A comprehensive overview of all projects by Gergely Kovacs — apps, websites, tools, experiments, and more.
Gergely Kovacs is a Hungarian developer with roots in Nagydobrony, a small Hungarian-speaking village in Transcarpathia, Ukraine — a place where his family has cultivated and traded paprika for nearly thirty years. He now lives in the Debrecen area of eastern Hungary, building software across an unusually wide range of platforms and domains. He is getting married to Veronika in June 2026. He is bilingual in Hungarian and English, with Ukrainian as a third working language — a fact that shows up not just in his wedding app's trilingual guest system, but in the natural ease with which he writes commit messages, UI strings, and documentation in all three.
He teaches people around him to code (a student named Kinga learned Git basics through his patient "piros gombok" and "kek gombok" exercises), builds websites for family businesses (an HVAC company run by Kalman Kovacs, a window distributor tied to Oknoplast), and turns personal moments into software projects — his wedding invitation is a React app with per-guest personalized URLs and a hidden easter egg triggered by tapping the couple's names.
Gergely is a burst-mode developer. His commit timestamps tell the story: sessions routinely run past midnight, sometimes into 2 or 3 AM, punctuated by messages like "amazing drawing!!!!", "wow camera feed is amazing", "performance baby", and the occasional "omg - ready." He does not work steadily across days — he ignites. A single day on the Affinitext project saw him power through stages 3 through 8 of an entire iOS app. The Leader platform — a full FastAPI + Celery + Next.js B2B SaaS — was architected and wired up in six hours overnight. The Venturi crypto dashboard was built in twenty-two minutes.
His rhythm is clear in the heatmap above: intense purple clusters separated by valleys of grey. Late December and early January are almost silent — a holiday pause. Then February 2026 erupts with simultaneous work on a FastAPI crypto backend, a React news platform, a wedding website, and a YouTube Shorts automation pipeline. He routinely juggles three to five projects in the same week, switching between Swift, TypeScript, Python, and React Native without visible friction.
He is an early and aggressive adopter of AI-assisted development. Projects are scaffolded with v0.dev, iterated with Claude Code, and wired to Google AI Studio. His commit messages reveal a candid, sometimes comic relationship with his AI tools: "claude promised it will be good json now," "claude promised again, let's see the json fix," "lets see if it can one shot fixes - still testless blind operation boi." He doesn't worship AI — he negotiates with it, calls its bluff, and keeps pushing until the output works.
The flagship is Bonvo Ski Maps — a production iOS app shipped to the App Store with 107 commits across five months. It started as a MapKit experiment in July 2025 and grew into a full social ski navigation platform with offline maps, sensor-fused heading at 240Hz, live location sharing, group competitions, RevenueCat subscriptions, and Winter Olympics 2026 event integration. Around it orbit nine supporting projects: a corporate marketing site with programmatic SEO (90 auto-publishing blog posts), a partner onboarding portal, a React Native cross-platform port, an Expo experiment, 3D terrain prototypes, and the original BiOSnvo proof-of-concept that started it all with "slopes show up" and ended with "too mch research."
The second major body of work is the crypto news and trading intelligence platform — trut.hu (FastAPI backend, 75 commits) paired with TikTok-News (React frontend, 53 commits). Together they aggregate RSS feeds, classify and translate news with LLMs, generate TTS audio summaries, run AI trading bots with paper trading, stream Binance liquidation data via WebSocket, integrate Polymarket predictions, and gate premium features behind Stripe subscriptions. This system was attacked in production (a Redis exploitation incident on March 6, 2026), hardened, and kept running — a sign that it's not a toy.
Beyond these, the portfolio spans a legal document reader for iOS (Affinitext, 31,000 lines of Swift), a photography booking platform (FlashBook), an AI content studio (blogposter), a position-size calculator for crypto traders (UNO/RiskGuard, shipping as iOS app and Chrome extension), a multi-platform audio transcription service (MultiRecordings), a motion-controlled party game (Revolutionary/SpinSight), a self-healing AI code generator (slab), a Figma plugin for Hungarian typography, real estate scrapers, a Google Drive sync utility, and a family paprika brand landing page rooted in thirty years of tradition.
Genuinely productive across native iOS (SwiftUI, MapKit, CoreMotion, ARKit, SceneKit), modern web (Next.js, React, Vite, Tailwind, Supabase), Python backends (FastAPI, Celery, Redis, SQLAlchemy), and cross-platform mobile (React Native, Expo). Not a dabbler — ships real features in each stack.
Thinks in products, not just code. Bonvo Ski has a corporate site, partner portal, onboarding flow, subscription model, App Store metadata, and programmatic SEO strategy. TikTok-News has Stripe gating, newsletter signup, editorial boards, and analytics. He builds the whole business surface, not just the feature.
Ships fast. Entire prototypes materialize in single sessions. The gap between idea and working code is measured in hours, not weeks. AI tools amplify this but don't explain it — the speed comes from willingness to commit to a direction and iterate in real time rather than plan endlessly.
Uses AI as a genuine collaborator — v0.dev for UI scaffolding, Claude Code for iteration, Gemini for content generation, Whisper for transcription, DALL-E for images. Understands the strengths and limitations ("claude promised again") and routes around them.
Ski resort navigation, crypto trading intelligence, legal document management, photography booking, audio transcription, game development, typography tooling, wedding planning — not afraid to learn a new domain and build something real in it.
Trilingual (Hungarian, English, Ukrainian) with deep roots in both Hungary and Transcarpathia. Builds for Hungarian local businesses, writes Ukrainian wedding invitations, and documents code in English. This cultural fluency is a rare and underused asset.
Of 52 projects, only a handful have shipped to real users. Bonvo Ski Maps and oknoplast-alap are the clearest successes; most others stall after an initial burst. The pattern is: explosive start → working prototype → silence. The gap between "it works" and "people use it" is where most value is lost. Picking 2-3 projects and driving them to actual users, feedback loops, and revenue would compound more than starting 10 new ones.
The CLAUDE.md for Bonvo Ski Maps mentions a TDD approach (70/20/10 split), but commit messages like "still testless blind operation boi" reveal the reality. The Redis exploitation of trut.hu is another signal — production systems need hardening before they're in production, not after. Investing in test coverage and security practices early would protect the speed advantage rather than tax it with firefighting later.
The 90-post programmatic SEO blog on bonvo-ski-corporate shows awareness that creation without distribution is invisible. But this muscle is underdeveloped. The crypto platform could benefit from community building; the wedding-style personalized app concept could become a SaaS for other couples; the Figma plugin solves a real niche pain. The next level is spending as much energy getting things in front of users as building them.
The breadth is impressive but comes at a cost. Mastering one ecosystem deeply — say, the Apple platform (SwiftUI + CloudKit + StoreKit + WidgetKit + visionOS) or the Python AI/ML stack — would open doors that generalist breadth alone won't. The Bonvo Ski Maps work already demonstrates senior-level iOS capability; pushing into visionOS or advanced MapKit features could create genuine market differentiation.
Nearly every project is solo (the occasional "v0" or "alekpauls" aside). The talent for building fast alone is real, but the ceiling for solo work is lower than for teams. Finding a co-founder, contributing to open source, or even building in public to attract collaborators could multiply impact. The Bonvo Ski ecosystem is complex enough to benefit from a second pair of hands.
The combination of native iOS + AI integration + crypto domain knowledge + Central/Eastern European language skills is a genuinely rare profile. The trut.hu trading bot, the Bonvo Ski app, and the AI content tools each touch parts of this intersection. A focused product that combines all three — say, an AI-powered fintech tool for the Hungarian-speaking market, or a ski-tech product leveraging real sensor data — could be hard for competitors to replicate.
Gergely Kovacs is a builder. Not in the polished, pitch-deck sense — in the 2 AM, "omg - ready," ship-it-tonight sense. He carries the rare combination of product vision (he sees the whole business, not just the feature), technical range (he can build it on any platform), and raw speed (he can have it working by morning). The risk is that the same restless energy that spawns fifty-two projects in a year is also what keeps any single one from reaching its full potential. The best version of his future looks less like more projects and more like fewer, deeper, finished ones — with users, revenue, and a team around them. The talent is obvious. The leverage is in the follow-through.
