About Roman
AI SaaS Developer | Laravel + React | LLM Integrations & Automation
100%
Job Success
Lviv, Ukraine - 2:49 pm local time
workflows that survive real users, real edge cases and real
error rates.
Most AI projects fail after the demo. The prompt works, then
the queue backs up, the API times out, costs triple, and there's
no audit trail of what the model actually did. I build the
infrastructure layer that makes AI features shippable:
background jobs, retries, streaming, cost control, human
review, logging.
100% Job Success. 5.0 stars on every contract. 400+ hours.
WHAT I BUILD
— LLM features inside real products: Anthropic (Claude) and
OpenAI APIs — structured output, function calling, RAG,
streaming responses, prompt versioning, token/cost control
— Document AI: parsing, extraction, classification and
validation pipelines. Built these for KYC/AML compliance,
where a wrong answer is a legal problem, not a bad UX.
— Vision & multimodal: image recognition workflows (OCR,
photo-to-structured-data), document scanning
— AI agents & automation: Telegram/Slack bots, autonomous
task runners with tool access, scheduled agent workflows
— The product around the AI: multi-tenant SaaS, subscription
billing, admin dashboards, role-based access, usage metering
STACK
Laravel 12, PHP 8.3, React + TypeScript, Inertia.js,
PostgreSQL, pgvector, Redis, queue workers, Laravel Horizon,
Node.js, Docker. Anthropic API, OpenAI API, Claude Code.
Production experience in Vue.js, Rails, Next.js.
SELECTED WORK
— Compliance platform (KYC/AML): multi-tenant system with
three identity-verification providers, automated document
generation, encrypted payload handling and e-signature
workflows. AI-assisted document processing on top of a
fully auditable pipeline.
— Autonomous dev agent: a Telegram bot wired to the Anthropic
API with server access — I send a task in chat, the agent
plans it, executes it and reports back. Built it because I
wanted to ship from my phone. It works.
— Finance SaaS (my own product, live): automated tax
calculations and reporting for sole proprietors, with
AI-assisted document handling.
— SaaS platform rebuild (5.0 rating): "Roman made a great job
to make our SaaS alive, he worked a lot on different part of
the code, front and back end."
I use AI-assisted development daily — which means I ship
faster than my hourly rate suggests, and I know exactly where
these tools break. That second part is what you're actually
hiring.
HOW I WORK
Written plan before code. Daily written progress. Clean,
tested, documented commits. Europe hours with US overlap.
I communicate in writing — Slack, Upwork, Loom, detailed PRs —
and I'm direct about scope and feasibility. If your AI idea
won't work reliably, I'll tell you before you fund it, not
after.
Send me what you're trying to automate and I'll tell you
whether an LLM is the right tool for it — plenty of times
it isn't.
