## Headline

Software Developer at Astrea \(Backend Focused Full Stack Dev\)

## About

I’m a backend\-focused software engineer who enjoys turning complex product requirements into systems that are reliable, predictable, and practical to operate\. Most of my work sits around backend architecture, distributed workflows, integrations and increasingly AI\-powered products\. I’ve built microservices, event\-driven pipelines, ETL systems, payment and fulfillment workflows, real\-time applications and AI features where correctness and data boundaries matter\. I’m particularly interested in the less glamorous parts of engineering \- idempotency, authorization, failure handling, consistency, retries, observability, and designing systems that behave well when things inevitably go wrong\. I also work with AI as an engineering tool, both inside products and in my own development workflow\. I’ve worked with RAG, vector search, context engineering, agentic workflows, OCR, and human\-in\-the\-loop guardrails, while using tools such as Claude, Codex, Cursor, and other AI\-assisted development workflows\. I see AI as a force multiplier, not a substitute for engineering judgment\. I still believe the engineer is responsible for understanding, reviewing, challenging, and sometimes rejecting the output\. What I bring is end\-to\-end ownership: understanding the requirement, shaping the architecture, building the system, integrating external services, deploying it and thinking through what happens in production\. Technologies I work with: Backend & Systems — Node\.js, TypeScript, Express\.js, Python, REST APIs, Microservices, Event\-Driven Architecture Data & Infrastructure — MongoDB, PostgreSQL, Prisma, Redis, RabbitMQ, Docker, AWS \(IAM, EC2, Lambda, S3, VPC\) AI Engineering — RAG, Prompt & Context Engineering, Agentic Workflows, Human\-in\-the\-Loop Systems Real\-Time & Frontend — Next\.js, React, WebSockets, Socket\.IO, WebRTC Integrations & Platforms — ETL Pipelines, Salesforce APIs, Razorpay, Stripe, Shiprocket DevOps & Observability — AWS, Nginx, Prometheus, Grafana, Sentry, Structured Logging I’ve also solved 1,500\+ DSA problems, which has given me a strong foundation for reasoning about algorithms, performance, and trade\-offs\.
