Projects
Distributed Task Queue
Challenge: Scaling a task queue to reliably handle bursts and sustained loads of 1M+ tasks/day while avoiding head-of-line blocking and maintaining steady worker utilization.
Solution: Introduced partitioned queues, adaptive rate limiting, and prioritized batching; used a hybrid in-memory/Redis-backed index to reduce scheduling overhead and achieve 35% throughput improvement.
Ride-Hailing Matching Engine
Challenge: Scaling geospatial matching to support 10k+ concurrent events/sec with strict tail-latency SLAs under noisy location updates.
Solution: Optimized geospatial indices, sharded matching by region, and introduced a two-tier cache (Redis + local LRU) to cut lookup times and improve match quality by 60%.
Compliance Ledger
Challenge: Ensuring tamper-evident audit trails across microservices with minimal performance impact and simplified reconciliation.
Solution: Implemented append-only ledger segments with Merkle proof sampling and incremental checkpoints; replication and compaction kept storage overhead predictable while enabling fast proofs.
Drone Swarm System
Challenge: Coordinating low-latency state and commands across dozens of devices in intermittently connected networks.
Solution: Designed an optimistic state-sync protocol with conflict resolution and local fallback behaviors; added heartbeat-driven health-checks to maintain a 28% higher mission success in adverse conditions.
The Process
Discover the Essence
that drives your brand
I begin by clarifying your goals, audience, and market fit. The insights set a clear direction and define what success means for you.
Design Bold Ideas
with clear intention
I translate strategy into visual identity and page structure. Every element serves a purpose—clean, accessible, and ready for growth.
Deliver with Speed
and lasting impact
I build and launch your site in Framer or Webflow, then hand over an easy editor. You stay in control, with fast performance and room to scale.
ABOUT ME
I’m a designer and no-code developer creating bold, functional, and award- winning digital experiences that help brands connect with their audience.
