Work

Projects in production for clients, plus projects of my own.

Every project has its own page — what the client does, what had to be solved and how the site was built.

The case studies are in Serbian.

Services

Everything you need for a digital business.

01

Websites

Single-page, multi-page, e-commerce, news portals, 3D animated sites. Built from scratch to your specification.

02

Apps

Custom apps tailored to your business — inventory, POS, accounting, appointment booking and other workflows. They work even without internet.

03

Desktop apps

Windows apps, tools, automation. C#/.NET, Electron, native C++.

04

Excel automation

Macros and VBA tools. Hour-long processes execute in seconds.

05

Hosting and maintenance

I host the site on my own server and look after it: backups, a secure connection, updates and small changes.

06

Social media videos

Reels and short promo videos for Instagram, Facebook, TikTok and YouTube Shorts. Script, voice, editing and cover image.

07

Social media management

Instagram, Facebook and TikTok profiles, plus a LinkedIn profile and posts. A posting plan, post copy and scheduling.

08

AI images and visuals

Images and visuals for posts, reel covers and LinkedIn cards, made with AI tools and fitted to your brand.

09

Custom

Have specific requirements outside standard services? Let's discuss the implementation.

What's included

No hidden costs, no vendor lock-in.

What the work covers is written in the quote before we start, so there are no surprise add-ons later.

01

Hosting and security

I host the site on my own server. The secure connection (the lock icon in the browser) renews itself, with nothing for you to do.

02

Backups

The site is backed up automatically every night, and I check that the backup can be restored. If something breaks, I restore the last working version.

03

Google visibility

From day one the site is set up for Google search and a clean preview when shared on social media.

04

User training

I walk you through everything with real examples. You also get video tutorials and written guides for new team members.

05

Maintenance

Updates, small changes and checks that the site is working. We agree on the scope of maintenance to fit your needs.

06

Data protection

Your data and your clients' data are protected. You can request access or deletion at any time.

Working principles

5 steps, no surprises. Everything agreed upfront.

Development is fully open — you track progress through a link the whole time. You get the terms and the timeline in the quote before work starts.

01

Talk

Defining requirements.

02

Plan

Price, timeline, scope.

03

Live development

Track progress via a link.

04

Revisions

Delivering revisions.

05

Launch

The site goes live.

FAQ

Questions I get asked most.

How long does it take?
A simple site usually takes 1–2 weeks, larger projects longer — the exact timeline depends on scope and is stated in the offer. → Timeline guide
Do I own the source code?
Yes — the source code and the site are yours. No lock-in; you can move the site to another developer anytime.
What about hosting and maintenance?
I can host the site on my server and maintain it, or it can stay on the hosting you already have. The quote states exactly what the work covers.
Do you work remotely, outside Leskovac?
Yes, with clients across Serbia and abroad — fully remote. All communication is in writing over e-mail, and you follow progress live on a staging link.
How does payment work?
Everything is agreed upfront and put in writing — scope, timeline and terms. No surprises later.
