I build backend systems that remain reliable under real-world conditions — not just ideal scenarios.
I specialize in Python backend development with a strong focus on building APIs capable of handling real-world constraints like abuse, edge cases, and high reliability. I believe in engineering for production from day one—incorporating observability, defensive programming, and clean architecture.
- 🏗️ Currently deepening knowledge in: Cloud infrastructure, Caching strategies (Redis), and Authentication (JWT/OAuth2)
- 🚀 Deploying production-ready systems on Koyeb, Vercel, and Render
- 🛡️ Passionate about security hardening and Anti-spam architectures
Core Focus:
- Languages / Frameworks: Python (3.11/3.12), FastAPI, Pydantic, SQLAlchemy, SQLModel
- Data & Caching: PostgreSQL, SQLite, Redis (Upstash)
- DevOps & Observability: Docker, GitHub Actions, Sentry, Prometheus
- Architecture: Clean Architecture, DDD Basics, Test-Driven Development (Pytest)
Not just a CRUD demo. A system built to simulate and survive real-world backend challenges.
| 🚀 Highlights | 🧠 Engineering Decisions |
|---|---|
| JSON-First Read Path for <50ms P95 latency | Read-heavy portfolio data bypasses the DB via in-memory cached JSON |
| Multi-Layer Anti-Abuse | 30-min Redis deduplication window + Honeypots + Silent Drop to frustrate attackers |
| HTTP Caching (ETags) | Zero-bandwidth revalidations with 304 Not Modified |
| Observability Stack | Integrated Sentry, Prometheus, and OpenTelemetry from day one |
| Quality Gates | Hard CI/CD enforcing >80% test coverage and strict linting |
Tech: FastAPI, Redis, PostgreSQL, Structlog, Slowapi, Docker, Actions
Payment engine strictly focused on deterministic financial calculations and clean boundaries.
| 🚀 Highlights | 🧠 Engineering Decisions |
|---|---|
| Deterministic Installments | Final payment absorbs any rounding drift to guarantee mathematically exact totals |
| Backend as Source of Truth | UI simply consumes the API; 100% of calculation rules isolated in pure Python domain logic |
| Framework Independence | Core rules are totally decoupled from SQLAlchemy/FastAPI |
| Explicit Rules | Handles Cash, Debit, Credit (2-6x 0% interest), Credit (12-24x 10% interest) |
Tech: FastAPI, PostgreSQL, SQLAlchemy, Pytest, React, TypeScript
