Ring the bells that still can ring
Forget your perfect offering
There is a crack in everything
That's how the light gets in
— Leonard Cohenwork, experience and skills
This portfolio strives to comprehensively present my personality and work, but primarily focuses on professional activities in the field of software engineering and information technology.
At twelve, a cursor blinked on a dark screen and everything changed. Not a career choice — a recognition. This is where curiosity finds its form. What follows is a decade of that impulse: to take apart, to understand, to rebuild better than before.
The need for creation, curiosity, the need to understand the world around me, and a thirst for new knowledge—which from the earliest years found their most fertile ground in software, and informatics and computing in general.
At twelve years old began my daily journey through code and computer systems—from microprocessor architecture to the sophisticated levels of abstraction that characterize application software today.
After more than a decade of practical engagement with computers, and almost a decade of writing software, today I can present my technical knowledge as the result of years of consistent dedication to every aspect of software development—from basic logic and understanding hardware limitations to complex architectures of distributed systems.
This technical application finds its place, not only as one of the separate aspects but as part of the complete picture, whose all elements serve the ideal of a modern 'polymath' inspired by the ancient concept of a versatile person.
"I see myself as homo poeticus who seeks creative synthesis through all aspects of work.
The literary tradition that shaped my thinking runs through the French moralists and Russian maximalists in equal measure—André Gide's acte gratuit and the liberation of authentic action, Proust's obsessive archaeology of memory and time, Dostoevsky's unflinching descent into the cellars of human psychology where logic dissolves into paradox. Danilo Kiš taught me that Central European melancholy is not pessimism but precision—the refusal to simplify what resists simplification.
Philosophy functions here not as academic credential but as operational framework. Kierkegaard's leap remains the founding gesture—the recognition that at some point analysis must yield to commitment, that infinite reflection is paralysis dressed in sophistication. Nietzsche's will to power, properly understood as creative self-overcoming rather than domination, provides the engine. Sartre's radical freedom and its terrifying corollary—radical responsibility—eliminates the comfortable alibis. And Schopenhauer's pessimism serves as inoculation: having accepted the worst, one is finally free to work without illusion.
Music through the piano is thinking made audible—neo-classical structures that provide form while leaving space for experimental deviation. Billiards and snooker offer a different meditation: the precise gap between intention and execution, where geometry meets nerve and the cue ball reveals character. Chess strips away all excuses, leaving pure consequence. Tennis adds the body to the equation—discipline that cannot be theorized, only practiced.
The polyglot dimension—Serbian as the native tongue carrying Balkan complexity, English as the lingua franca of technical and intellectual exchange, French as the gateway to a literary tradition that refuses the Anglo-Saxon split between thinking and style—each language is not translation but transformation, a different mode of consciousness that makes certain thoughts possible and others unreachable.
All of this converges, or rather: all of this is the convergence. The code I write carries the same aesthetic demand as the sentence I construct. The architecture of a distributed system mirrors the architecture of an argument. There is no separation between technical and humanistic—that distinction belongs to an era of specialization I refuse to inherit.
Philosophy gives you the questions. Engineering demands the answers. Between the thinking and the building lives the work that matters — late nights, broken deploys, elegant solutions, and the slow accumulation of craft.
Every project begins as abstraction and ends as someone's reality. A clinic goes paperless. A shop opens online. A team communicates without friction. The measure of code is not complexity — it is the moment the tool disappears.
Technology only matters when it serves real people. These are the industries where I've helped local businesses replace manual processes with software that actually works for them.
Custom patient management systems replacing paper records—appointment scheduling, medical history tracking, automated reminders, and reporting dashboards for clinic owners.
Taking brick-and-mortar shops online with inventory management, local payment integration, order tracking, and sales analytics that shop owners can actually understand.
Native mobile applications that let businesses connect directly with their customers—booking systems, loyalty programs, push notifications, and real-time communication channels.
Replacing spreadsheets, phone calls, and sticky notes with custom CRM systems, operational dashboards, and workflow automation tailored to how each business actually operates.

I specialize in developing web and mobile apps end-to-end – frontend, backend and databases. That includes social networks, e-commerce systems and business applications. Core stack: React + Next.js & Node.js on web, React Native for mobile, PostgreSQL/MongoDB for data, AWS & Google Cloud for hosting.
I've been programming for almost 10 years – started at 12. I'm open both to freelance projects (1-6 months) and full-time roles. Comfortable joining an existing team, leading small squads or mentoring juniors – and I enjoy working with startups. I already work with partners across Europe, the US and other regions.
I always provide post-delivery support: bug fixes, minor changes and explanations on how to use the app. For bigger changes or new features we can plan additional phases. I can share live demos of past projects and arrange a video call to show you the code and architecture.
I'm happy to work with teams anywhere in the world and seamlessly fit your existing workflow. To get started just email contact@jjovan.com with your project idea – we'll organize a 15-30 min, no-obligation call to discuss scope and approach.
Available for projects requiring both technical depth and product vision—particularly those where the problem space has genuine complexity. I'm open both to freelance projects and full-time roles, comfortable joining an existing team, leading small squads or mentoring juniors.
