Design and ship software end to end — from bare-metal board bring-up and custom Linux distributions to cloud-connected backend systems and user-facing applications. Clean architecture, secure implementation, and delivery grounded in real-world hardware constraints. Comfortable owning the full stack — from kernel space to cloud infrastructure — so projects move without coordination overhead. 🎯 SYSTEMS THINKING - Scalable, modular architecture - Edge cases addressed early - Long-term maintainability over quick patches EMBEDDED LINUX & IoT - Custom Linux distributions (Yocto, Buildroot, BSP) — board bring-up, kernel development, driver integration across x86, ARM, and RISC-V - OTA update infrastructure, A/B partitioning, secure boot, TPM 2.0 encryption, read-only rootfs, fleet provisioning - Peripheral and connectivity protocols — UART, SPI, I2C, CAN bus, USB, BLE, MQTT, cellular, LoRa - Production targets — industrial gateways, POS terminals, medical devices, kiosk appliances, edge compute nodes AI & AUTOMATION - LLM-based systems, RAG pipelines, AI agents - OpenAI API and custom model integrations - Edge AI inference — TensorFlow Lite, ONNX Runtime on embedded targets - Workflow automation and data pipelines BACKEND & WEB - FastAPI, RESTful APIs, authentication systems - React and Next.js applications - Real-time and event-driven architecture - Full LEMP/LAMP stack deployment and optimization MOBILE APPS - API-first mobile architecture - Secure authentication and real-time features - Production-ready builds and deployment WEB3 - Smart contracts in Solidity and Rust - EVM and Solana ecosystems - DeFi protocols, token mechanics, on-chain integrations If you need someone who can take ownership, reduce moving parts, and ship cleanly without constant supervision, we'll work well together. mindre -

My expertise lies at the intersection of Scalable Backend Engineering (Node/Python/Go) and Modern AI Integration, and High-Performance Frontend System (Next.js/TypeScript), so helping companies transition from traditional architectures to AI-augmented ecosystems. As a Postgraduate in Project Management with a degree in Computer Science, I bridge the gap between complex technical requirements and strategic business delivery, ensuring that "Clean Architecture" always translates to ROI. 1. Core Strategic Stack - High-Performance Backend: Go (Golang), Python (FastAPI/Django), Node.js (TypeScript/NestJS). - Architectural Patterns: Microservices, Event-Driven Design (Kafka), gRPC, and Clean Architecture. - Modern Frontend: Next.js 19, React, and Performance Optimization for Enterprise Web Apps. 2. AI & Intelligent Systems - Orchestration: Advanced RAG (Retrieval-Augmented Generation), LangChain, and LlamaIndex. - LLM Integration: Expert-level implementation of OpenAI, Claude 3.5/4, and Gemini 1.5 Pro APIs. - AI DevOps: Vector Databases (Pinecone, Weaviate, Milvus), Prompt Engineering, and AI-driven automated workflows. 3. Infrastructure & Scalability - Cloud & DevOps: AWS (Lambda, EKS, RDS), Azure, Docker, and Kubernetes (K8s). - Data Layer: PostgreSQL (Advanced optimization), MongoDB, Redis, and Elasticsearch/Kibana. - CI/CD & Reliability: GitHub Actions, GitLab CI, TDD/BDD, and OpenTelemetry for observability. 4. Mobile & Cross-Platform - Hybrid Solutions: React Native and Ionic for high-performance iOS and Android deployment. 5. Leadership & Engineering Excellence - Team Governance: Mentoring senior engineers, implementing Agile/Scrum methodologies, and managing technical debt. - System Design: Designing for 99.9% availability, zero-downtime deployments, and global scalability. - Legacy Modernization: Strategic migration of PHP (Laravel/Symfony) monoliths into modern, distributed TypeScript/Go services. mindre -
