Experience

Software Engineer Intern at Kaptured.ai (May 2026 — Present) — Building core modules for 1tap.video, an AI video-generation platform — a Remotion-based prompt-to-video component pipeline and a multi-tenant RAG chatbot widget. Integrated Stripe billing, led on-page SEO, redesigned the full site UI/UX, and built internal tooling (ads/Meta and LinkedIn crawlers for lead data).
Open Source Contributor at Braidpool · Bitcoin P2P Pool (Nov 2025 — Feb 2026) — Contributing to Braidpool, a Bitcoin P2P mining pool, in Rust. Built a unified CLI entry point for node RPC interaction (PR #333) and optimized Stratum v2 proxy performance by replacing global Mutexes with RwLock to cut lock contention (PR #405).
Full-Stack Software Engineer Intern at DartlineCargo · soniworldexpress.com (Jan 2026 — Jun 2026) — Designed and built soniworldexpress.com end-to-end — a production courier and cargo booking platform covering order creation, real-time tracking, and shipment management. Engineered a multi-courier rate-aggregator engine (a NimbusPost-style competitor) to compare carrier rates and automate shipment routing across logistics partners.

Projects

Fake-email — a web-based temporary email service that allows users to generate disposable email addresses for receiving emails instantly without registration (tags: Rust,Typescript,aws,Next.js) GitHub Live
Terminal Color — A lightweight terminal styling library for adding colors and formatting to CLI output, making logs and messages more readable and expressive. (tags: Rust) GitHub

Open source contributions

Braidpool — Braidpool CLI Implementation (Merged, PR 333). Adds JSON-RPC server for the Braidpool node with endpoints for querying braid data, mining info, peer management, and Bitcoin RPC proxying.
Braidpool — stratum: Use RwLock for connection_mapping to avoid blocking RPC (Merged, PR 405). Wrap connection_mapping in Arc<RwLock<ConnectionMapping>> so that getminerinfo and the Notifier use read locks, preventing Stratum from being blocked when miners are added/removed or when job notifications are sent.
Antiwork — Add: Vercel Deploy Button (Merged, PR 44). First Open Source Contribution
