Leadership & Technical Experience
Leading engineering teams and architecting scalable systems across fintech, AI, and web3 domains. Focused on building high-performance solutions and mentoring the next generation of developers.
Engaged via Holdex as an engineering contractor for Truflation, an Austin-based company building TRUF.NETWORK — a decentralized platform for publishing, composing, and consuming economic data streams. Lead maintainer of kwil-db, the open-source distributed database (Go on PostgreSQL) powering the production system.
Backend services process 500K+ daily transactions on 50M-row PostgreSQL deployments, scaled 5x from a 100K baseline on commodity hardware via core algorithm and storage optimizations.
Lead Software Engineer
Promoted to lead engineering for TRUF.NETWORK, owning release engineering, performance, and architectural direction across kwil-db, the TRUF.NETWORK node, and three official SDKs.
- Open Source Leadership: Lead maintainer of kwil-db — shipped 27 production releases over 1,100+ commits, reviewing PRs from 30+ external contributors
- Storage Architecture: Designed a daily data digest / pruning architecture projected to achieve up to 96% storage reduction
- Cryptographic Verification: Designed an attestation layer producing tamper-evident, validator-signed query results for downstream consumers
- SDK Design: Maintain official Go, Python, and TypeScript SDKs with cross-language API parity; engineered transport abstractions for Chainlink CRE and third-party platform integrations
- Cost Optimization: ~20% AWS cost reduction across EC2/RDS/S3 while maintaining 100% SLA
- Async Collaboration: Operate across a 12-hour timezone gap with the US-based team
Backend Engineer
Joined as one of the early engineers building TRUF.NETWORK, a decentralized infrastructure for real-world asset metrics. Co-architected the backend services that became the production system.
- Throughput Scale-up: Drove a 5x scale-up from 100K to 500K+ daily transactions on commodity hardware
- Performance Optimization: Core algorithm and storage rewrites delivered 40% lower CPU usage and 40% reduced computation time
- Platform Development: Translated complex financial data modeling and Web3 integration patterns into production-grade Go services
- Business-Aware Engineering: Mapped technical solutions to concrete data-provider, consumer, and node-operator use cases
Contract work on coding-focused AI evaluation tasks across the two platforms — project mix varies by client and platform availability, spanning benchmark authoring, code migration evaluation, and structured model-output assessment.
AI Training Expert, Coding
- Evaluation Environments: Authored reproducible Docker environments and pytest frameworks with >85% line coverage for SWE-Bench style coding benchmarks across Python, Go, JavaScript, and TypeScript
- Cross-Language Migration: Developed end-to-end migration evaluation tasks (Python ↔ Go, Python ↔ TypeScript) with JUnit-based test parsers and agent evaluation harnesses
- Rubric Scoring: Performed structured rubric-based scoring and response ranking on multi-model LLM outputs with written justifications, surfacing failure modes like cross-language interop bugs and interface mismatches
Dealls is revolutionizing the job-seeking experience for professionals, and I was proud to be part of the team making it happen.
Intermediate Software Engineer
