You will get Complex SQLs built or Optimized
Project details
You will get precise, optimised SQL queries that extract exactly the data you need — fast, clean, and ready to use.
With 14+ years of experience working with enterprise databases across Oracle, MySQL, and SQL Server, I have written complex queries for Fortune 500 companies in supply chain, manufacturing, and logistics. I understand not just how to write SQL, but how business data is structured and what the output actually needs to accomplish.
What you can expect:
• Queries that are accurate, efficient, and well-commented
• Support for complex joins, subqueries, stored procedures, and performance tuning
• Clear explanation of logic so you understand what was built and why
• Fast turnaround with attention to your specific database environment
Whether you need a simple data extract or a complex multi-table reporting query, I deliver work that is production-ready and easy to maintain.
No guesswork. No back and forth. Just clean SQL that works.

About Nitish
Supply Chain Implementation Expert | EDI | TMS | ERP | Java | Python |
Pune, India - 11:04 am local time
I've been the person clients call when things get complex. When EDI integrations break, when UAT environments have critical gaps, when go-live is approaching and the data isn't clean — I'm the one who fixes it.
Here's what I actually do:
Supply Chain Implementation — end to end delivery across TMS, order management, vendor collaboration, and inventory optimization. I've taken projects from blueprint to production across multiple platforms and industries.
EDI Expertise — 300, 301, 304, 315 and beyond. Design, testing, troubleshooting, and vendor onboarding. If your EDI is broken or missing, I can find it and fix it.
ERP Integrations — Oracle, Microsoft AX, REST API, JSON mapping. I bridge the gap between platforms so data flows cleanly where it needs to go.
Technical Depth — Java, JavaScript, Python, Oracle SQL. I don't just consult — I can build, automate, and engineer solutions when needed.
Data Engineering — large scale CSV and JSON processing, data validation, cleansing, and transformation. I've processed millions of records across complex implementation projects.
Client Delivery — I manage stakeholders, run UAT, coordinate cross-functional teams across time zones, and communicate clearly at every level from developer to C-suite.
Industries I've delivered in:
Automotive | Industrial Manufacturing | Consumer Electronics | Logistics | Lock & Security
Why work with me?
Most consultants bring either business knowledge or technical depth. I bring both — which means I understand what the business needs, can design the right solution, and can actually build or configure it myself if needed.
I don't disappear when things get complicated. Complex is where I do my best work.
If you need someone who will own your problem, communicate clearly, and deliver — let's talk.
