ABOUT ME
I’m Kuldeep Singh, a Senior Full Stack Engineer based in Gurugram, India, with over 6 years of professional experience in designing and developing secure, scalable, and high-performance web systems.
My journey began at the National Brain Research Centre, where I contributed to cutting-edge neuroimaging projects for Alzheimer’s research — blending technology with science to advance healthcare innovation. Later, at SoftoBiz Technologies and now Easebuzz Pvt. Ltd., I’ve led software development initiatives that power large-scale fintech and enterprise platforms.
Throughout my career, I’ve combined deep backend expertise with strong leadership and problem-solving skills to deliver impactful, production-ready solutions. I take pride in architecting systems that are not only efficient but also robust, secure, and designed for scale.
Technical Expertise:
My expertise encompasses a wide range of tools, technologies, and programming languages:
- Programming Language: Python is at the heart of everything I build. From developing backend APIs to orchestrating asynchronous workflows, I leverage libraries like FastAPI, Django, Flask, Celery, Pandas, NumPy, SQLAlchemy, and Matplotlib to create elegant, efficient solutions.
- Front-end Development: I bring ideas to life through React, JavaScript, HTML, CSS, and Bootstrap, ensuring every interface is clean, responsive, and intuitive.
- Back-end Development: Proficient in Django, Django REST Framework, FastAPI, Flask, and Falcon, I specialize in creating reliable server-side architectures that deliver exceptional performance and security.
- Database Management: Experienced in PostgreSQL, MongoDB, and MySQL, with a focus on query optimization, schema design, and maintaining data integrity at scale.
- Cloud Services: I harness the power of AWS (Lambda, EC2, S3, CloudWatch) to deploy and scale applications efficiently, integrating Docker and CI/CD pipelines for smooth delivery and monitoring.
- Project Management: Skilled in Agile methodologies, Jira, and Azure DevOps, I ensure projects stay on track through structured execution, clear communication, and continuous collaboration.
What Drives Me
I’m passionate about engineering elegant solutions to complex challenges — whether it’s optimizing payment workflows, designing scalable APIs, or mentoring teams. My work philosophy revolves around excellence, innovation, and impact.
If you’re looking for a Full Stack Engineer who blends technical mastery with leadership and vision, let’s connect — I’m always excited to build something meaningful and transformative.
