Roman Gafurov
Golang Engineer | High-Load Systems | Tech Lead

Go backends for high load.
Built to scale, tuned to save.

I make Go services carry millions of requests a day without falling over, and I lead the teams that keep them there. Ten years of backend work, most of it where traffic spikes are normal. Yerevan, remote worldwide.

Where I do my best work

If your project sits outside these domains, I'm probably not your best option, and I'll tell you so in the first five minutes.

Fintech & trading

Exchanges, wallets, payment flows. Latency is money, correctness is non-negotiable.

Travel & booking

Fare search, availability, checkout. Bursty traffic, huge fan-out, flaky third-party APIs.

High-load platforms

Marketplaces, SaaS, edtech at scale. Infra bills that grow slower than traffic.

Selected work

5s→1s
Dynatech — flight fare platform

Scaled search to 2M queries a day, then made it 3× faster.

HTTP → SQS migration, leaky-subscription fixes, and a rebuilt Go consumer cut time-to-first-result from 5 seconds to 1.

2M/day3× faster−66% log cost
Eurostar — booking platform

Cut the customer booking journey time fourfold.

Cache-aside plus deep memory optimization across login, checkout, and booking. Daily out-of-memory restarts gone for good.

YouHodler — crypto fintech

The backend behind 20× user growth.

Built and scaled core wallet and trading features as monthly active users grew twentyfold. Growth customers notice and the backend never lets them feel.

Interhome — vacation rentals

Ten times less traffic, none of the staleness.

Caching and request collapsing cut calls to partner systems by 4–10×. Availability stayed fresh enough that nobody downstream noticed.

How I work

  1. 01
    Measure before optimizing. Every number on this page started with a profile, a trace, or a bill.
  2. 02
    Boring tech, sharp execution. Proven tools pushed hard beat novel tools used timidly.
  3. 03
    Teams outlast code. Mentoring and honest reviews compound longer than any service.
