I design, build and ship web apps

I help individuals, startups, and small teams turn ideas into working products — web applications, automation tools, AI-powered workflows, and cloud-deployed systems. One s.p., one point of contact, full stack from interface to infrastructure.

Open to fixed-scope projects, retainers, and one-off consulting calls.

Services

One person.
The whole stack.

From the first prototype to the silicon it runs on — you work with one engineer who understands the whole picture.

01

Web Development

ReactNext.jsAPIsDashboards

Websites, dashboards, admin panels, frontend interfaces, React apps, backend APIs, and database-connected systems.

02

Programming & Automation

PythonBotsIntegrations

Python scripts, data processing, custom tools, Telegram/Discord bots, backend logic, system integrations, and workflow automation.

03

AI Solutions

LLMsRAGCloud APISelf-hosted

AI-powered tools, LLM-backed workflows, data extraction, content generation, RAG systems, and smart-assistant prototypes — cloud API or self-hosted.

04

On-prem Deployment

DockerCloudflare TunnelSelf-hostedHandover

Full-stack systems deployed to your own hardware or private server — Docker, Cloudflare Tunnel, and self-hosted AI configured and handed over ready to run.

How we work
(01)

Scope

We agree on the smallest version that proves the idea — a fixed scope, timeline anchor, and clear definition of done.

(02)

Build

I design and build it end-to-end — interface, backend, AI integration, cloud infra — with you in the loop, not behind a wall.

(03)

Ship

A working v1 you can test, demo, or pitch. Cloud-hosted or self-deployable, documented, and yours to keep.

(04)

Iterate

Refine based on real feedback. Fixed-scope follow-ups, a retainer, or a clean handoff — your call.

Why work with me

Three reasons people pick a one-person s.p. over an agency.

(01)

Cloud and on-prem in one engagement

Most freelancers are either cloud-only or self-hosting specialists. I cover both — build cloud-first, and if you need a private deployment, I hand it over fully configured. One invoice, one project owner.

(02)

MVP-focused, not perfection-focused

The goal is a working v1 that can be tested, demoed, or pitched — then iterated based on real feedback. I scope for the smallest version that proves the idea.

(03)

AI that fits your actual workflow

Not an AI wrapper bolted on. I wire LLMs into real data flows — existing databases, APIs, automation pipelines — via cloud API or a private instance you control.

Selected experience

Shipped, not slides.

Newsletter

Occasional notes from the stack.

A few times a year: new project writeups, cloud experiments, and the odd lesson learned. No spam, unsubscribe anytime.
