Job Success
Berlin, Germany - 7:33 pm local time
With 5+ years in product engineering, I focus on high-performance, conversion-driven web platforms built with Next.js, React, and modern automation tools.
My work consistently delivers green Core Web Vitals, advanced technical SEO setups, and clean architectures that scale. The results show up in search rankings, conversion metrics, and real business outcomes — not just code.
I specialize in projects where UX, performance, and analytics must work together: marketing funnels, landing systems, internal tools, CRM integrations, and automation setups.

CORE EXPERTISE
• Next.js / React / TypeScript — performance-first architecture, reusable systems
• Supabase / Firebase / REST APIs — data workflows, automation logic, backend features
• Technical SEO — JSON-LD schema, sitemaps, metadata, Core Web Vitals optimization
• Analytics & Tracking — GTM, GA4, server-side tagging, conversion events
• CRM Systems — HubSpot, Bitrix24, Pipedrive integrations and lead routing

MY FOCUS
I don’t just code pages — I build systems that convert.

FEATURED WORK
LEAD LAB — AI Multi-Agent Growth Platform
Full architecture and development.
I designed and built LEAD LAB, a multi-agent AI platform for automated B2B lead generation, enrichment, email outreach, CRM orchestration, and strategic planning.
The system runs on a pnpm monorepo (Next.js 15, React 19, TypeScript, Prisma, PostgreSQL, Redis, background workers) with seven coordinated AI agents handling enrichment, strategy, campaigns, experiments, reporting, and orchestration.
Includes a custom admin dashboard, CRM core, compliance engine, A/B testing with bandit algorithms, multi-channel integrations (Brevo, Apify, IMAP, Telegram, WhatsApp, Instagram), and fully automated growth pipelines.
A production-grade, scalable architecture with 1,000+ code files, designed end-to-end.

MULTI-REGION PLATFORM — 3 Websites on One Scalable Codebase
I built a three-site platform for a development agency (Germany, Indonesia/Bali, Russia) on a single Next.js 15 / React 19 / TypeScript codebase.
Each site has unique positioning, SEO targeting, and content while sharing one architecture, design system, and component library.
Implemented 20+ service templates, case-study layouts, MDX content, hreflang, JSON-LD schemas, and consent-based analytics.
Core Web Vitals are green across all regions.
A high-performance, SEO-driven platform ready for global scaling.
⸻
DEVOPS PLATFORM — CI/CD, Kubernetes, CPQ Automation
I designed and built a three-site DevOps and engineering automation platform on a unified Next.js codebase.
Covers CI/CD pipelines (GitHub Actions), Kubernetes and infrastructure engineering, and industrial CPQ automation.
Strong focus on SEO architecture: keyword clusters, structured service pages, internal linking, clean metadata, and schema.
The platform targets technical B2B queries and consistently delivers green Core Web Vitals.
⸻
EVENTSTRIPE — High-Load Ticketing Platform
I engineered the frontend architecture and infrastructure for EventStripe, a ticketing platform built to handle extreme traffic spikes during event launches.
Delivered a high-performance Next.js frontend, CI/CD pipelines, Kubernetes deployment, autoscaling, observability (Grafana and ELK), and sub-120 ms response times.
The system handled 10,000+ concurrent sessions with zero downtime and real-time anomaly detection.
