Gourish Julka — Backend & Systems Developer

Backend & systems developer. I build agentic backends, local-first platforms, and ML meshes that run without the cloud — hackathon-proven across desktop agents, in-editor execution engines, and rainfall detection from traffic cameras.

2026•AI / Desktop Agent

Blinky

Autonomous AI desktop tutor & computer-use agent. Dual-engine architecture (System 1 reflex fast-path + System 2 agentic loop), full Windows-to-Linux Wayland/Hyprland port, spatial OCR/@ref grounding, and an authenticated Expo mobile companion.

↳Architected a dual-engine agent loop (System 1 & System 2): built a fast-path reflex classifier that intercepts atomic system commands (volume, media, window management, lock) and executes them directly via blinky-daemon in <5ms without LLM overhead.

↳Engineered the full Windows-to-Linux port: built the pure-Rust blinky-daemon with native Hyprland/Wayland compositor bindings, PipeWire screen capture, kernel uinput virtual keyboard/mouse actuation, and ATSPI accessibility tree parsing.

↳Built the spatial computer-use perception pipeline: fused high-speed Tesseract OCR and OmniParser YOLO detection to index on-screen targets with stable @ref tags (@eN) and normalized bounding boxes, cached and attached directly to daemon frame buffers.

2025•Local-First / AI Platform

VoiceNotes

Privacy-first voice intelligence platform. Local-first tri-surface architecture (120Hz Expo Android app, Next.js 16 Neural Dashboard, Dockerized FastAPI backend), 4-field intent router RAG gate, faster-whisper, and Ollama-served LLMs running end-to-end with zero cloud dependencies.

↳Engineered a local-first tri-surface architecture: built a native Android Expo companion (React Native / Reanimated 4 at 120Hz), a Next.js 16 Neural Dashboard, and a Dockerized FastAPI backend serving local Ollama models (gemma4:e4b / e2b) and faster-whisper with zero cloud deps.

↳Designed a 4-field structured intent router: analyzes queries across needs_context, retrieval_query, actions, and answer_mode to gate RAG retrieval, prevent hallucinated citations on action requests, and enforce a client-side confirmation gate before creating notes.

↳Implemented multi-query hybrid search with Reciprocal Rank Fusion (RRF): combines pgvector semantic embeddings (nomic-embed-text) and PostgreSQL full-text search (tsvector) with citation verification ensuring only genuinely referenced notes attach to chat history.

2026•Systems / Autonomous Agents

Fermas

Pure-Rust autonomous AI agent runtime. High-throughput async actor model across 15 Tokio crates, byte-stable prompt caching, Ratatui TUI, JIT skill discovery, and native Linux desktop daemon.

↳Architected a modular 15-crate pure-Rust agent runtime on Tokio: decoupled state machines (fermas-core), model transport (fermas-llm), TUI presentation (fermas-tui), tool execution (fermas-tools), and subagent orchestration (fermas-orchestration).

↳Enforced strict prompt cache integrity: guaranteed byte-stable system prompts (SOUL.md, AGENTS.md) and strict user/assistant turn alternation to achieve 100% KV prefix cache hits across Anthropic, OpenRouter, and Ollama sessions.

↳Engineered a JIT skill engine with procedural memory: dynamic SKILL.md parsing with sandboxed WASM/C-ABI execution (wasmtime/libloading) and automated background curator usage telemetry.

2025•Full-Stack / Local-First

TheBlackBox

Local-first personal control center & modular widget platform. Freeform draggable canvas, schema-driven manifest widget engine, client-side AES security vault, and hybrid Supabase realtime sync.

↳Architected a local-first freeform widget canvas (react-rnd + Zustand) with multi-canvas switching, snap-to-grid, independent mobile deck ordering, and instantaneous optimistic persistence to localStorage.

↳Engineered an extensible manifest-driven widget engine: decoupled runtime execution from UI manifests, enabling schema-driven custom widget authoring, JSON import/export portability, and a custom API widget with deep JSON response path inspection.

↳Built hybrid cloud synchronization over Supabase PostgreSQL: implemented an offline mutation queue with debounced background pushes, soft-delete reconciliation, and Realtime WebSocket multi-device sync.

2026•Dev Tools / Simulation

SimIDE

Real-time C++ debugging & interactive DSA algorithm simulation directly in VS Code. Real C++17 execution over native GDB/LLDB via Debug Adapter Protocol (DAP), spring-damper physics canvas (d3-force), dynamic pointer discovery, and CRT boundary protection.

↳Built genuine debugger orchestration on the Debug Adapter Protocol (DAP): compiles native C++17 with debug flags (-g -O0), coordinates with GDB/LLDB across process boundaries, and captures live heap and stack state upon every step.

↳Engineered dynamic pointer discovery via source regex and line thresholds: automatically identifies and tracks pointer movements across function calls (printList, reverseList) without hardcoding variable names.

↳Developed a spring-damper physics canvas (integrated with d3-force): renders interactive bodies connected by elastic springs with Excalidraw-style pan/zoom (0.35x–2.5x), live pointer aliasing alerts, and pedagogical plain-English explanations.
