Denis Mokrinsky

Low-Code Engineer · Business & Systems Analyst

Full-cycle solutions — from business analysis through development to rollout. I analyse the process, design the data model and build products on low-code that I put into production and hand over to the team.

About

For me, automation is a tool for achieving business goals. I take responsibility not only for development, but also for making sure what I build becomes part of day-to-day operations and delivers high-quality, measurable results.

Low-code is my core professional domain. As CTO at Zerocoder, I led a low-code engineering team and owned not only my own solutions, but also standards, reviews and knowledge sharing. In fintech (Salmon / FHL), I joined the low-code team at the company’s earliest stage and built its first B2B products, helping the business launch faster.

I came into development from the business side: I studied logistics (BSc with honours from RANEPA) and ran international projects at Nestlé. This experience helps me understand business needs and turn them into working systems.

2018–2020 · EdTech · incl. MIIN

First role in tech after Nestlé: grew from technical specialist to CTO in about a year, building up development and no-code skills.
Owned the technical side of online-education projects (including MIIN, an institute of integrative nutrition); hired and led the team.

Demand & Supply Planner → Inter Market Supply Projects Specialist

Dec 2016 — Aug 2018 · FMCG · Moscow

Ran international supply-chain projects: adapting recipes to new markets (halal, UAE), launching sales on overseas marketplaces.
This is where I started automating: I taught myself VBA and wrote a script that saved about an hour a day for each of 14 colleagues. That’s how my path into development began.

Work projects

HR-tech · Zerocoder

Employee work tracking and payouts

A system for HR and team leads: reference data for departments, contributors, rates and work types. A manager records completed work, HR sees what is due and runs the payout. I designed the data model and the role structure, pulling scattered manual tracking into one transparent process.

Part of the company’s internal super-app — 250 users.

Low-codeData modelRole-based access

CTO · Zerocoder

Workload routing and balancing

Internal tool: incoming requests are distributed across the team automatically, weighted by each person’s current load. Removed manual routing and the imbalance where some people were swamped while others idled.

Part of the internal super-app — 250 users. More than 150,000 orders processed through the system.

Low-codeRouting rulesREST API

CTO · Zerocoder

Customer support automation

First-line ticket qualification and routing by department, automated answers to common questions and call-centre quality scoring built on transcription of every call.

First-line bots serve 1,500 students concurrently; quality monitoring processes around 40 hours of call recordings daily.

B2B admin panel: loan portfolio analytics

A panel for partner retail chains: analytics on loans issued at points of sale, plus post-lending servicing. Built the interface in Bubble and put a Hasura + GraphQL layer on top of an existing PostgreSQL, wiring front end and data together over APIs.

Mobile app: instalment payments and scoring

Customer-facing app for making instalment payments: a Bubble interface inside a mobile shell. Integrated an external scoring provider — the customer authorised on the provider’s side and the score came back into the product.

End-to-end analytics system

Brought customer touchpoint data from scattered sources into a single flow on Make. The business got the whole customer journey instead of disconnected per-channel fragments.

Internal tool for the sales team

A tool that assembles a customer profile from every touchpoint with the company: Bubble.io interface, data and logic on Directual. Sales got self-service access to the data without filing tickets to engineering.

Databaser interface: connection tabs, data grid and database schema graph

Databaser — database manager

A desktop client for working with databases: a SQL editor with schema-aware autocomplete, a virtualised result grid, query-plan visualisation as a graph and SSH tunnelling. Supports PostgreSQL, MySQL and SQLite.

SSH client with connection manager

A desktop client for working with remote servers: stores credentials, keeps every connection in one place and opens terminal sessions. My own take on Termius.

LLM proxy

A single entry point to language models: it exposes an OpenAI-compatible API, so any client or low-code scenario that already speaks OpenAI connects without rewriting the integration.

Over 1,000,000 requests served through the proxy.

I teach what I build. That includes n8n and Bubble — the tools I ship production automation with.

Media & speaking

I get invited to explain AI, neural networks and low-code — on national TV, in podcasts and at industry events. Translating complex things into plain language is a skill I practise in public.

Hobbies

What I do when I’m not building automation.

Editing video at two monitors in a home studio

Video production

I shoot and edit myself: light, sound, camera, final cut. That’s where the habit of explaining complex things briefly and visually comes from — in posts, product demos and course material.

Swimming & paddleboarding

Water is how I switch my head off. A paddleboard on the lakes near Moscow in summer, the pool all year round.

Table tennis

A fast game decided by reaction and precision. The best way to loosen up between blocks of work.

Squash

A dynamic sport where, after six months of regular training, I felt real progress for the first time.
