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.

About Me

THE DEVELOPER
BEHIND THE CODE

I'm Soumik Mukherjee — a freelance software engineer and full-stack developer. I build the kind of systems I used to admire: secure, scalable, and elegantly designed. Available for hire worldwide.

My Story

BUILDING SOFTWARE
THAT MATTERS

Over 3+ years of engineering enterprise systems taught me something: most businesses don't just need code — they need a developer who understands the full picture. Architecture, design, infrastructure, security, deployment, and ongoing support.

That's why I work independently as a freelance full-stack developer. I'm not just a coder — I'm a problem solver who happens to write excellent code. Whether you need a freelance web developer, a freelance mobile app developer, or a freelance DevOps consultant, every project I take on gets the same level of care and attention.

My sweet spot is the intersection of robust backend engineering and beautiful frontend experiences, glued together with solid DevOps practices and infrastructure. I serve startups building MVPs, SMBs digitizing their operations, and enterprises modernizing legacy systems — all as a freelance software developer available worldwide.

Values

WHAT I STAND FOR

Security First

Every system I build is hardened from the ground up — authentication, authorization, encryption, and audit logging are non-negotiable.

Performance Driven

I optimize for speed at every layer — from database queries to API response times to frontend rendering. Milliseconds matter.

User Centred

Technology serves people. I design interfaces that feel intuitive and natural — because the best software is invisible.

Clean Code

I write code that other developers can read, maintain, and extend. Clean architecture, SOLID principles, and comprehensive testing.
