StudyRaid

Gamified study platform: homework becomes quests with XP, levels, streaks, focus sessions and team challenges.

Every reward is computed on the server from an append-only ledger, and party challenges update live over WebSockets.

  • Python
  • FastAPI
  • Next.js
  • WebSockets
  • SQLAlchemy 2
  • Discord system

    NexusGuard

    Security and moderation bot for Discord servers that stops raids and spam, and explains every action it takes.

    Detection, rule and action engines run behind per-server safety caps, so a bad rule can't kick half the server.

    • Python
    • discord.py
    • FastAPI
    • SQLAlchemy
  • API & integrations

    DataBridge

    Connects an API or webhook to another API, maps the fields between them, and shows exactly which records failed.

    Retries only failures a retry can fix, with live run progress and credentials that never leave the server.

    • Python
    • FastAPI
    • httpx
    • asyncio
  • AI app

    ResolveAI

    AI support assistant that answers customer questions from your own help articles, with an embeddable chat widget.

    Answers cite the articles they come from; questions it can't answer are collected instead of guessed.

    • Python
    • FastAPI
    • SQLAlchemy
    • httpx
  • Automation platform

    NexaFlow

    Automation platform: a webhook starts a workflow that reshapes the data and notifies Discord, Telegram or any URL.

    A visual builder, templated steps and a readable log of every run, plus the product's marketing site.

What I build

Four kinds of work

  • Backend & APIs

    FastAPI services with authentication, roles, databases, API keys and third-party integrations.

    7 projects
  • Automation

    Background jobs, schedulers, webhooks and workflows that notify Discord, Telegram or any endpoint.

    7 projects
  • Full-stack apps

    Complete products: a Python backend with a React / Next.js frontend, designed down to the empty states.

    8 projects
  • Discord systems

    Bots, OAuth2 dashboards, moderation, onboarding and community tooling with real permission checks.

Engineering quality

Built beyond the happy path

  • Authentication & permissions

    Rotating sessions, OAuth2, ownership checks on every lookup. StudyRaid

  • Background jobs & retries

    Schedulers and retries only where a retry can change the outcome. DataBridge

  • Testing & CI

    Every repository ships a test suite that drives the real app, run on each push. StudyRaid

  • API integrations

    Field mapping, rate limits, signed webhooks and a record of every failure. DataBridge

  • Security-conscious design

    Hashed keys, encrypted secrets, SSRF guards, safety caps on automation. NexusGuard

  • Observable failures

    Runs, checks and actions keep the reason they failed, visible in the UI. ScoutFlow
