Full-stack engineer • Bug bounty hunter • AI tinkerer

I design cinematic web moments that look like product launches, not student projects.

From realtime collab tools to security research, every build is treated like a flagship drop—fast, animated, and ruthlessly polished.

Storyline

I’m the guy re-building apps at 3 AM because the animation curve felt a little off. Shipping code is fun, but shipping an experience that feels alive is the whole point.

Fitness, gaming, and bug bounties feed the discipline—every reps set and every threat model review trains the same muscle: precision.

  • 2024

    Launched this unified studio site, merging blog, realtime apps, and auth flows under one glass interface.

  • 2023

    Disclosed multi-platform security bugs (Meta, Steam, JetBrains) with reproduction kits and mitigation docs.

  • 2022

    Built automation bots + AI experiments to streamline daily workflows for friends & clients.

  • Day 0

    Discovered code + gym + gaming trifecta — now it powers everything I create.

Proof of Impact

Security research + design polish = credibility. Every disclosure shipped with repro steps, risk mapping, and the “here’s how to fix it” deck.

Rank S

Instagram DM bypass

Non-followers could spam unrestricted DM threads—my exploit kit reproduced it reliably and unlocked a platform-level fix.

  • Exposed DM throttling flaw
  • Documented abuse pathways
  • Shipped mitigation notes
Rank A

Steam mobile session flaw

Showed that clones/restores preserved auth tokens, bypassing change-device locks and enabling higher fraud risk.

  • Full session replay kit
  • Impact: trade lock bypass
  • Proposed auth hardening
Rank B

JetBrains marketplace detail

Spotted outdated branding (pre-X Twitter assets) on a premium marketplace page. Small? Sure. But perception is everything.

  • Brand QA audit
  • Outlined asset lifecycle
  • Triggered refresh

Response time

Under 48 hours avg.

Teams respond faster when the report feels like a polished mini-site. That’s the bar.

Deliverables

  • Impact tables + GIF repros
  • Remediation roadmap
  • Follow-up verification
