimler, Porsche, Lufthansa, Beiersdorf, Continental, and PwC. Developed backend services and APIs with PHP/Symfony/Laravel, C#, Java, and Node.js and integrated HR systems, Elasticsearch, external platforms, and enterprise data pipelines.

Developed Java 8 and Spring microservices plus Angular/TypeScript frontend features for an enterprise platform focused on digitizing and integrating business data. Designed REST-style APIs and integration boundaries between frontend, backend, Microsoft Office APIs, and external applications.

Led development of automation-heavy .NET and web systems that transformed email, CRM, customer-order, and telephony data into structured operational workflows, reducing repetitive manual work. Built a scheduled email-ingestion engine running every 10 minutes and designed SQL Server/T-SQL pipelines that converted unstructured customer and order messages into normalized, queryable operational data.

Built and maintained web, desktop, database, and operational workflow applications using C#, ASP.NET Web Forms, SQL Server, JavaScript, AJAX, XML, IIS, and web services. Converted manual property-claims processing activities into database-backed digital workflows and consolidated a 6-application process into 1 AJAX-based web application.

Advanced study in software engineering, algorithms, application architecture, multimedia systems, and artificial intelligence, with emphasis on robust, maintainable, and scalable software solutions.

Comprehensive foundation in software development, computer networks, algorithms and data structures, software architecture, systems analysis, technical planning, and structured problem-solving.
