Engagement

Through TechnoNext Software Ltd. (concern of US-Bangla Airlines) as Software Engineer, April 2024 – present. TakeOff runs on the shared multi-tenant OTA platform I work on; I am listed as a developer on the TakeOff project.

What I Did

  • Built and maintained the shared multi-tenant OTA platform (B2B & B2C) this brand runs on — part of a 36+ service ecosystem serving 6 OTA clients.
  • Delivered 8 cloud-native supplier integrations (Sabre, Travelport, Travelport NDC, Air India, Flydubai, SQ NDC, TK NDC, IndiGo), increasing flight search feed by 27%.
  • Implemented Progressive Search, Search Ranking, Universal Split PNR, Refund Reissue and PNR Details.
  • Built the Booking Cancellation Service (ASP.NET Core + Hangfire) that cancels un-ticketed bookings before the last ticketing time.
  • Built an xUnit API integration test suite for 30+ supplier integrations, and integrated APM with Elasticsearch structured logging.

Impact

  • ADM penalties reduced by $4,500–$6,400 per month per OTA (~$23K–$27K saved across 6 clients).
  • Production failure rate cut by 30% after APM + structured logging.
  • Flight search feed up 27% from new supplier integrations.

Proof of Work

How a Redis Stampede (Thundering Herd) Hit Our OTA Search Ranking Engine — And How We Fixed It

When 30 integrated suppliers and 40-50 unique airlines per search met an uncached rank lookup, concurrent cache misses stampeded the database in unison — here's how negative caching and locking around retrieval broke the herd.

Progressive Search: Showing Flight Results Before All 30 Suppliers Answer
