Project index · Verified repository work

Systems, products, and the decisions behind them.

I build backend-heavy software and applied AI products with explicit boundaries, testable behavior, and honest tradeoffs. These case studies focus on how the systems work—not inflated outcomes.

01 / Featured projects

Deep technical work.

Selected for architecture depth, reliability work, and relevance to backend and applied AI engineering roles.

01Reliable AI processing pipeline

Meeting intelligence · Team project

ScribeFlow

Meeting decisions disappear inside long recordings. ScribeFlow turns audio into searchable, evidence-linked transcripts, summaries, and action items.

  • TypeScript
  • React
  • Express
  • PostgreSQL
  • pgvector
  • Vitest
View case study GitHub Live demo ↗
Architecture illustrationScribeFlow
Verified repository flow: audio is uploaded to private Supabase Storage before the API coordinates transcription, structured analysis, persistence, and semantic indexing.
02Redis · consistent hashing · batching · fallback

Distributed systems · Full stack

Distributed Search Typeahead System

A Redis-backed typeahead system with consistent hashing, targeted cache invalidation, batched event writes, and graceful SQLite fallback.

  • Redis
  • Consistent hashing
  • Cache invalidation
  • Batching
  • SQLite fallback
  • Spring Boot
View case study GitHub
Architecture illustrationDistributed Search Typeahead System
Implemented read path: a debounced React query reaches Spring Boot, checks the responsible Redis node, falls back to SQLite on a miss or cache failure, and returns ranked suggestions.
03Safe, structured model integration

Applied AI · Legal technology

LexGuard

Contracts hide practical risk inside dense clauses. LexGuard structures those risks into consequences, obligations, and questions worth negotiating.

  • TypeScript
  • React
  • Express
  • Gemini
  • Vertex AI
  • Vite

Verified repository workflow: supported files or pasted text go to the Express analysis boundary, Gemini returns structured JSON, and server normalization prepares a predictable report stored for the browser session.

02 / Additional projects

Range, without filler.

Selected systems that broaden the story across networking, guarded AI generation, multi-tenant products, authenticated workflows, and retrieval research.
