A Tauri 2 desktop app for writing dense LLM agent prompts, annotating them with comments and reference images, and shipping the result straight into a Claude Code terminal session. Pairs with a stdio MCP server so a different Claude Code session can read every plan and annotation on demand.

• Tauri 2 app with a Rust command surface that enumerates live tabs across four terminal apps (iTerm2, Terminal, Ghostty, VS Code) using per app AppleScript dialects
• send_to_terminal handles text and images. Text via pbcopy plus AppleScript paste, images via clipboard «class PNGf» plus Cmd+V, non images via typed @filepath references

End to end LinkedIn job pipeline that scrapes postings, enriches them through headless Chrome, scores them with Claude, writes a per application PDF cover letter, then auto fills external ATS forms with a 3 tier hybrid system. DOM parsing first, API interception for React SPAs, Claude Vision as a last resort.

• 3 tier hybrid auto apply. DOM parsing, API interception (for React SPAs), Claude Vision fallback. Tiers 1 and 2 cost $0 per application, tier 3 about $0.50
• 82% success rate (9 of 11) on a March 2026 batch test across 11 ATS platforms (Greenhouse, Lever, Ashby, Breezy, Teamtailor, Personio, SmartRecruiters)

AI powered auto approval guardian for Claude Code that evaluates tool use requests in real time. Sentinel intercepts the JSON-RPC permission prompts, applies configurable risk heuristics and auto approves the low risk stuff, so I stay in flow without losing control of anything dangerous.

• Intercepts every tool-use permission Claude Code emits over JSON-RPC and decides in milliseconds
• Layered policy engine: file-path allowlists, command-pattern matching, token-budget guards

A treadmill facing ambient feedback system that watches a runner's knee flexion and gait rhythm in real time through two body worn IMUs (one on the tibia, one on the femur) and fades a big screen from green to yellow to red as form degrades. Good form keeps it green. A collapsing knee angle or rhythm drift turns it red with a gentle game over.

• Live knee flexion signal from two body worn IMUs at 100 Hz, fused through a complementary filter and streamed into a matplotlib live plot
• Concept sketched May 2024, active prototype January 2026. End to end data pipeline verified with sit to stand and running gait captures at the UT DesignLab

Multi game social platform for Texas Hold'em, Omaha and Short Deck with real time multiplayer over websockets. ELO based matchmaking, animated chip physics, in game chat and a full tournament bracket system, all in a responsive React UI.

• Sub-50ms event broadcast via Socket.IO across every seat at the table
• Hand evaluation via lookup-table algorithm — O(1) at showdown, no runtime iteration

Early stage B2B sustainability concept I scoped and submitted to the ELIAS European AI funding programme. EcoSynergy was framed as an AI driven ESG analytics product around satellite imagery, IoT energy data and climate datasets. This is a business development and funding pitch artefact, not a shipped platform, kept on the site as honest evidence of entrepreneurial work.

• Submitted as a formal funding pitch to the ELIAS European AI programme
• Scoped a satellite-NDVI + smart-meter + weather-forecast pipeline for SME ESG reporting

Git repository scanner and analytics dashboard that visualises commit frequency, contributor velocity, code churn hotspots and language breakdowns across all your repos. Talks to the GitHub API and renders rich filterable charts in a responsive React interface.

• Ingests repo metadata from GitHub REST + GraphQL into a local SQLite snapshot
• Commit heat calendars, per-author line-impact graphs and automated code-health scores

A 6 person HiFi HCI build. A wearable haptic coach for boulderers. A laptop watches the wall and the climber over a webcam, infers body pose and weight distribution, and fires a vibration on the exact limb that should move next across four ESP8266 armbands and legbands. It deliberately hints instead of solving.

• Demoed live on a lit hold bouldering wall at a Mad Rock climbing gym with a four wearable haptic coach
• Distributed six device network. Laptop plus ESP32 master plus four Wemos D1 mini (ESP8266) ESP-NOW slaves on arms and legs

• Transparent click-through Electron overlay pinned at 60 fps with zero input-lag impact
• C# companion does memory-mapped game-state reads for sub-frame event timing the public API can't expose

A 7 person portable anti theft smart bike lamp. The expensive brain (MCU, Li-Po, addressable LED strip, IMU) lives in a detachable module that slides onto a magnet plus pogo pin rail on a 3D printed fender. So a passing thief can only walk off with the cheap passive mount. Car like turn indicators and a brake light that intensifies on deceleration, all driven from three handlebar switches.

• Portable anti theft design. MCU, Li-Po, LED strip and IMU all live in a detachable brain that slides onto a magnet plus pogo pin rail. Only the cheap passive mount stays on the bike

• Documented FM broadcast capture in SDR# (89.0 MHz, Blackman-Harris-4 filter, clean carrier in the waterfall)

Contract project for a Turkish music producer. The team stood up its own GSM base station using full duplex SDRs and programmable SIM cards, spun up effectively unlimited phone numbers on demand, and drove a human looking Android automation farm through Android Studio plus Appium to seed engagement across Spotify, YouTube and Instagram. Framed honestly. What the tech actually does, not the marketing wrapper.

• Built a private GSM operator from full duplex SDRs plus programmable SIM cards. An effectively unlimited pool of real phone numbers for account creation and SMS verification
• Android Studio plus Appium farm driving dozens of phones through deliberately human paced interaction loops (scroll, watch, like, comment, sleep) instead of brute force actions

A 3D first person zombie shooter built in Ursina where you aim with your hand through webcam instead of a mouse.

• Redesigned chassis for weight distribution around the centre of lift to carry a Kinect depth sensor plus signal jammer payload

A 5 person interactive dinner table installation exhibited at Dutch Innovation Days 2022 in Enschede. A Kinect hidden inside the table watches whether visitors look down at a fake phone screen or up at each other, and a ceiling projector only paints food onto their plates while they keep talking.

• Exhibited publicly at Dutch Innovation Days 2022 in Enschede across a 5 day run
• Inverts the usual interaction model. The projector only renders food while visitors are NOT looking at a screen

A self built transistor pair astable multivibrator driving three high output IR LEDs fast enough to swamp IR remote receivers at short range. A classic electronics learning exercise in oscillator design, with every R and C value calculated against the multivibrator frequency math. Disables TV remotes and IR motion sensors. Does not touch WiFi, Bluetooth or cellular.

• Transistor pair astable multivibrator (2N4403 PNP plus 2N4401 NPN) driving three high output IR LEDs into the IR remote receive band
• Every R and C value calculated against the multivibrator frequency math rather than copied blindly. The point of the exercise was the oscillator theory, not the jammer

A Y1M2 Smart Environment project. An Arduino plus Grove sensor rig inside a potted basil plant feeds live temperature, humidity and soil moisture readings into a Processing desktop dashboard.
