EXPERIENCE THAT BUILDS 01 — 06 ↓

01 / PERSONAL STORY

FROM SIGNALS TO SYSTEMS

Curiosity about how things work became a life’s work.

I was born in Sombor and shaped professionally in Novi Sad. I graduated in electrical engineering, specializing in electronics and telecommunications. Even as a student, I was drawn to the intersection of mathematics, signals, and software.

My first projects were research-focused: digital image and signal processing, fuzzy logic, and shape recognition. Then came mobile devices, communication protocols, client-server applications, and large business systems. Each step brought new responsibility—from implementing a component to shaping architecture, leading a team, and delivering a product.

“The most interesting systems don’t come from one big idea, but from many carefully connected decisions.”

June 2008 — present* BUSINESS SOFTWARE

ParagrafLex

A legal information system across platforms

An electronic collection of laws and regulations, official opinions, case law, model legal acts, tariffs, and other documents businesses need to operate in compliance. A central database and a suite of applications provide fast search, easy access, and regular content updates.

My responsibilities included project management, software architecture, and leading the development team. The system was delivered as web, mobile, standalone desktop, and network applications, with different data synchronization and distribution models.

02 / 06

JUN — NOV 2005. MOBILE INTERNET

mBid24

An eBay client for mobile phones

A client-server service that brought eBay listings to mobile devices. The J2ME client was designed to run across Nokia, Sony Ericsson, Motorola, and Siemens phones; the server used Java SE, Servlets, JSP, and JSTL.

I led the server-side work: designing and implementing registration and account management, an administrative CMS, a SOAP-like interface for the phone, and a proxy that handled cryptography, HTTPS connections, and GPRS traffic optimization.

03 / 06

APR — NOV 2004. EMBEDDED · TELECOM

PoC Client 1.0

Push-to-talk over a cellular network

The client combined SIP, HTTP, and RTP channels for call control, presence, contacts, chat, and instant messaging. It was developed in portable embedded C++, following IETF, 3GPP, OMA, and Siemens specifications.

I was responsible for the HTTP, RTP, and RTCP components, including the HTTP/1.1 subsystem, authentication, and RTP stream handling with reduced memory copying.

IMSSIPHTTPPRESENCE · CHAT · MESSAGING

SEP 2003 — MAR 2004. IMS

IMS Client 2.0

A communication client for UMTS

As part of an innovation team at the Faculty of Technical Sciences, I worked on the HTTP subsystem for an IP Multimedia Subsystem client. It combined SIP and HTTP for presence, contacts, chat, and instant messaging.

I led the design and implementation of HTTP/1.1 based on RFC 2616 and RFC 2617. I also contributed to SIP, HTTP, and XML parser/encoder design, from grammar through embedded C++ implementation and testing.

05 / 06

JAN 2003 — MAR 2004. RESEARCH

Shape Recognition — ASM

Active Shape Model for robotic vision

This postgraduate research project explored whether Active Shape Models could serve as a fast filter for recognizing shapes in images and support real-time processing. I compared existing filters, examined the algorithm’s potential, and designed and implemented a solution.

06 / 06

FEB — MAR 2003. DIGITAL SIGNAL

Multirate DSP

Sampling-rate conversion and filter design

This C++ application, built with MFC, comprised configurable modules for integer-factor downsampling and upsampling, rational-factor conversion, and Ad Hoc filter design. It showed hardware implementations and time- and frequency-domain responses; filters could be shaped by placing zeros and poles on the z-plane.

GRADUATION THESIS · MARCH — SEPTEMBER 2002.

FIRE fuzzy filter for image processing

This research compared conventional noise-removal and edge-detection filters with the fuzzy-logic FIRE filter. I implemented and tested the filter in MATLAB, added a genetic algorithm to generate its fuzzy rule base, and explored fuzzy edge detection on noisy images.

Member of the innovation team. Designed and implemented HTTP for an IMS client in embedded C++. Then worked on the PoC project, leading implementation of the RTP and RTCP protocols.

TELECOM

2004–05

Military service · return to study and development

After nine months of military service, I returned to the faculty and continued working with Zesium Mobile on mBid24, taking the lead on the server application.

MOBILE SOFTWARE

2006

JBlend / BenQ Diamond

Ported the Java VM to an Infineon platform. As test manager, I led Smoke and TCK testing, tested and reimplemented Low Level Graphics (JSR 118 MIDP), and debugged on target devices.

EMBEDDED

05 / LOOKING AHEAD

SAME PRINCIPLES. NEW TOOLS.

AI is changing how we work.
Engineering still takes judgment.

My experience took shape as mobile apps, the internet, and distributed systems were expanding. Today, AI opens a new chapter in that same story: how do we turn a new capability into a reliable part of a real product?

AI is a system capability

A model alone is not a product. You need quality data, a clear use case, integration into real workflows, and an understandable result.

Reliability is designed

As with protocols and business applications, we have to plan for errors, limits, security, privacy, monitoring, and recovery.

People remain accountable

AI can speed up research, development, and information processing. Judging whether a result is accurate and useful still depends on expertise and context.

This is my current professional perspective on AI—a continuation of my experience with systems and products, not a claim about a project absent from the original site.
