I’m a Software Engineer with over 3 years of professional experience, currently working at Microsoft, where I build and maintain production-grade backend systems used in real-world environments.
Over the years, I have built production-grade backend systems used in real-world environments at Microsoft, focusing on scalability, performance, and clean architecture. That experience shaped how I approach development today — focusing on building backend services that are stable, scalable, and easy to evolve.
I specialize in backend development using Java (Spring Boot) and .NET, with Python as a powerful tool for automation, data processing, and scripting when needed. My background in competitive programming strengthens my problem-solving skills and helps me write efficient, optimized solutions.
Beyond backend development, I’ve helped automate workflows that previously consumed hours of manual work — from data extraction and reporting to Google Sheets and Docs automation — allowing teams to save time and reduce errors.
What I can help you with:
- Backend & REST API development
- Designing scalable and maintainable architectures
- Refactoring and improving existing systems
- Performance optimization and debugging
- Database design and query optimization
- Backend tooling & internal automation
- Integrating third-party APIs and services
Technical Skills:
- Languages: Java, C#, Python, JavaScript
- Frameworks: Spring Boot, .NET, Node.js
- Databases: MySQL, MongoDB, Oracle
- Tools: Git, REST APIs, Google Apps Script
I care about writing clean, reliable code that not only works today but continues to work as your product grows.
If you’re looking for someone who thinks beyond just “getting the job done” and focuses on long-term quality and scalability — I’d be happy to work with you.

In this section, most freelancers try to showcase their experiences and certificates. They try to highlight the top-notch projects that they have worked on, but I want to say something different.
Upwork is full of talented people from all over the world, the market is so competitive that even the most experienced freelancers will struggle sometimes to win a new job.
So what makes me different? When people hire me, they don't hire a freelancer, they hire a team member or a business partner!
Most freelancers prefer to work on projects with very detailed scope and requirements, they try to fulfill these requirements as soon as possible, get paid, and move to the next job.
For me, I always enjoy working on projects that are just ideas or goals that my team tries to achieve. I always try to understand the background behind the requirements that I have, what we are trying to achieve, why we are trying to achieve it, and whether we are thinking of the best way to approach it or not!
I love making suggestions! I enjoy thinking together about the problems that my team faces and how to solve them! Many of my projects started as small tasks or bug fixes, then they turned out to be long-term business relations that lasted for years! Many of my clients praise me for being a detail-oriented person. I really enjoy working on hard unusual problems and finding solutions for them!
I started as a Google script developer, but I gained many skills working here. Many of my clients usually ask me to accept tasks even if they know that I don't have initial knowledge of how to complete them. I am always eager to learn new skills, work on new platforms and try new languages.
I have mastered Google script! I have used it in many Google apps automation workflows, completed external APIs integrations, built webhooks using it, and created lightweight web apps powered by it!
I have intermediate skills working with Python and Node JS. I have much experience working with SQL. I have worked with many visualization tools like Looker "Google Data Studio" and Microsoft Report Builder.
