Altynbek Abdrakmanov

Nine years building and maintaining Rails applications, most of it as the backend owner on small teams where the work runs from data modeling through to production monitoring. Strongest on the unglamorous parts — query performance, background job pipelines, and third-party integrations that keep working past the happy path. I prefer established tools, and measure before optimizing.

Ruby on Rails Developer at DragonDrop.UK (2022-05 – 2026-06)

Custom ERP for a US home-remodeling contractor (Victory Home Remodeling)

• Owned backend development of the ERP end to end — data modeling, core modules, delivery — replacing manual operational workflows with automated ones.
• Cut response times 2–3× on the heaviest API endpoints by profiling in AppSignal first, then fixing what the traces actually showed: missing indexes and N+1 queries. Verified the gains in production rather than locally.
• Integrated third-party APIs with retry and error handling so upstream failures degraded gracefully rather than reaching users.

Ruby on Rails Developer at ScrumLaunch (2020-12 – 2022-05)

Agency work across several client codebases

• Shipped features and REST endpoints across several client codebases, with RSpec written alongside the code.
• Traced and removed N+1 bottlenecks in legacy Rails applications, measurably reducing response times.

Ruby on Rails Developer (contract) at Skincarisma (2020-04 – 2020-11)

Skincare product database, heavy on external data ingestion

• Migrated the Amazon Product Advertising API integration from v4 to v5 ahead of the v4 deprecation — zero downtime, no gap in product data.
• Designed Sidekiq pipelines that moved heavy data processing off the request cycle.
• Hardened the web-scraping module; better error handling and retry logic cut scraping failures roughly 3×.

Ruby on Rails Developer at Parts-Soft (2018-04 – 2020-03)

Auto-parts trading platform

• Built integration modules connecting the platform to auto-parts catalogs, payment gateways, and external web services.
• Added a task-manager module to the internal CRM for shared visibility into work in progress.
