Source, diligence, and close early-stage investments in AI-native technologies, decentralized protocols, developer platforms, and compute infrastructure. Work side-by-side with founders post-investment on strategy, hiring, product roadmap, and scaling operations. 
Skills & Requirements: 
2–4 years in venture capital, startup operations, or technical role (engineering/product background strongly preferred) 
Deep understanding of AI models, blockchain infrastructure, open-source ecosystems, and compute markets
Proven ability to build founder networks and spot asymmetric opportunities early
Exceptional analytical skills, written/verbal communication, and comfort with high-uncertainty decisions
Self-starter who moves fast and doesn’t need hand-holding

Game Concept: “Reflex Arena”
Genre
Real-time competitive 1v1 / 2v2 skill-based action game
Platform
iOS (iPhone first, iPad optional)
Core Idea
A pure skill game where players compete in short, intense arena matches using precision timing, reflexes, and positioning — no RNG, no pay-to-win.
Each match lasts 60–90 seconds, making it ideal for mobile sessions while supporting competitive depth.
Core Gameplay Loop
Matchmaking
Skill-based MMR
Ranked & unranked queues
Arena Match
Small symmetrical arena
Players control a single character
Objective: score points by outplaying, not overpowering
Score & Progress
Win → rank up
Lose → learn (clear replay & stats)
Cosmetics only progression
Controls (Mobile-First, High Precision)
Left thumb: Movement (virtual joystick)
Right thumb: Aim + action swipe
Tap: Ability activation
Perfect timing windows reward precision (parries, counters)
👉 Designed to feel closer to a fighting game than a casual mobile title.
Mechanics (Skill > Stats)
Core Mechanics
Dash with cooldown (positioning skill)
Timed parry (frame-perfect defense)
Charged shots (risk vs reward)
Combo chaining (execution mastery)
No Randomness
Fixed damage
Fixed cooldowns
No crit chance
No loot boxes
Competitive Depth
Skill Expression
Reaction time
Prediction & mind games
Spacing & arena control
Cooldown tracking
Skill Ceiling
Easy to learn (1 minute)
Hard to master (1000+ matches)
Game Modes
Ranked Duel (Main Mode)
1v1
Best of 3 rounds
Seasonal leaderboard
Team Arena
2v2 coordinated play
Shared objectives
Training / Practice
Frame timing visualizer
Ghost replays of top players
Visual Style
Clean, minimalistic sci-fi arenas
High contrast for readability
60–120 FPS target (ProMotion)
👉 Performance clarity > visual noise.
Monetization (Fair & Competitive)
Skins (characters, arenas, effects)
Emotes / victory poses
Battle pass (cosmetic only)
🚫 No power boosts
🚫 No energy timers
🚫 No loot RNG
Technical Design (iOS-Optimized)
Native Swift
Metal / SpriteKit
Deterministic simulation
Server-authoritative logic
Rollback netcode (if real-time PvP)

I am seeking a world-class Systems Engineer / Rust Architect to build a proprietary asset extraction engine on the Solana network. This is not a "Web3 App" or a "DEX UI." This is a purely backend, low-latency machine designed to capture micro-value from market volatility.​The system mimics a "digital sluice," using high-precision math to harvest fractional differences that standard rounded-math bots ignore. We are scaling from a prototype to a 30-node distributed network managing 100+ concurrent execution "hands."​Core Technical Requirements​Low-Level Rust Mastery: You must be an expert in the Tokio runtime, asynchronous programming, and memory-safe mathematical operations.​Solana Network Physics: Deep understanding of the Sealevel runtime, custom WebSocket/Lumen bridges, and avoiding gRPC bottlenecks.​Jito & MEV Optimization: Proven experience with Jito Bundles, transaction shredding, and tip-optimization to ensure first-block inclusion.​Distributed Orchestration: Ability to architect a master-node system that manages 30+ regional nodes with seamless failover and zero-loss state management.​Precision Math: All logic must operate on u64 integers (Lamports) to avoid floating-point rounding errors. We do not "round" to the dollar; we capture the 9th decimal.​Key Responsibilities​Engine Hardening: Audit and optimize the core Rust logic for 0-latency execution.​Node Orchestration: Build the "Master Switch" to deploy, monitor, and update 30 nodes across global regions simultaneously.​The "Tax" Logic: Implement a secure, automated "sweeper" protocol that collects fractional value from all child-nodes into a master treasury without interrupting execution.​Redundancy: Ensure the system is "Anti-Fragile"—if a validator or node fails, the 50-drop safety protocol must trigger an instant failover.
