AI Software Engineer

I ship AI products
to production.

Agents, RAG, automation, backend and turnkey DevOps — architected to be predictable, observable and hard to break. Comfortable in adult & grey-area niches where most won't go.

What I build

// 01 — 11
01

AI agents & assistants

For sites, Telegram, Discord: answer from a knowledge base, run multi-step dialogues, classify data, call APIs, trigger automations, return structured output.

02

RAG & AI search

Ingest, chunking, embeddings, pgvector, hybrid search, answers with source citations. Faster and cheaper than routing everything through an LLM.

03

LLM logic & agent chains

System prompts, structured output, JSON contracts, guardrails, state machines, LangGraph, multi-agent orchestration.

04

Predictable AI

Grounding, output validation, deterministic branches, fallback scenarios — fewer hallucinations, more trust.

05

AI observability & testing

Langfuse, token cost, latency, RAG tracing, run history, unit / smoke / QA scenarios.

06

Process automation

n8n, Make, REST, webhooks, queues, Telegram & Discord APIs, Notion — glue that runs your business while you sleep.

07

Full-stack products & MVPs

ASP.NET Core / Node.js / Python, React & Next.js, CRMs, portals, admin panels, dashboards, realtime, Telegram Mini Apps.

08

Turnkey DevOps

VPS / dedicated (incl. offshore), Docker, reverse proxy, SSL, CI/CD, monitoring, logging, backups, secrets. Infra you can run without a DevOps hire.

09

Crypto payment servers

Self-hosted SHKeeper & BTCPay — USDT/USDC & BTC, invoices, statuses, webhooks, automated payouts.

10

Generative visuals

ComfyUI / Stable Diffusion, Higgsfield — APIs, pipelines, job queues, delivering results into your product.

11

Audio & voice cloning

TTS and voice-clone systems, voice libraries, automated audio pipelines wired into bots and content workflows.
