SnapDump
Moodboard capture, organized and local.
SnapDump is a Chrome extension for designers, illustrators and art directors who collect references. In one action it grabs the highest-resolution images available on the current page, including long and lazy-loaded pages, drops the junk and saves the rest as an organized session.
It runs on your device. There is no account and no cloud in the core path.

30-second motion piece: saving images one by one, then SnapDump scanning a page, filtering, reviewing and exporting a session folder
What it does
01
Capture
Reads img, picture, srcset and useful CSS backgrounds, scrolls to load lazy content, and picks the largest real asset for each image.
02
Filter
Drops icons, tracking pixels and tiny images, prefers reference-sized images and removes obvious duplicates.
03
Review
A grid to preview, select and deselect, with filters by alt text, URL or bucket, and keyboard shortcuts.
04
Organize
Sorts images into Hero, Gallery and Details buckets with stable names and a manifest.
05
Export
Downloads a session folder or a ZIP with the same structure. Sessions can merge every open tab.

KAMKAM
Your phone as a real camera for webcam and streaming.
KAMKAM puts the camera you already carry to work as a real camera for calls and live streaming. It captures in 4K with the phone's own lenses, and Teams, Zoom, Meet, OBS and the Windows Camera app see it as a normal camera called KAMKAM.
Latency is very low: the phone encodes in hardware, the PC decodes on the graphics card, and the picture reaches every app at up to 1080p and 60 fps. A dedicated control panel on Android and a full control surface on Windows let you run the camera from either side, with no setup beyond opening two apps.
It links Android and Windows today, with iOS and macOS coming next.

KAMKAM on Windows streaming live from a phone over USB at 1080p, with camera controls, framing, scenes and link stats
What it does
01
Any route
Tries USB first, then USB tethering, Wi-Fi and Bluetooth. If a better route appears while streaming, it switches without dropping the call.
02
Meeting framing
Crops to a full 16:9 picture, follows your face as you move, or keeps a group of up to three people in the shot.
03
4K capture
At 4K 30, framing and zoom crop from a 4K picture, so the 1080p result stays sharp.
04
Background
A person-matting model runs on the PC's graphics card and blurs the room behind you or puts a picture there. Every app gets it.
05
Light
Backlight fix exposes for your face instead of the whole room. Face light adds a soft light on a dim face.
06
Phone microphone
Echo-cancelled, noise-suppressed Opus audio over the same encrypted link, held in lip sync with the picture.
07Ctrl+Alt+1 / 2 / 3
Scenes
Three slots each keep a whole look: quality, lens, zoom, framing, background, light and adjustments.
08
A second camera
Windows also gets KAMKAM 2: another lens of the same phone at the same time, or a second phone.
09
Heat guard
When the phone gets hot, KAMKAM steps down from 4K and 60 fps until it has cooled, so the camera keeps running through the call.
10
Control from both sides
A dedicated control panel in the Android app. On the PC: lens, zoom, focus, exposure, stabilization, low light and flashlight, plus brightness, contrast, saturation and warmth. Snapshots and MP4 recording.
Windows app: live from the phone over USB at 1080p, with camera, framing, scenes and link stats01 / 01

DESKTOP MEDIA WORKBENCH · C++20 · DEAR IMGUI
Menhir
Media mastered in one app.
Menhir is a Windows-first media player and broadcast workbench written in C++20. It puts a media player, an audio mixer, a broadcast studio and a recorder in one window and keeps them in sync.
Every tool is a panel. You can split, stack and resize panels, keep as many open as the job needs, and save the arrangement as a layout for playback, TV, recording or studio work.

NETWORK MONITORING AND DIAGNOSTICS · RUST · DIOXUS
Ultimate Network Manager
Is the connection healthy, and if not, where does it break?
Ultimate Network Manager measures latency, jitter, packet loss and gateway response continuously. Comparing the router with an internet target shows whether a problem is on the local Wi-Fi, router or cabling, or further upstream at the provider.
Samples, outages, alerts and speed tests survive restarts and export to CSV or a standalone HTML report. Every value on screen is a real measurement.

GAME ENGINE AND CREATION STUDIO · C++ · DIRECT3D 12
Fortece Engine
Every tool a game needs, inside one engine.
Fortece is a standalone game engine written in C++, with a complete creation studio built into it. Everything a game is made of is created in the same app: 3D models, materials, sound, animation, worlds, gameplay, visual effects and interfaces.
Studio has twelve modules that work on one shared world. Build a level, model a prop, give it a material and a sound, animate a character, write its gameplay, then press F5 to play it on the engine's own renderer and package it as a standalone Windows game.
The engine owns everything that matters: content, simulation and rendering run natively on Direct3D 12. The studio interface sits on top as HTML panels, with the engine's GPU viewports composed underneath them.

Fortece Studio Scene module with an imported character in the native viewport
Twelve modules
01
Scene
Build worlds from primitives, lights, cameras and player starts. Drop objects onto real surfaces, scatter patterns, organize the hierarchy and reuse whole assemblies.
02
Modeling
A full mesh editor: 18 base shapes, vertex, edge and face editing, edge loops and mesh tools. UVs and skin weights survive every edit.
03
Materials
Physically based surfaces from thirty node-graph recipes, imported texture sets and linked instances, with a live GPU preview.
04
SFX
A sound design studio with piano, keys, pad, lead, bass, pluck, bell and chip instruments, twelve effect recipes, MIDI input and a phrase recorder.
05
Animations
Pose and key rigs, build custom skeletons, drag a hand or foot and let IK solve the rest, compose clips and fire gameplay events.
06
Gameplay
Game logic as readable When / If / Do behaviors, with characters, inventory, abilities, objectives and NPCs that navigate, perceive and patrol.
07
VFX
30 effect bases, from campfires and lightning to volumetric explosions, with native gas and liquid simulation, ribbons, beams and mesh particles.
08
UI Studio
Menus and HUDs designed like in a design tool: auto layout, components and variants, themes, data bindings and motion.
09
Assets
Import Mixamo, FBX and glTF characters, attach animation batches, then search, tag and place everything from one library.
10
Play & Debug
Run the game with native rendering, input, collision, audio and UI, then pause, step and inspect it live.
11
Project & Build
Set controls, quality, saves and profiles, then package and launch a standalone Windows game.
12
AI
A Studio chat connected to provider APIs and the native authoring tools, with validated edits and undo.

About
I'm a French developer based in Brazil.
Each project started as something I needed. I polished them so other people could use them: native apps, engines and web.
