You will get a 30-min backend architecture review + written action plan
Project details
Bring me your biggest backend headache — latency, reliability,
scaling, or AI integration. I'll review your architecture and
deliver a written breakdown of exactly what to fix first. No
fluff, no upsell — just a clear diagnosis you can act on immediately.

About Danilo
Backend Engineer | Distributed Systems, AI Agents, Event-Driven | Node
Skopje, North Macedonia - 3:33 pm local time
Currently Senior Backend Engineer at Deel. Here's what that looks like in practice:
→ 95% API latency reduction (4s → <200ms) — found via Datadog, fixed via query profiling
and index optimization
→ 400,000+ invoices/month processed reliably — sharded pipeline with idempotent deduplication
and zero duplicate ingestion
→ MCP-integrated AI workflows replacing thousands of manual contractor uploads — 90% faster
→ 50,000+ active users scaled; $5K/month operating costs cut via e-commerce rebuild
You're in the right place if:
"I need backend engineers who own performance end-to-end, not just write endpoints"
"We're moving toward AI-native architecture and need someone who's already built it"
"Our system works until it doesn't — I want it to just work"
I work best with teams that:
✅ Have real infrastructure challenges, not greenfield toy problems
✅ Value observability and reliability alongside delivery speed
✅ Are building toward scale, not just MVP
Working together, you get:
★ Distributed systems designed for fault tolerance from day one
★ MCP and agentic integrations that make your existing backend 10x more capable
★ Performance investigations backed by real metrics — not guesswork
★ Code your team can maintain without me holding their hand
