Jacek Mech – Leader | Manager | Builder

Professional Summary

Engineering leader with 25 years of experience building and scaling software systems, SaaS platforms, and engineering organizations of up to 50+ engineers. I specialize in scaling and restructuring teams to improve delivery speed, reliability, and organizational durability, with a background in multi-team leadership, leadership-layer design, people development, and cross-functional delivery.

I combine engineering leadership with hands-on technical judgment across architecture, system design, and complex problem solving in data-intensive and cloud-based platforms. My experience includes production reliability, platform engineering, distributed systems, technical decision-making, and translating complex technical work into executable plans across teams.

Over the past year, I have deepened my work in modern engineering practices through hands-on product building, platform engineering, and AI-assisted software delivery. I designed and validated a structured development approach connecting product definition, technical design, and implementation using coding agents and LLM-based tooling in a controlled, reviewable way. I have also built a geospatial AI agent that applies multi-step reasoning to location-specific analysis.

Professional Experience

Independent Product Architect & Engineer | GeoForm
Sep 2025 – Present

Impact: Used an independent hands-on build phase to deepen practical expertise in AI-assisted software delivery, agentic AI workflows, and modern platform engineering while designing and building GeoForm, a geospatial product serving as a proving ground for workflow design, coding-agent usage, and full-stack product implementation. In parallel, developed Shape, an artifact-driven workflow for controlled and reviewable AI-assisted delivery.

Key Highlights:

  • Developed Shape as a Structured AI-Assisted Delivery Workflow: Designed and refined an artifact-driven workflow connecting product definition, technical design, implementation planning, and execution into a controlled and reviewable model for AI-assisted software development. Validated that the method transfers across multiple coding agents and model setups.
  • Validated the Workflow Through Real Product Work: Applied Shape day to day while building GeoForm, using it across feature specification, task decomposition, implementation, and review in a live build environment rather than as a theoretical process concept.
  • Built a Geospatial AI Agent: Implemented a LangChain/LangGraph-based geospatial AI agent using OpenStreetMap data, POI category selection, tile-based metric calculation, and selected tile inspection to support multi-step reasoning over location-specific questions.
  • Built, Deployed, and Validated GeoForm in Real-World Scenarios: Delivered GeoForm end to end, deployed it on Hetzner and AWS, and used it in practical reporting contexts to validate the product and exercise the delivery workflow beyond internal prototyping.
  • Modernized CI/CD and Platform Operations: Migrated GeoForm delivery to a modern GitHub Actions, ArgoCD/GitOps, and Kubernetes/K3s-based CI/CD model, gaining current hands-on working knowledge of cloud-native deployment, release automation, cluster-based operations, and developer workflow improvements.

Technologies: JavaScript, TypeScript, React, Material UI, Node.js, Python, PostgreSQL, PostGIS, LangChain, LangGraph, GitHub Actions, ArgoCD, Kubernetes, AWS / Hetzner, Mapbox, GDAL, OpenStreetMap ecosystem, Codex, Claude Code, Gemini CLI, OpenCode.
