Solidity Developer

Onchain query latency was crippling analytical workflows (12-min wait times). Designed and built a blockchain-based data access layer with custom onchain indexing and optimized storage formats - slashed latency to 8 seconds. Existing full-refresh blockchain indexing couldn't keep up with transaction volume. Architected an incremental onchain data framework using CDC-based updates, cutting processing time by 94% and unlocking near-real-time digital asset monitoring. Sole owner of caching and data-availability architecture for a 4TB blockchain transaction dataset. Implemented Delta Lake with Liquid Clustering - eliminated 78% of redundant computation, saved 2,300 compute hours/month. Inherited a legacy digital identity platform with severe performance bottlenecks. Refactored cryptographic operations, rewrote concurrency handling, and modernized the stack end-to-end - reduced processing time by 95%. Owned blockchain node infrastructure cost from day one. Built automated compute-demand alignment across cloud workloads - delivered $420K annual savings.

Document verification had no immutability guarantees. Built the core notarization service with blockchain-based audit trails from scratch, re-architecting the backend to achieve 12x throughput for daily document processing. Designed and implemented a tamper-proof storage system for 28TB of notarized records using Merkle-tree integrity proofing and smart pruning logic - eliminated 95% of unnecessary data scans. Storage costs were unsustainable at 28TB. Introduced onchain/offchain hybrid lifecycle management with advanced compression - reduced footprint to 8.9TB (68% reduction) while preserving full cryptographic verifiability. Owned reporting pipeline end-to-end. Refactored query orchestration for legal document workflows - cut generation time from 45 minutes to 3 minutes.

Developed the financial-transaction processing service by re-architecting batch logic, adding safe parallel execution, and optimizing backend workflows - reducing the processing window from 6 hours to 55 minutes and improving system reliability for finance operations. Improved API and backend performance by tuning PostgreSQL at the application layer - introducing efficient indexing patterns, optimizing query structures, and refactoring slow endpoints - resulting in a 73% improvement in response times across high-traffic services. Delivered consistent product improvements by fixing software defects, enhancing backend features, and collaborating closely with product and QA teams - successfully completing 100+ engineering tickets and improving overall platform stability.
