Hello, I am interested in the Backend Developer role and have strong experience building and maintaining production backend systems using Python and Java with AWS cloud infrastructure. I have worked extensively with PostgreSQL and relational databases, REST APIs, backend service architecture, debugging production issues, and performing root cause analysis in live environments. My experience includes deploying and managing applications on AWS services such as EC2, S3, Lambda, RDS, IAM, and API Gateway, along with implementing CI/CD pipelines, Docker-based deployments, and monitoring for reliable system performance. I am comfortable working in structured SDLC environments, collaborating with tech leads on solution design, and supporting critical production systems with strong focus on stability, security, and performance.

Your production environment will fail during peak traffic if your PostgreSQL RDS instance isn't configured with read replicas and connection pooling. I've debugged similar bottlenecks for 3 clients where a single database instance caused 5-second query delays that crashed checkout flows. Before architecting the solution, I need clarity on two things - what's your current RDS instance size and are you handling more than 500 concurrent connections? Also, do you have any compliance requirements like SOC2 or ISO that'll affect how we structure AWS IAM policies? Here's the architectural approach: - PYTHON + JAVA: I'll build microservices that handle async processing through SQS queues, preventing timeout failures during high-load periods and reducing API response times to under 300ms. - POSTGRESQL RDS: Implement query optimization with proper indexing, connection pooling via PgBouncer, and read replicas to distribute load - I've scaled similar setups from 200 to 5K queries per second. - AWS LAMBDA + EC2: Design event-driven workflows that auto-scale during traffic spikes while keeping EC2 instances for stateful services, cutting infrastructure costs by 35%. - DOCKER + CI/CD: Set up GitLab pipelines with automated testing and blue-green deployments to eliminate downtime during releases. I've spent 12+ years managing production systems that process millions of transactions daily. I don't take on projects where monitoring and alerting aren't properly configured - let's discuss your current observability stack and failure scenarios before we start building.

I have strong experience in backend system development, AWS infrastructure management, production support, and debugging scalable applications using Python, Java, PostgreSQL, and cloud-based architectures. I have worked on production-grade backend systems involving API development, database optimization, AWS deployment, issue resolution, and system monitoring with a strong focus on stability, security, and performance. I’m also experienced with Docker, CI/CD workflows, Linux environments, and handling critical production support scenarios. Comfortable working in overlapping IST shifts, collaborating with technical teams, and following structured SDLC and deployment processes for long-term enterprise projects. Available for discussion and can share my detailed profile, relevant project experience, and availability immediately.

Hi! I saw your need for someone strong in Python or Java on AWS for backend support and production fixes. My main stack is Node.js, GoLang, and PHP — not Python or Java. But I have handled similar AWS deployments and production support, building multi-region SaaS platforms with PostgreSQL and AWS services like EC2, S3, RDS, and Lambda. If you are open to Node.js, I can cover the same backend work, including database tuning, root cause analysis, and compliance checks. My approach is usually quick diagnosis, followed by clear documentation, so handovers are smooth. Does your setup allow for parts of the backend to run in Node.js, or is Python/Java a hard requirement? That will tell me if I’m a real fit. Happy to share a short outline of how I’d support production, free. You can see projects using this flow at work.techindika.com. — Pradeep

I can support this Backend Developer role and handle production systems, backend services, and AWS based deployments and I can start right away. This looks like a role where stability and debugging matter a lot because most of the work is keeping production healthy and quickly fixing issues when things break. I would work on Python and Java backend services, manage PostgreSQL databases, and handle AWS services like EC2 S3 and Lambda with a focus on clean deployments and fast RCA. I also keep things practical with monitoring and simple CI/CD so issues are easier to trace instead of becoming long overnight fire drills. I have 8 years of experience in Python Java and AWS and I am waiting for a response.
