Built by a Real Developer
Solving Real Problems

Built after a 500,000-row CSV file kept crashing our tax-engine server at a US-based e-commerce client. Manually splitting the file took hours and introduced errors. This browser-based splitter solved it in seconds — and later helped process large Shopify invoice exports too.

Created for rangmehal.shop, an electrical-products e-commerce store. Shipping labels downloaded as separate PDFs for every order. Printing them one-by-one wasted 30+ minutes daily. The merger combined all labels into one file, cut that to around 5–10 minutes, and kept customer addresses off third-party servers.

Built for a US tax engine project that covered all 52 states and Washington DC. Off-the-shelf tax software started at $49/month — unacceptable for small sellers and open-source projects. This free tool supports five tax formulas and every US state, with zero subscription cost.

Designed for university students in Pakistan after noticing that most online calculators do not support the HEC (Higher Education Commission) grading scale. The tool calculates semester GPA, cumulative CGPA, converts marks to letter grades, and simulates relative (bell-curve) grading used by many engineering colleges.

Simple year subtraction gives the wrong answer for half the year. Legal documents, medical records, and school enrollment all require exact age down to the day. This calculator handles leap years, varying month lengths, and February 29 edge cases correctly — and also shows your next birthday countdown.

Team members on a role-based-access platform kept choosing passwords like "john123@" — crackable in seconds. This generator creates cryptographically random passwords of up to 64 characters with a live strength indicator, making strong passwords the path of least resistance.

A restaurant client lost online orders because customers mistyped the ordering URL. A QR code on every table eliminated typing entirely and helped increase online orders by around 35%. The generator supports URLs, WhatsApp, email, phone, and plain text with custom colors and logo embedding.

Sharing a phone number requires recipients to save it before messaging — a friction point that killed leads. wa.me links open a chat instantly, no contact saved. The generator covers 195+ countries with flag icons and supports pre-filled messages for e-commerce and client outreach.

Blog posts under 500 words rarely rank on Google. Students need exact word counts for assignment requirements. AI prompt writers need character counts for model limits. This real-time counter tracks words, characters (with and without spaces), sentences, paragraphs, and reading time — with no text length cap.

Developers constantly switch between camelCase (JavaScript), snake_case (Python), kebab-case (CSS), PascalCase (React components), and UPPER_SNAKE_CASE (environment variables). This tool converts between 10 formats in real time, with one-click copy for each — no more manual renaming.

Every social platform has different image dimension requirements — Instagram, Twitter, LinkedIn, YouTube thumbnails. Uploading oversized images to resize them on a server raises privacy concerns. This tool resizes JPG, PNG, and WebP images entirely in the browser with preset social-media dimensions built in.

Product photos at rangmehal.shop had messy workshop backgrounds. Client logos came as JPGs with white boxes around them. Every removal meant opening Photoshop and waiting. This AI-powered tool removes backgrounds entirely in your browser — no server upload, no subscription, results in seconds.

Built after watching people apply to dozens of jobs with no callbacks — not because they were unqualified, but because their resumes were missing the exact keywords recruiters' ATS systems scan for. Upload your resume and paste any job description to get your ATS score, missing keywords, and a full action plan instantly.

Professional resume services charge $50–$200 for something a developer can automate. This browser-based builder offers 6 templates, photo upload, drag-to-reorder sections, and one-click PDF export — all free, all private, with auto-save so no work is ever lost.

Recruiters and HR managers are now asking for portfolio links instead of resumes. Most portfolio builders charge monthly fees or require coding skills. This tool lets anyone create a professional web portfolio with 5 templates, skill bars, experience timeline, and a live public URL — free, no coding needed.

Built after watching friends lose marks on assignments because of accidental plagiarism — forgotten citations, phrases that matched textbooks without realising it. This tool checks essays and reports for repeated sentences, unusual phrase patterns, and AI-generated content signals, so students can catch issues before submission.

An AI-suggested database query nearly deleted critical production records because the change looked minor in plain text. After that incident, every code or content change gets compared line-by-line first. This tool highlights exactly what was added, removed, or modified — perfect for reviewing AI suggestions before applying them.

Content creators and educators needed character voices — a toddler narrating a story, a robot reading instructions, a grandpa telling a joke — without paying for expensive voice-over software. Voice Studio generates speech in 30+ unique character voices, transcribes audio in 15 languages, and translates between 24 languages, all in the browser.

My e-commerce stores rangmehal.shop and erinvault.com were generating product URLs like /product/1234532. Google had no idea what those pages were about — zero organic traffic. After switching to keyword-based slugs like /product/box-follower-hanging-with-filament-light, rankings improved significantly. This tool makes that process instant for everyone.

Built after seeing developers charge money for animated wish cards on TikTok while regular users kept begging for free access. Create birthday, Valentine, Eid, and anniversary wish cards with photos, music, animated themes, and a shareable link — completely free, no coding needed, no payment ever.
