Sole developer of Paperpile's internal academic search platform, a 230M+ document system I own end to end (React/Next.js, Node/TypeScript, Python; MongoDB, Elasticsearch, PostgreSQL).

• Cut p99 search latency from ~10s to under 1s by redesigning indexing and query paths across Elasticsearch, MongoDB, and SQLite.
• Designed and maintained 10+ microservices handling millions of dynamic-payload messages, with strict retries, ordering, and idempotency.
• Built ingestion pipelines processing 300GB+ of text monthly, and raised corpus abstract coverage from 27% to 51% with crawler/scraper engines.
• Built the author-name parser (Stanford NLP model + a custom trie), reaching 87% accuracy vs 45-58% for the best open-source parsers at the time.
• Built an MCP (Model Context Protocol) server so LLM tools verify citations against the 230M+ corpus before emitting them, a hallucination-mitigation guardrail.
• Built AI plugins and a test-gated harness for the parser/crawler stack, cutting a release cycle from ~2 weeks to ~2 days.
• Own the shared middlewares and core utilities reused across the codebase, and ported legacy code to modern TypeScript for speed and memory gains.
• Cut production error rate from 10% to 2% and deploy time by 50% via CI/CD (Docker, Kubernetes); run ELK observability and own incident response.
• Built and own an internal data-management dashboard in React, plus Google Drive and OneDrive integrations and S3-backed storage.

Built the Content Management and Advertising module for ATM machines and cut ad initial-load latency from ~2 minutes to under 30 seconds on constrained, low-bandwidth hardware; root-caused a production defect blocking a major bank chain's ads.

I worked as full-stack developer with Seismic frontend, ServiceNow platform as backend. I started with design and analysis for a usecase, which eventully was developed as a prototype, then as a fully functional feature.

A team of interns was formed to build frontend for an e-Commerce site. I was the lead of interns team and also frontend developer to build UI for the site.
