About Vishal

Vishal R.Status: Offline
Full-Stack Engineer | Java & Python Specialist | Microservices | Kafka
Kathmandu, Nepal - 1:23 am local time
Are you dealing with a legacy system that struggles under load? Or building something new and want to make sure the architecture is solid from day one?

I'm a Senior Backend Engineer with 10+ years of experience building scalable, secure backend systems across fintech, logistics, education, and cybersecurity domains, with hands-on experience developing frontend applications using Angular, PHP, React, and Next.js for seamless full-stack solutions.

I specialize in designing clean architectures, building high-performance APIs, and solving complex backend problems — especially in systems where performance, security, and reliability matter.

What I Focus On

• Clean, maintainable, scalable backend architecture

• Designing the right architecture — whether modular monolith or microservices — based on business needs

• Secure authentication & authorization (OAuth2, JWT, RBAC)

• Event-driven systems using Kafka

• Efficient database schema design (PostgreSQL, MongoDB, DynamoDB, Oracle)

• Bridging backend systems with React, Next.js, Angular when needed

I don't just build endpoints — I design systems that stay maintainable as they grow.

Selected Project Experience

• Phishing Detection System: Processed millions of URLs daily to detect phishing and compromised credentials. Built with Python, Kafka, AWS Lambda, S3, and RDS MariaDB.

• Compromised Data Extraction System: Collected and cleaned stolen user data for threat intelligence teams, enabling organizations to detect active attacks. Implemented using Python, AWS Lambda, S3, DynamoDB, and Splunk.

• Phishing Analysis System: Analyzed thousands of phishing kits to identify attacker techniques and evasion methods. Built using Python, AWS Lambda, S3, PostgreSQL, Elasticsearch, and API Gateway.

• Online Education Platform: Backend development for a cloud-based learning system supporting real-time classes and coursework management. Built with Java Spring Boot, AWS S3, Amazon Cognito, and MongoDB.

• Online Course Enrollment System: Developed backend APIs with integrated local payment gateways (eSewa, IMEPay, Khalti) and secure notifications. Built with Java Spring Boot, React, Auth0, Amazon SES, and S3.

• TruckLoad Freight System: Designed a real-time freight marketplace backend enabling load discovery, bidding, and instant carrier offers. Built using Java Spring Boot, MongoDB, and Stripe.

• Mobile Banking Payment System & Android Apps: Developed secure backend services for transactions, wallet-to-wallet transfers, and real-time mobile integration. Built with Java Spring Framework and Oracle Database.

If you're looking for someone who understands backend architecture deeply and can turn complex requirements into clean, reliable systems, let's connect.

Note: I'm new on Upwork, so I don't have reviews yet. I’m offering a low introductory rate to help build trust and start collaborating on projects. Despite being new to the platform, I bring extensive real-world experience and am committed to delivering high-quality, reliable solutions from day one.

Steps for completing your project

After purchasing the project, send requirements so Vishal can start the project.

Delivery time starts when Vishal receives requirements from you.

Vishal works on your project following the steps below.

Revisions may occur after the delivery date.

Analysis & Backend Development

I review requirements, design architecture, set up project, configure the database, develop all APIs with JWT auth, OAuth2 (Google/Facebook), RBAC, JWT key rotation, middleware, push to your Git repo, show a local demo, and make changes if needed.

Review the work, release payment, and leave feedback to Vishal.
