How long does a typical project take?

Timelines vary by scope. A small web app takes 4-8 weeks, a medium full-stack project 2-4 months, and enterprise-grade systems 4-8 months. As a freelance developer, I provide a detailed timeline during the Discovery phase and keep you updated at every sprint.

Do you work with startups or only enterprises?

I work with everyone — from early-stage startups building their MVP to established enterprises modernizing their systems. As a freelance developer, my flexible engagement models adapt to your needs and budget. I'm especially passionate about helping startups launch their first product.

What happens after the project is launched?

Every project includes post-launch support (duration depends on the scope). I handle bug fixes, monitoring, and minor updates. For ongoing needs, I offer freelance retainer packages and dedicated hourly/monthly arrangements.

How do you ensure code quality?

Every line of code goes through peer code reviews, automated testing (unit + integration), linting, and security scans. I follow clean architecture principles and industry best practices. As a freelance developer, my reputation depends on the quality I deliver.

Can you work with our existing team?

Absolutely. I offer staff augmentation, pair programming, and consulting models where I integrate directly with your team. I adapt to your tools, processes, and communication channels. Many clients hire me as a freelance extension of their in-house team.

What technologies do you use?

I specialize in Java, Spring Boot, React, Next.js, TypeScript, PostgreSQL, Redis, Docker, Kubernetes, and Kafka. But I choose technologies based on what's best for your specific project, not one-size-fits-all.

How do I hire you as a freelance developer?

Simply reach out via the contact form or email. We'll start with a free 30-minute consultation to understand your project. I'll then provide a detailed proposal with timeline, cost, and approach. You can hire me for fixed-price projects or on an hourly/monthly basis.

What are your freelance rates?

Every project is unique, so I provide custom quotes based on scope, complexity, and timeline. I offer competitive freelance rates for startups and businesses of all sizes. Contact me for a free estimate — no obligation.

Do you offer ongoing freelance support and maintenance?

Yes! I offer flexible freelance retainer packages for ongoing development, maintenance, monitoring, and feature additions. Many of my clients maintain long-term freelance relationships for continuous product evolution.

Do you sign Non-Disclosure Agreements (NDA) and transfer IP rights?

Yes, 100%. I sign a strict NDA before discussing sensitive project details. Upon full payment, 100% of the intellectual property (IP) rights, source code, design files, and deployment assets belong entirely to you.

FinTech Payment Processing Platform

Client: PayBridge Solutions

12,000+Concurrent Transactions

99.97%Uptime Achieved

98.5%Fraud Detection Rate

45msAverage Response Time

The Challenge

PayBridge needed a high-throughput payment processing system capable of handling 10,000+ concurrent transactions with 99.99% uptime, PCI-DSS compliance, and real-time fraud detection — all within a 4-month deadline.

The Solution

I designed a microservices architecture using Spring Boot with event-driven communication through Apache Kafka. The system featured JWT-based authentication, PostgreSQL for transaction logging, Redis for session caching, and Docker/Kubernetes for orchestration. A custom fraud detection module processed transactions in real-time using rule-based engines.

Key Features

Microservices architecture with event-driven Kafka messaging

JWT-based authentication and secure session management

Real-time fraud detection with rule-based scoring engines

PCI-DSS-aligned transaction logging in PostgreSQL

Redis session caching for sub-50ms response paths

Docker & Kubernetes orchestration with zero-downtime deploys

The Outcome

The platform sustained 12,000+ concurrent transactions with 99.97% uptime. The fraud detection module flagged high-risk transactions in real time, and the event-driven core scaled horizontally without a single payment outage across the four-month launch window.

Client Testimonial

“Soumik delivered a payment platform that handles our entire transaction volume flawlessly. The microservices architecture has been rock-solid, and the fraud detection module alone saved us millions.”
