Good COL Technologies · Founder
Dennis Portello
Solutions architect, product developer and AI-native engineer, with data architecture underneath all three.
Vancouver, Washington. Founder of Good COL Technologies and CTO of FR8Logik. Nearly three decades building data, AI and software platforms for startups and global enterprises, and the teams that run them.
What I do
Solutions architecture
I take a business problem to a running system: the architecture, the cloud footprint, the security posture and the roadmap, and I stay to build it. Recent work spans Kubernetes estates on AWS, GCP and Azure, Terraform with CodeBuild merge gates, and technology reviews written for partners and boards.
Product development
I ship products end to end: discovery, specification, build, release notes and support. In 2026 that included an operations hub for a digital agency, a Drupal site rebuilt as a Next.js application with an AI-first admin interface, and two desktop products of my own.
AI-native engineering
I build with agents and I build for them. My delivery practice runs multi-agent coding sessions for hours inside a budget, with guardrails, review lanes and evaluations. The systems I ship expose MCP interfaces with full admin parity, and when data cannot leave the building the models run on-premises or air-gapped.
Data architecture and engineering
Ingestion from SharePoint, email, EDI and S3 into a governed PostgreSQL warehouse. Calculation pipelines that replicate, then retire, spreadsheet logic. Drift gates on schemas and macros. Spark and Kafka at scale. I have built data platforms for logistics, solar energy, marketing analytics and SaaS.
Selected work, 2026
- FR8Logik Inventory Platform CTO, FR8Logik
- Replaced an Excel and VBA inventory workbook for a multi-brand beverage group with a four-layer platform: multi-source ingestion into PostgreSQL, a pandas calculation pipeline, a FastAPI service and a Next.js portal, running on EKS with Terraform, Graviton CI lanes and a CodeBuild merge gate. Live in production and operated daily.
- Motionstrand Fractional CTO
- Partner-level advisory with delivery behind it: an in-house operations hub with a Rust formula engine compiled to WebAssembly, Gantt, Kanban and permission-filtered search; a client's Drupal 10 site rebuilt as one Next.js application on EKS behind Cognito, CloudFront and WAF, with an MCP interface; AWS and Microsoft 365 governance; a password vault rollout; a quality engineering standard and CI/CD platform.
- Converseon Staff augmentation and tooling
- Senior engineers placed on the team since 2024, and an on-premises transcription and documentation pipeline where client audio never leaves the network.
- Own products Rust, Linux
- PatinaPDF, a Linux-native PDF tool with a patch-based write API, a JSON command line and an MCP server. b1edit, a GNOME code editor with a sandboxed agent harness, five model providers and an evaluation suite. Manduca, a documentation crawler with hybrid search exposed over MCP.
Experience
- FR8Logik LLCChief Technology Officer and Solutions Architect
Founder-led solutions practice for the logistics stack: architecture and roadmaps, pipeline migrations, production data platforms and dashboards, and AI that runs without third-party model providers.
- Good COL Technologies LLCFounder
Fractional and founding CTO engagements with a nearshore team across the Americas, built on a Colombian engineering network Dennis has been developing since 2008.

Migrated .NET, Java and Python services from Tanzu on vSphere to GKE Autopilot. Replatformed HPC workloads for a biotechnology company onto EKS and GKE. Moved Rust NLP models from Coreweave to AKS on GPU nodes for GDPR-compliant regional hosting.
- Assemblism LLC and BendR.ioCo-founder and Principal Cloud Architect
Founded BendR.io, a low-code visual ETL and business intelligence platform on Apache Spark and Kubernetes across AWS, GCP and Azure, with on-demand Spark clusters starting in under 15 seconds. Through Assemblismo, delivered CTO-level advisory and software for 80 Acres, Converseon, Rappi and Muncher, and led a team of about 25 engineers, product managers and designers in the United States and Latin America.
- Cypress Creek RenewablesSVP, Cloud and Data Platform Engineering
Stabilized nationwide solar telemetry pipelines, designed the S3 and Redshift data architecture, moved a Node.js monolith to microservices on Kubernetes, and scaled battery optimization models to distributed PySpark, while the company grew from one employee to more than 900 and past 1 GW deployed.
