About

Who I am

Python backend engineer focused on async APIs, production systems, and reusable tooling.

I'm a self-taught Python engineer who went from first line of code to 5 deployed production systems and a published PyPI package in months. My focus is backend async APIs, database design, auth systems, and the infrastructure that keeps things running.

I care about writing code that's testable and maintainable. Before deploying Snip, I wrote a full integration test suite that surfaced 4 real production bugs. I published gatevault because I kept solving the same auth problem across projects and decided to package the solution properly.

Currently building Clustra a multi-org work management API with role-based access control at every layer. Open to roles where I can ship real systems with a focused team.

Focus Areas

Async APIs, PostgreSQL, auth systems, REST, Docker, CI/CD pipelines, open-source packages

Approach

Write tests before deploying. Wrap third-party exceptions. Ship then improve. Document what matters.

Currently

Building Clustra, applying to remote Python backend roles, and grinding LeetCode DSA patterns.

Open Source

Published on PyPI

Framework-agnostic Python auth library wired together so you don't have to.

📦 pip install richard-gatevault

gatevault

JWT token management, bcrypt hashing, OAuth2 login flow, and decorator-based route protection in one coherent package. Works with FastAPI, Flask, or plain Python. No framework assumptions.

  • JWT access + refresh tokens with expiry and tamper detection
  • bcrypt hashing with automatic salt management
  • OAuth2 flow - user lookup, verify, token pair generation
  • @gate.protected injects payload into any function
  • Clean exception hierarchy wrapping PyJWT internals
  • Full pytest suite · CI green · Automated PyPI releases

Deployed

Production Projects

Real systems running in production not tutorial clones.

snip-ly.xyz

Snip

Collision-safe URL shortener. Atomic counter encoded in Base62, every short code unique by construction, no UUID collisions, no retry loops. Fully async end-to-end.

Integration tests caught 4 production bugs before first deploy including a counter race condition only visible under concurrent load

Business Dashboard

Multi-tenant SaaS platform with row-level data isolation enforced at the ORM query layer. Blueprint factory architecture. Customer and order management for multiple independent users.

Per-tenant data isolation at the ORM layer, no user ever accesses another's records

devbrain.online

DevBrain

Developer knowledge base with tag-based multi-filtering, per-user content scoping, and full-text search. Blueprint modularization throughout. Multi-user auth with session management.

Tag-based filtering with per-user isolation, each user's knowledge base is fully private

Clustra

Multi-org work management API. GitHub-style hierarchy: Org → Team → Project → Task. Role-based access control at every layer. Labels, milestones, and activity logging.

RBAC hierarchy: Org Owner → Admin → Team Lead → Contributor → Viewer

Autopilot

Personal job application agent. Scrapes Ashby job boards across 60+ companies, filters by seniority and experience, generates role-specific application answers, and queues assisted browser submission via Playwright.

456 roles collected, filtered, and ranked automatically in a single run across 66 companies
