Building Rust-based systems for LLM training and evaluation. Designing advanced coding assessments around Rust internals whilst mentoring engineers on systems programming best practices and memory safety patterns.

• LLM Training Systems: Engineering Rust-based systems for training and evaluating large language models, focusing on performance-critical data processing pipelines and model evaluation frameworks.
• Technical Assessment Design: Designing and maintaining advanced coding assessments around Rust internals including ownership, lifetimes, async programming, and unsafe code patterns for evaluating systems programming expertise.
• Technical Mentorship: Leading live coding sessions, workshops, and technical evaluations for distributed engineering teams. Mentoring engineers on systems programming best practices, concurrency patterns, and memory safety.
• AI/ML Collaboration: Partnering with AI/LLM teams to refine training datasets and improve Rust-specific model training, contributing domain expertise in systems programming to enhance model quality.

Built Farm Direct marketplace platform from zero to production - architected evolution from Laravel monolith to event-driven microservices supporting polyglot autonomous services that increased farmer sales by 60% over 18 months across 4 countries.

• Multi-Region System Architecture: Designed fault-tolerant platform serving 10,000+ users across Kenya, Uganda, Tanzania, Peru with 99.5% uptime. Implemented comprehensive monitoring with error tracking (Sentry) and multi-region uptime monitoring achieving sub-200ms response times.
• Microservices Migration: Architected transition from Laravel monolith to polyglot event-driven services (PHP/Node.js/Rust), enabling autonomous team deployment and eliminating system-wide failures. Each service independently deployable with dedicated databases and API contracts.
• Performance Engineering: Migrated Node.js analytics service to Rust/Tokio achieving 3x throughput improvement with 60% memory reduction. Implemented async SQS consumers processing 1000+ messages/minute with custom retry logic and exponential backoff.
• Infrastructure as Code: Cost-optimized cloud deployment on VPS infrastructure with Docker containerisation. Designed auto-scaling policies and implemented blue-green deployment strategies reducing deployment downtime to zero.

Rust TUI application with modal state management and responsive terminal rendering. Demonstrates systems programming with complex event handling, memory-efficient string processing, and cross-platform binary distribution.

• TUI Architecture: Built with Ratatui and Crossterm for cross-platform terminal rendering with Vim-inspired modal interface
• Async HTTP: Tokio runtime for non-blocking HTTP requests with Reqwest client, supporting custom headers and request bodies
• State Management: Complex modal state handling with event-driven input processing and memory-efficient response caching

OAuth 1.0a implementation with Twitter API v2 integration. Multi-interface architecture (CLI + HTTP server) showing systems design thinking for different access patterns.

• Dual Interface Design: Axum web server with Tokio runtime serving JSON API endpoints alongside CLI interface
• Configuration Management: Serde-based TOML serialization with validation and secure credential handling
• Cross-Platform Distribution: Automated binary builds for Linux x64, macOS x64/ARM64 with static linking support

High-throughput Rust service using Tokio for concurrent SQS message processing. Handles business events (ORDER_PLACED, USER_REGISTERED) with fault tolerance and backpressure management.

• Performance Metrics: Processes 1000+ messages/minute with 3x throughput improvement over Node.js predecessor
• Fault Tolerance: Custom async retry logic with exponential backoff and circuit breaker patterns
• Memory Efficiency: 60% memory reduction through Rust's zero-cost abstractions and efficient data structures

Fast, offline image processing using WebAssembly for near-native performance in the browser. Written in Rust for memory safety and computational efficiency.

• WASM Optimization: Rust compilation to WebAssembly with wasm-pack for size-optimized binaries
• Memory Safety: Zero-copy image processing with Rust's ownership system preventing buffer overflows
• Performance: Near-native speed image transformations without server round-trips or external dependencies
