I am an Application Developer and AI-native indie builder with 8+ years delivering enterprise software, cloud-native systems, integrations, and data-heavy workflows.

My CV spans Accenture, PDI Software, and Avenga: Sitecore eCommerce, WinForms and SPA products, .NET 6/8 services, Azure and GCP workloads, SQL performance work, identity integrations, GitOps, monitoring, and aviation data processing. Alongside that contract and consultant track, I build indie products and AI-native workflows with RAG, MCP, agents, evals, and modern model-assisted development—connecting software to real operational work.

Practice

Based in Bratislava, Slovakia. This site is a snapshot of the two tracks I run in parallel: contract/consultant application development and self-employed indie product building.

Engineering depth still matters. I build and harden .NET and cloud-native services (Web API, containers, IaC, SQL) and the integrations around them. My formal CV includes security, insurance, packaging, integration, and aviation domains, with work across business analysis, architecture, implementation, testing, deployment, monitoring, and production support.

Day to day I span coding, architecture, and digital workflows: model-assisted research and drafting, support and marketing acceleration where it fits, and automation (APIs, n8n/Zapier, agent hooks) so humans stay in the loop with auditability.

Track record

CV-backed delivery plus the indie track: Avenga contract/consultant work and self-employed product building from 2022 onward, grounded in earlier PDI Software and Accenture application development.

Tomas Kubinec · Self-employed

Entrepreneur · AI-native indie developer

EMEA · Remote

Show Details

Parallel indie track focused on product experiments, AI workflows, and practical automation, using the same software delivery discipline from enterprise projects.

Builds and validates self-employed product ideas around trust, knowledge systems, aviation-oriented workflows, and AI-enabled operations.
Uses model-assisted development, Cursor, Claude, Codex, MCP-style tools, and workflow automation to shorten research, build, and iteration loops.
Explores RAG, internal wikis, evals, guardrails, and agent workflows as practical product and operations capabilities rather than standalone demos.
Combines entrepreneurship, Microsoft development, DevOps, and full-stack delivery to move from idea validation to working software.

Indie products & experiments

The self-employed side of the work: product bets, internet-scale trust questions, and longer-horizon experiments I build and ship myself alongside contract delivery.

Founder Project · Trust Infrastructure

Decommissioned

The Carbon Club

Open Project Page

A proof-of-humanity initiative centered on a verifiable human registry, intended to create practical trust surfaces for the AI-native internet.

Built around a durable registry record anchored onchain as a time-stamped proof of issuance.
Designed to support downstream trust products such as bot filtering, Discord verification, and developer-facing verification APIs.
Presented as product infrastructure for environments where synthetic identity and impersonation are rising concerns.

Founder Project · Kids · Story & color

Decommissioned

Kidventor

Open Project Page

A web experience that captured what a child imagined, shaped it into a short storybook, and rendered companion pages as coloring adventures—until generalized image models and platform-native story modes collapsed the niche.

Turned free-form kid prompts into a coherent mini narrative with scenes parents could print or share.
Generated line-art and simplified shapes so the same story doubled as a coloring journey, not only a finished illustration.
Positioned for families who wanted structured, repeatable bedtime rituals rather than one-off pretty pictures.

In validation

A few parallel tracks in customer conversations—lightweight signals, not launch announcements.

DoctrieverValidation
Helps accountants collect missing client documents without the back-and-forth chase.
StoryTapValidation
Photograph any picture-book page and turn it into a tappable, talking demo—kids tap objects to hear names and play simple find-it games on books they already own.
WebPageCopilotValidation
Agent-orchestration experiment spanning lead discovery through delivery and maintenance—with minimal human nudging.

Focus areas

Architecture for AI speed

Systems stay maintainable and observable while AI-assisted delivery, iteration, and refactoring run at a much higher tempo—without sacrificing production discipline.

RAG that survives production

Retrieval design, chunking, hybrid search, and refresh pipelines so answers stay attributable to real sources—not one-off demos that collapse under messy enterprise data.

Knowledge systems, not toy chat

Internal wikis, runbooks, and policy corpora wired into LLMs with clear ownership and updates beat a standalone chat window nobody trusts after week two.

Faster product iteration

The edge goes to teams that prototype quickly, test demand early, and fold feedback into sharper product calls—especially when models and agents shorten the loop.

Human judgment over raw output

When execution gets cheaper, the work shifts to judgment: what to ship, how to measure it, and which ideas earn production-grade governance and cost controls.

Capabilities

Eight-plus years designing and delivering enterprise-grade software—plus hands-on AI-native building: retrieval and knowledge wiring, agent and MCP-style tool use, evals, and automation for research, ops, and product work.

Writing

Notes on AI implementation, architecture, retrieval and agents, and building systems that hold up in real organizations—not only slide-deck strategy.

Software Engineers Are Not Safe. They’re Early.

The real opportunity is not protecting the old engineering position. It is using today’s leverage to ship, test, and learn before the cost of building drops again.
