Full-Stack Product Engineer (AI-Augmented) — shipping production-grade B2B SaaS at 3× speed 🚀
KM

About

High-velocity Product Engineer specializing in shipping production-grade B2B SaaS from zero to one. I leverage an AI-augmented workflow (Cursor, Claude, Copilot, V0) to deliver features 3× faster than standard development cycles — compressing 2-week sprints into 2 days without sacrificing architecture quality. Currently serving as the sole architect and primary engineer at SpeedMVPs, owning every layer from DB schema design to production UI. Built and launched AiLeadz — a live B2B platform with 250M+ verified contacts — as the single engineer behind all system-design and product decisions. Seeking to help early-stage founders ship their Zero to One products remotely.

Full-Stack Product Engineer (Core Team)
Sole architect and primary engineer for all high-complexity platform features — making system-design decisions, DB schema choices, and API contracts independently. Reduced feature delivery time by 60% through AI-augmented workflows (Cursor, Claude Dev, GitHub Copilot). Built and launched AiLeadz end-to-end — a B2B lead-gen SaaS with 250M+ verified contacts, AI-driven lead scoring, automated cold-email campaigns, and real-time analytics (featured on 47+ platforms, 4.9/5 rating). Engineered MaterialMate (M-Mate), an AI construction estimator integrating the Qwen2.5-VL vision model, a plumbing rules engine, and a PostgreSQL SKU matcher. Shipped MyClassGPT, an LLM-driven EdTech platform with a RAG pipeline serving contextual answers in under 1.5 seconds.
