Tech profile

Founder-CTO and hands-on backend engineer: 19+ years in software, 11+ of them building the infrastructure that travel distribution runs on.

Background

Nazmus Saaqeb Nayeem is a founder-CTO and hands-on backend engineer with more than nineteen years in software and more than eleven years building travel-distribution infrastructure: multi-source GDS, NDC and LCC aggregation, fare pricing engines, and B2B and B2C distribution platforms serving multiple international markets.

He leads a 70-person engineering and product organisation and remains an active contributor at code level — reviewing 37,000+ line service classes, diagnosing production defects from raw payloads and error logs, and shipping drop-in fixes against live supplier traffic.

He owns end-to-end architecture across a polyglot stack — PHP and MySQL, Go for latency-critical services, React for front ends and Redis for caching and coordination — with a delivery record of 35+ products and platforms across travel, pilgrimage logistics, travel accounting, messaging, e-signature, education and data intelligence.

Earlier leadership

Before the current role he served as Head of Department at a national payment gateway, CEO of a software services company, and Head of IT at an industrial group. See the experience timeline.

Architecture principles

Every change is verified against real supplier data before it reaches production.

01Canonical models over adapters everywhere
Every supplier is mapped into one internal contract at the edge, so pricing, caching and booking logic never branch on supplier.
02Deterministic, idempotent pipelines
Cache keys, booking retries and ticketing calls are designed to be repeatable without side effects.
03Measure before optimising
Cross-runtime benchmarks and byte-identical output checks come before any performance change.
04Evolve, don’t rewrite
Monoliths are hardened incrementally with targeted refactors and compatibility shims instead of risky big-bang migrations.
05Fail safe at the boundary
Sanitised client errors, correlation IDs for tracing, and no internal state leaked to API consumers.
06Ship operational tooling with features
Debug-trace panels, search consoles and payload inspectors are delivered as first-class tools for support and QA teams.
