I'm a hands-on Technical Lead and backend engineer with deep expertise in Rust, Substrate, Solana, and Zero-Knowledge Proofs (ZKPs). I build secure, scalable, and high-performance backend systems for decentralized applications, zk-integrated infrastructure, and real-time microservices. Recently, I’ve expanded into AI-aware project delivery, earning certifications in Prompt Engineering, GenAI Data Infrastructure, and CPMAI™ (Cognitive Project Management in AI). This enables me to design and execute systems that combine powerful backend architectures with modern LLM and AI-driven components. Throughout my career, I’ve delivered complex systems end-to-end — from designing modular, event-driven architectures to integrating blockchain protocols and building scalable data pipelines. I stay deeply involved in implementation, writing production-grade code using Rust, Actix-Web, Diesel ORM, Subxt, Kafka, and Redis. I thrive at the intersection of low-level performance, system design, and AI-aligned delivery—bringing structure, foresight, and precision to every project I lead. 🔧 What I bring to the table: Full backend systems in Rust (Actix-Web, Diesel, Tokio, Subxt) Blockchain integrations with Substrate, Solana, zkVMs, RISC Zero Real-time infrastructure with Redis and Apache Kafka AI-integrated project execution (Prompt Engineering, CPMAI™, GenAI Data Strategy) Strong experience with PostgreSQL, Docker, Kubernetes, and CI/CD pipelines Leadership in architecture, team mentoring, code reviews, and agile execution I'm open to roles such as Technical Architect, Engineering Lead, or CTO-track engagements where I can shape backend and AI strategy while continuing to write code, mentor teams, and deliver high-impact solutions.

At LiGo, I ranked 800+ keywords in 20 days, shipped 100+ high-quality articles, and built a content engine that feeds SEO, LinkedIn, and outbound - all from one source of truth. My stack: - Clay: automated LinkedIn workflows, lead enrichment, and account-based targeting - Phantombuster + Smartlead: multichannel sequences with deliverability dialed in - Webflow + Notion + Framer: fast landing page deployment - Reddit: early traction playbooks, meme-aware GTM - Product-led SEO: systematic scale, no burn What I do best: - Go-to-Market Execution: Positioning, messaging, distribution. Not strategy slides. - LinkedIn Growth Systems: Personal brands → attention → pipeline. - Landing Page Architecture: Copy that converts, SEO that compounds. - Acquisition Infrastructure: Email, social, SEO, community—all aligned. If you need someone who doesn’t just "advise" but builds, ships, and scales - let’s talk. And yes, I can vibe code. Pretty hard.
