AboutSummary
Backend engineer turned technical lead — 13+ years building, scaling and owning production systems, with team-leadership and lead/architect responsibilities since 2018. I design high-load distributed backends and I'm accountable for the architectural decisions behind them.
Plain version of what I do: requirements analysis and system design (I'd rather pick a fuzzy spec apart for an hour than ship a bug for a month), architecture trade-off decisions (monolith vs. microservices, relational SQL vs. column-store — I choose by load, not by trend), and the documentation, code review and testing discipline that keep systems alive for years.
Proof points
- Designed and scaled a multi-tenant CPA (cost-per-action / affiliate marketing) platform whose API peaked at 7,000 requests per second.
- A real-time statistics / analytics core I architected in 2016 is still running in production a decade later.
- Integrated four payment gateways end-to-end (payment processing / billing integration).
- Early adopter of ClickHouse for analytics; drove team-wide adoption of Vue.js and Docker.
- Led a backend team from 2018 — code review, mentoring, architectural sign-off, automated-testing rollout.
AI-augmented development as a default, not a novelty. I use Claude / Claude Code, ChatGPT, GitHub Copilot, Cursor and Codex daily, and I own the agentic harness end-to-end. I stress-test AI-assisted workflows in my solo indie game studio (nomorecare.gg), where I am sole architect, engineer and operator.
AI engineering with production backend experience underneath. I design agentic pipelines, own the harness around them, evaluate model behaviour, and turn AI-assisted workflows into repeatable engineering processes. My focus includes tool use, LLM fine-tuning, local models and human approval at the points where correctness matters.
I validate these patterns in my solo studio at nomorecare.gg: a web-novel design pipeline and a game-master pipeline, with the first version built on an agent framework. Engineering judgement remains the foundation: agents draft, systems validate, and the owner approves.
Core stack: PHP (5–8), Laravel, system design, microservices, distributed systems, AWS, ClickHouse, Terraform, Docker, Redis; relational and NoSQL databases (MySQL, MariaDB, PostgreSQL, ClickHouse, MongoDB, Couchbase, DynamoDB, OpenSearch).
Open to Tech Lead, Software Architect and Staff Engineer roles where trade-offs and decisions matter more than volume of code. Remote-first, based in Novi Sad, Serbia, on Belgrade time (CET/CEST, UTC+1/+2). Available B2B via a Georgian individual entrepreneur; also open to employment under Serbian labour law.

Senior Backend Engineer / Tech Lead at Quintegro Senior Backend Engineer / Tech Lead — Quintegro · Jul 2022 – Jun 2026 · Remote
Technical lead and senior backend engineer across confidential automotive analytics and marketplace products.
- As tech lead and senior backend engineer, designed from scratch the backend for a rare-vehicle market analytics service: processed 300,000+ historical sale records, produced aggregates across multiple market dimensions, and delivered date-aware currency conversion, watched-data alerts and request-history recommendations.
- On a confidential RV marketplace with 20,000 active listings, moved image processing out of the request path into background jobs, delivering a several-fold speed-up for multi-image upload workflows.
- Built a local development framework for a 43-microservice fleet, saving roughly 15–20 minutes on every validation iteration and removing contention around one shared dev environment used by four developers and two QA engineers.
- Implemented automated abuse controls that fully stopped a coordinated spam-registration campaign; also rewrote an in-house DynamoDB library from raw arrays into a query-builder API.
- Owned production releases and incident recovery across both products.
- Applied an Agents Framework, Claude Code and AI process automation to the working workflow: agents prepare drafts and implementation context, while the owner reviews and approves the result.

No More Care — Founder / Solo Engineer
nomorecare.gg →Solo (one-person) indie game studio with three roguelike games in development — sole owner of design, software architecture, code, infrastructure and release. Used as a real-world test bed for agentic AI / LLM-assisted (“AI-in-the-loop”) development workflows.
AI pet projects include a pipeline for designing web novels and a game-master pipeline for running structured tabletop scenarios; the first game-master version is built on an agent framework and is evaluated as an engineering workflow, not a toy prompt.
