Project details
This is web programming in JavaScript (a programming language that is commonly used to create interactive elements on websites). The services that I can do for you are (but are not limited to):
getting data from external sources (API, files, etc),
populating and manipulating select fields and/or any other kind of fields, lists,
validation,
creating HTML fields dynamically,
creating custom HTML elements, templates,
creating classes and modules, etc.
From external libraries, I will use Bootstrap 5.
About me:
I am a programmer (I live from programming income) for 20 years already.
I will never quit until we agree that the job is done or can't be done (I will never turn back on you and the job).
I am available before and after the job is done to discuss anything that you need.

To enable multiple deletion of claims
Dejan was excellent to work with. His skills, responsiveness and work product were top notch. He also showed a genuine personal interest in making sure everything went well and that we were satisfied with the end result. I definitely recommend Dejan to anyone looking to develop proprietary software.

Job Success
Tomislavci, Serbia - 4:32 pm local time
Programming since 2002, I build practical solutions around databases, web and desktop applications, data processing, APIs, automation, and AI integration.
My approach is simple: understand the real problem first, then build the cleanest solution for it.
Sometimes that means a PHP or C# backend. Sometimes it's a Python automation that replaces hours of manual work. Sometimes it's connecting APIs, processing thousands of records, scraping difficult data sources, controlling specialized hardware, or adding an AI layer that lets users work with their own documents and data.
And sometimes the best solution is a combination of all of them.
What I can help you with:
- Backend development with PHP, C#/.NET and Python
- REST API development and third-party integrations
- MSSQL and MySQL database development
- Full-stack and custom web applications
- Automation and scripting
- Web scraping, parsing and data extraction
- Data cleaning, transformation and processing
- Scheduled jobs and business workflow automation
- Windows and Electron desktop applications
- WordPress development and plugins
- Rapid prototyping and proof-of-concept development for web, desktop, automation, API, AI, and hardware-integrated solutions.
- Industrial automation software, EZCAD3 SDK integration, and custom laser-control systems
AI & OpenAI Integration
I build practical AI integrations, not AI for the sake of a buzzword.
I can integrate the OpenAI API into new or existing applications, including solutions using the Responses API, vector stores, document search, knowledge-base workflows, AI-assisted data processing, and custom backend automation.
I also work with Codex CLI and Cursor CLI, including Docker-based environments and automated development workflows. This is useful when you want AI to become part of an existing development or business process instead of replacing everything around it.
Data Scraping & Processing
Need data that isn't available through an API?
I have extensive experience with web scraping, parsing, extraction, data cleanup, transformation, large dataset processing, database imports/exports, and automated collection pipelines.
The goal is not just to collect data. The goal is to deliver structured, usable information that can immediately become part of your workflow.
Desktop, Electron & Industrial Integration
I have a long background in Windows and desktop development, including C#, Visual Basic .NET, VBA, Office Add-Ins, Classic ASP and VB6.
For modern desktop projects, I can also work with Electron when a JavaScript-based desktop application is a better fit.
For specialized industrial projects, I can work with the EZCAD3 SDK to integrate laser marking and control functionality into custom software and automation workflows.
Modernizing an old system does not always mean throwing it away. Sometimes the smarter solution is to extend it, connect it to newer services, automate the painful parts, and keep the parts that already work.
How I Work
I don't like disappearing into a project and returning with something completely different from what the client expected.
Good development requires good communication.
You can expect clear communication, realistic expectations, reliable delivery, fast problem identification, practical technical recommendations, and attention to detail.
If something is unclear, I ask. If I see a better approach, I explain it. If I spot a problem that could become expensive later, I bring it up early.
My goal is not just to complete a task. It's to leave you with something reliable that makes your work easier.
About Me
I'm also a certified railway engineer, and that engineering background strongly influences the way I approach software: understand the system, understand what can fail, remove unnecessary complexity, and build something dependable.
I'm a Microsoft Certified Professional (MCP) and work with C#, .NET, PHP, Python, JavaScript, SQL, MySQL, MSSQL, Visual Basic, VBA, WordPress, APIs, automation, data processing and related technologies.
I'm based in Serbia and speak English and Serbian. Vietnamese language assistance is also available when required.
My normal availability is 9 AM-6 PM Central European time, and I regularly work with clients across different time zones.
If you have a difficult technical problem, a repetitive process that should have been automated years ago, an API that refuses to cooperate, thousands of records that need processing, specialized hardware that needs software integration, or an idea that needs to become working software, send me a message.
There is usually a way to make it simpler.
