Featured Projects

ktfo.gg — Fight Picks & Predictions
  • Built a full-stack MMA prediction platform with Go (Chi) backend, React Router v7/TypeScript frontend, PostgreSQL, and Redis
  • Designed multi-tenant platform architecture supporting independent organizations with configurable weight classes, titles, and events — with optimistic concurrency control across all aggregates
  • Designed multi-dimensional scoring engine supporting winner, method, round, and finish time predictions — with scorecard-based round-by-round adjudication from judge scorecards
  • Implemented all-or-nothing hardcore mode where a single missed dimension zeros the score, with crowd-percentage-based multipliers that reward unlikely picks — down to a 1% crowd share for maximum payout
  • Architected event-driven pipeline using transactional outbox with concurrent relay processing, batched stream publishing, and aggregate-based routing — with PostgreSQL LISTEN/NOTIFY as the primary trigger and a fallback polling interval for self-healing
  • Reduced scoring pipeline from 14s to 2–3s under 10k simulated concurrent users by replacing synchronous processing with parallelizable batch workers using Redis Streams and consumer groups
  • Built leaderboard system (global, per-event, per-org) using Redis sorted sets with batched writes and infinite scroll for full ranking visibility
  • Built comprehensive admin platform for managing organizations, fighters, events, fight cards, weigh-ins, results, and judge scorecards — powering the full lifecycle from event creation to final scoring
  • Implemented drag-and-drop bout reordering with debounced optimistic updates, intent-based action routing with exhaustive pattern matching, and conditional form logic for catchweight, championship, and cancellation states
  • Enforced end-to-end type safety with Zod schema validation on client and server, neverthrow Result types with exhaustive error handling, and safeFetch abstractions wrapping all API boundaries
A* and Friends — Pathfinding Visualizer
  • Built an interactive visualizer for A*, Dijkstra, BFS, and Greedy BFS using React, TypeScript, TailwindCSS, and Vitest
  • Implemented advanced config options: G/H weight sliders, heuristic toggles, diagonal movement with cost multipliers, and terrain-based weight presets
  • Developed a fully editable grid with cell-level weight editing, drag-to-paint controls, and start/goal/wall placement
  • Designed timeline playback modes (snapshot vs. granular) with state-synced animations for step-by-step debugging and exploration
  • Added visual overlays for visited/frontier/path states, including cost updates and stats to show the algorithm's decision making
  • Wrote comprehensive unit tests for core logic (A*, heap, path reconstruction, f-cost) using Vitest and automated CI via GitHub Actions
  • Engineered fallback goal handling when the initial goal is unreachable, including ghost path previews to simulate alternate paths

Experience

AlphaMap — Backend Engineer (Remote)
  • Developed an advanced data integration solution to unify multiple POI datasets, using string similarity algorithms along with geographic distance to improve data accuracy and consistency
  • Spearheaded a tenant finder recommendation engine utilizing the integrated POI dataset, significantly enhancing matching accuracy and optimizing tenant placement
  • Refined a large-scale corporate ownership dataset by conducting analytics, identifying and correcting bad entries, implementing NER tagging, and consolidating duplicate data
  • Engineered a robust ETL pipeline to extract data from a GraphQL API, implementing transformations and normalization into seven tables across datasets ranging from 140M to 1B entries
  • Implemented a comprehensive caching mechanism using Redis, enhancing data access speed and overall system performance across the entire application
  • Built a Redis-backed rate limiter with per-package keys and real-time usage tracking to optimize resource allocation
  • Contributed to the development of an enterprise API, focusing on scalability, security, and integration capabilities
