Hello Visitor,
I'm Rahul Singh Shekhawat. A Cloud Engineer and Full-Stack Developer who genuinely enjoys turning ideas into real-world products.
My journey started with curiosity — understanding how applications work, how systems scale, and how technology can solve real problems. Over time, that curiosity evolved into building production-grade applications, cloud infrastructure, automation systems, and AI-powered tools.
I enjoy taking a concept from a simple idea on paper, designing the architecture, writing the code, deploying the infrastructure, and watching it become something people can actually use.
Core Interests
- Cloud Architecture
Designing scalable, secure, and reliable infrastructure. - Full-Stack Dev
Building end-to-end applications with robust backends. - Artificial Intelligence
Exploring AI systems, observability, and automation. - Product Dev
Transforming ideas into value-driven products.
What Drives Me
I enjoy solving complex challenges, learning new technologies, and continuously improving my craft.
Whether it's optimizing cloud infrastructure, designing architectures, or building monitoring platforms, I love the process of turning problems into solutions.
"Engineering is about understanding people, solving meaningful problems, and building technology that makes an impact."

AI & Emerging Tech
Selected Work.
A showcase of my recent projects, focusing on scalable architecture, AI integration, and sleek user experiences.
PulseGuard
A real-time monitoring platform for websites and servers featuring uptime tracking, DNS monitoring, SSL expiry alerts, and AI-driven insights for anomaly detection. Monitors 500+ endpoints with 99.9% check success and sub-second alert latency.
Observyze
An AI observability and monitoring platform focused on visibility, debugging, and trust in AI systems. Processes 2M+ reasoning traces/month, reducing LLM pipeline debugging cycles by 70%.
Env Secret Lock
A developer environment Secret Manager that solves the problem of secret sprawl. Secures secrets locally with zero-overhead AES-256-GCM. Active in production across 5+ engineering teams.
SubTrackHub
Analyzes cloud infrastructure usage to identify idle resources. Integrates LLMs to generate efficiency scores and recommendations, yielding an average AWS spend reduction of 35%.
VidVerbalize
Converts YouTube videos into short, captioned clips optimized for social media using AI-based transcription and automated highlight extraction.
NFT Showcase
A responsive NFT showcase website featuring curated collections. Hosted on AWS S3 with Route 53 domain routing for scalable delivery.
System Design Blueprint.
Interactive breakdowns of structural design decisions, cloud scaling models, cost efficiency boundaries, and deployment configurations.
Scaling Decisions
- Eliminated libuv thread lock contention on concurrent uptime queries by overriding standard DNS resolution with async UDP-based dns.resolve4.
- Scaled task polling clusters dynamically by deploying Fargate instances integrated with BullMQ queue size monitors.
- Engineered non-blocking raw socket connection queries for certificate and response monitoring to reduce thread footprint.
Cost Optimization
- Enabled Fargate spot pricing models, cutting active worker node costs by 70% in staging and dev environments.
- Integrated localized DNS and connection caching logic, reducing API requests and external lookups.
- Configured automatic TimescaleDB compression policies for raw records older than 7 days, maximizing storage capacity.
Monitoring Stack
- Tracks endpoint status (uptime, TLS configurations, SSL expiry warnings, response time).
- Applies a moving Z-score latency checker across historical check distributions to suppress noise and filter out network jitter.
- Integrates multi-channel notifications (Email, SMS, Slack, Discord webhook hooks) to warn developers of outages.
CI/CD Pipeline
- GitHub Workflows build multi-platform Docker container packages, pushing to AWS ECR.
- Triggers rolling blue-green container service rollouts on ECS via task definition updates.
