A real data engineering problem: processing a massive CSV file that kept timing out a US tax engine. How I solved it in the browser, what I learned about chunk sizes, and why most tools get header handling wrong.
Real story: My e-commerce product images at rangmehal.shop were getting rejected by Instagram and loading slowly on mobile. I built this free image resizer with social media presets to fix it forever.
ToolLabHQ is a collection of free, browser-based productivity tools built and maintained by Abdul Wahab, a full-stack MERN developer and data engineer. Every tool on this platform was built to solve a real problem encountered while working on client projects, e-commerce operations, and data engineering tasks.
The CSV Splitter was built after a 500,000-row file kept crashing a US tax engine. The PDF Merger was created to combine shipping labels from an e-commerce store for electrical products. The CGPA Calculator was built because university students needed a free calculator that actually supports HEC grading. The ATS Resume Checker was built after watching people apply to dozens of jobs with no callbacks — not because they were unqualified, but because their resumes were missing keywords. The Plagiarism Checker was built after watching friends fail assignments due to accidental plagiarism. The Resume Builder was created to give job seekers a free alternative to expensive resume services. The Text Diff Comparator was built after an AI query nearly deleted critical database data. And the Slug Generator was built after product URLs like /product/1234532 on rangmehal.shop earned zero Google rankings — switching to keyword-based slugs fixed that overnight.
Every tool runs entirely in your browser. Nothing is ever uploaded to a server. There are no accounts, no subscriptions, and no hidden costs. The platform is supported through advertising — that is the only business model, kept honest and transparent.
