Senior Software Engineer & Tech Lead

Wlad Radchenko startups coaching online

Software engineer and neural-network specialist with 5+ years building AI into B2C and B2B products and leading delivery on high-impact open source. I design and own systems end to end — backend services and APIs, desktop applications, and the models behind them — from architecture to deployment. My focus is generative and language models, applied ML and scalable backends in Python, React Native and JavaScript. Author of 20+ scientific publications, 9 registered programs patents, and research indexed in Scopus and Web of Science.

What I do

One engineer, the full stack of an AI product

I take products from idea to production — and I’m just as comfortable in a research notebook as on a deployment server.

Backend & Architecture

Scalable services and clean API design in Python, system architecture, traffic analysis, DevOps and server administration, VPN/networking and deployment.

Apps & Interfaces

Desktop applications, web, PWA and mobile apps with React Native, rich JavaScript interfaces, Telegram bots, AR/VR and games with neural agents.

Neural Networks & ML

Designing architectures and training generative, LLM and computer-vision models — including on-prem agentic “thinking” AI — from data pipelines to real-time inference in production.

Experience

Where I’ve built things

  1. Aug 2022 — Present, Saint Petersburg

    Senior Software Developer — VAS Experts

    Build fundamentally new neural-network solutions and ship them to production: an on-prem “thinking” search assistant over internal documentation and closed tasks, powered by a local LLM, with automated server diagnostics; and a deep-learning system that analyses network traffic to detect VPN signatures for blocking or policing — the basis of the third Scopus paper. Work spans LLMs, CNNs and computer vision.

  2. May 2024 — Present, Individual Entrepreneur

    Founder & Open-Source Maintainer

    Build and maintain open-source and commercial AI products with thousands of users — Wunjo Make (1.2k★) and the new Wunjo Design — integrating 50+ neural networks. Own the full lifecycle from architecture to deployment and support, with recognition in top weekly and monthly product rankings.

  3. 2021 — 2022, Anapa

    Software Developer — Freelance

    Delivered custom web applications and integrated neural networks for clients — including computer vision for a drone that recognises objects and estimates distance — with model training, data science and team management.

  4. Sep 2020 — Jul 2021, Saint Petersburg

    Developer RDP — Tricolor TV

    Applied machine learning to television-viewing behaviour — classifying subscribers by what they watch to inform which ads to show on TV.

Milestones in AI

How it unfolded

2026 — now

Wunjo Design

The newest product — a from-scratch PWA where neural models generate editable vector designs, not flat images or un-editable HTML.

Quart PWA LLM API

2024 — now

VAS Experts

An in-house, Gemini-style search over docs with AI Agents and tickets on a local LLM. I planned the architecture, procured hardware, wrote the API, cut LLM load, fine-tuned LoRA on our docs and trained from-scratch models that imitate our engineers — it reasons and asks clarifying questions, and I extended it to diagnose DPI servers from traffic logs.

LLM SmolVLM2 Qwen FastAPI Kafka LoRA AI Agentic

2023 — now

Wunjo Make

A neural-network suite that grew to a lot models as voice cloning, lip-sync, face swap, restyling, video generation. Open source (over 1.2k★) with a monetized commercial version (5k+ users).

GAN VLLM Briefcase Optimization

Open source

Berkano

A plant-analysis network trained in Python, then compressed from a 2 GB model to run via React Native (ONNX Runtime) on 2023-era phones — not just the newest ones.

Edge AI
Show earlier (2018 — 2023)

Spin-off

Drone swarm

On an experimental swarm project (successful enough to spin out a company) I built the drone’s brain on NVIDIA Jetson like object & face recognition with depth and distance estimation, fusing models to stay real-time without overloading the hardware.

Jetson Computer Vision Edge AI

2022 — 2024

VAS Experts

A new convolutional-network algorithm that classifies VPN vs. clean traffic from IPFIX behaviour.

CNN IPFIX Paper

Open source

Neural Radio & MOEX Portfolio

Infinite generated lo-fi radio (up to ~500 simultaneous listeners), written in Go with models trained in Python on a separate server and MOEX Portfolio over market data and comment sentiment to score a security’s rise/fall (it worked, but the edge was thin — an honest lesson in real-world ML).

Custom development

Camera systems that recognise faces and detect people’s presence and movement.

Computer Vision Face Detection

2020 — 2021

What colleagues say

Vladislav delivered neural-network solutions we’d considered out of reach — traffic analysis, computer vision and language models — and took them all the way to production. Dependable, hard-working and genuinely strong technically.

Alexey Alexeenko

CEO, VAS Experts

One of the clearest voices on applied AI in our community. Vladislav explains complex models simply and backs every idea with working code — a natural communicator and builder.
O

Oleg Ratunin

CEO, TenChat

A rare engineer who combines real research intelligence with the discipline to ship. Vladislav asks the right questions and turns them into systems that actually work.

Dr. Alexey Fedorov

Professor of RAAI, ITMO University

Curious, rigorous and self-driven. In our lab he introduced methods that were new to us and saw them through to results — a pleasure to supervise.
M

Dr. Michele Fiorentino

Professor of DMMM, Polytechnic University of Bari

Talented and tireless. His diploma work brought approaches that hadn’t been applied in production before, executed with unusual maturity for his level.
