RevenosAI
RevenosAI required a high-performance distributed architecture capable of streaming high-cardinality lead batches through multi-step AI qualification without worker thread bottlenecks, memory exhaustion during spikes, or cross-tenant data leaks.
We designed a distributed queue worker cluster with isolated connection pools to prevent worker thread starvation. We built self-feeding lead batches, dual-tier database connection pooling, an ORM-level tenancy isolation layer, high-performance distributed caching cutting DB reads by ~95%, and an AI resilience engine with exponential backoff and jitter.
- Distributed async pipeline sustaining 5x worker concurrency on AI prospect enrichment
- Eliminated thread-blocking deadlocks by separating worker connection pools from queue producers
- ~95% reduction in database read queries on authenticated traffic via 300s Redis tenancy cache
- Zero cross-tenant data leaks enforced via schema-level tenancy plugin
- Fault-tolerant AI execution via exponential backoff and 30-minute automated human takeover snoozing
“Kryltex engineered our distributed async pipeline and multi-tenant AI execution architecture from day one. Their queue worker cluster, caching layer, and resilient AI execution engine allow our platform to process high-cardinality outbound pipelines with rock-solid stability.”
VPL Rewards
The manufacturer struggled with counterfeit physical paper coupons, high dealer friction, fraudulent concurrent QR scan attacks attempting code reuse, and complex factory logistics for generating print-ready batch stickers.

Brij Poshak Grah
During festive sales peaks and flash drops, concurrent checkouts caused inventory race conditions, deadlocked database writes, payment gateway socket hangs, and severe catalog latency degradation.
Engineered an Amazon-grade inventory reservation engine with dual stock counters (available vs. reserved) protected by 10-minute hold windows and multi-document ACID transactions in MongoDB. Decoupled an asynchronous background worker executing 60-second polling sweeps to detect expired orders and reclaim deadlocked units, built automated Razorpay payment failure rollbacks, implemented a 1-hour Redis category cache with event-driven invalidation, established multi-tier fail-fast socket timeouts, tuned a 10-socket connection pool across a 3-member replica set, and automated a Sharp WebP media pipeline.
- Eradicated inventory race conditions and overselling using 10-minute ACID hold windows
- Automated abandoned checkout stock reclamation via a decoupled 60-second worker sweep
- Reduced JSON serialization overhead and read payloads by up to 70% with .lean() projections
- Cut media bandwidth and storage footprints via automated 1200px WebP conversion at 80% quality
- Protected event loops from hung sockets with multi-tier timeout boundaries and a 30s graceful shutdown watchdog
“Kryltex solved our concurrency bottlenecks and checkout drop-offs completely. Their transactional inventory reservation and automated worker service handle our biggest flash sales flawlessly without a single oversold item.”
