🔥 AVAILABLE TODAY - June 26 🔥 I lead a boutique senior development team that helps SaaS companies, startups, and product teams build, rescue, and scale production-ready software. You work directly with me as the founder, AI/web technical lead, and delivery partner. I’m currently pursuing a Master’s in Computer Science with a focus on AI & Machine Learning, combining formal AI/ML depth with hands-on product delivery. My team handles implementation across frontend, backend, AI integration, QA, UX/UI, and DevOps when needed. This gives you senior engineering capacity without the hiring overhead or large-agency friction. We are a strong fit when the project needs more than “just coding”: architecture, product thinking, clean delivery, technical risk reduction, and a team that can understand complex business logic. What we build: • SaaS platforms and internal business systems • AI-powered web applications and automation workflows • Marketplaces, dashboards, admin panels, and client portals • Multi-tenant products with roles, permissions, billing, and workflows • REST APIs, backend services, integrations, and data-heavy systems • Legacy codebase refactoring, stabilization, and scaling • MVP-to-production builds for startups and product teams Core stack: Frontend: React, Next.js, Remix, TypeScript, Tailwind, Radix UI Backend: Node.js, Express, NestJS, FastAPI, Django, Laravel Databases: PostgreSQL, MongoDB, Redis, Prisma, SQLAlchemy, Drizzle AI: OpenAI, Gemini, Claude, Groq, embeddings, RAG-style workflows, summarization, classification, automation Infrastructure: Docker, AWS, GCP, Vercel, Render, Fly io, CI/CD How we work: Think twice and code once. My personal and my team's principle. That means we care about the product, data model, architecture, user workflows, security, deployment path, and long-term maintainability. Speed matters, but sustainable speed comes from clear decisions and fewer avoidable mistakes. You can bring us in for: • AI/SaaS code audit and technical due diligence • AI feature integration or automation sprint • Full-stack SaaS development • Backend/API architecture and implementation • Legacy system refactoring and modernization • Dedicated senior development capacity • Long-term technical partner retainer Best fit: • SaaS founders and product leaders • AI, marketplace, fintech, health, humanitarian, or operations-heavy products • Existing codebases that need clarity, stabilization, or acceleration • Teams that want senior ownership without hiring full-time engineers • Clients who value communication, architecture, and production quality

I am a Senior Embedded Linux Programmer and IT/Infrastructure Consultant with nearly 40 years of overall development experience. I specialize in getting tough hardware and networking projects off the ground—or rescuing existing projects that have hit a wall. Because my background spans the entire stack—from bare-metal custom Linux kernels to advanced enterprise server configurations—I can troubleshoot and build systems that most single-discipline developers cannot. Here are my core areas of expertise: • Embedded Linux & BSP: Custom firmware, kernel drivers, and deep optimization for SoC boards (Raspberry Pi, Orange Pi, NanoPi, etc.). I have extensive experience with Buildroot, Yocto, MAC-PHY communication, and precision timekeeping (PTPv2/IEEE 1588v2). • Networking & Telecom: 7+ years building 4G/LTE protocols (MAC-level, EPC, QoS). I regularly handle BGP routing issues, VPN implementations (IPsec/StrongSwan), and complex traffic convergence. • Edge AI & Computer Vision: Building optimized pipelines for video surveillance, real-time object tracking, and deploying AI models directly on edge devices. • Infrastructure & Email Systems: Advanced Postfix customization. I routinely design secure email obfuscation workflows, generate robust SPF/DKIM records for domains, and manage complex DevOps tasks like cloud migrations and remote work infrastructure. Zabbix and Grafana infrastructure monitoring, custom agents, alerting and visualization. Past Successes: • Led the full-lifecycle development of the MaxBridge 4G solution, successfully deployed across four countries. • Core BSP Engineer on the highly successful Carsifi project. • Rework old systems with new core elements, incorporating existing hardware protocols. I don't just write code; I solve system-wide problems. If you need someone who understands exactly how your hardware talks to your network, send me a message and let's discuss your project.
