Backend-focused engineer who enjoys building clean, scalable, and secure systems
with a strong interest in system design, infrastructure intelligence, and real-world engineering.
- 🎓 Cybersecurity undergraduate
- 🧠 Backend-first full-stack developer
- 🔐 Interested in OSINT, domain & infrastructure intelligence
- 🛠️ Enjoys APIs, databases, queues, and system boundaries
- 🌱 Always learning by building real systems
I care less about hype and more about clarity, reliability, and good engineering decisions.
• Designing backend systems
• Thinking in trade-offs, not buzzwords
• Making systems observable & resilient
• Security-aware development
• Performance & scalability problems
Domain & Infrastructure Intelligence Platform
A cloud-native platform for collecting and analyzing domain, DNS, IP, and infrastructure signals, built with a strong emphasis on performance, scalability, and clean architecture.
Why it matters
- Asynchronous, queue-based scanning pipeline
- Redis-backed caching for high throughput
- Rate-limited & abuse-resistant APIs
- Designed with real-world constraints in mind
Core Capabilities
- DNS & extended DNS analysis
- ASN & hosting intelligence
- SPF / DKIM / DMARC validation
- SSL / TLS inspection
- IP reputation & proxy/VPN detection
Stack
- Node.js, TypeScript, Express
- PostgreSQL, Prisma, Redis
- BullMQ, background workers

| Area | Focus |
|---|---|
| APIs | Pagination, versioning, idempotency |
| Scalability | Stateless services, horizontal scale |
| Performance | Caching, async processing |
| Reliability | Graceful failure, isolation |
| Security | Rate limits, abuse prevention |
| Data | Indexing, query optimization |
| Observability | Logs, metrics |
- Better backend system design patterns
- Distributed systems fundamentals
- Containerized deployments
- Performance profiling
- Secure architectures
🧠 How I like to build systems
- Prefer simple designs that scale
- Measure before optimizing
- Expect failures and design for them
- Security should not be an afterthought
🛠️ What I want to get better at
- Large-scale system design
- Infra-level debugging
- Distributed data systems
- Long-running backend services
