Hubs
Structured landing pages that connect tools, samples, and workflows around one theme.
Calculators, numerics, date logic, statistics, and finance tools
Image, audio, and video processing, conversion, and optimization tools
Color, layout, graphics, visual styling, and design helper tools
Writing, cleanup, formatting, extraction, and text analysis tools
Developer utilities, networking, web debugging, and automation helpers
Format, file, archive, unit, and encoding conversion tools
Match your resume against the actual posting to expose coverage gaps, score every bullet for strong verbs and quantified results, then rewrite the weak ones into STAR achievements with before-and-after evidence.
Turn raw hemocytometer square counts into cells per milliliter, compute trypan blue viability with live and dead concentrations, convert density between the dialects protocols actually use, and derive doubling time from two exponential-phase counts.
Map where speech lives in a finished recording, transcribe it into captions in the format the player expects, align caption timing to the speech, mix in audio description with program ducking, and prove the message survives degraded listening.
Fill one finished PDF form with a list of records to get a copy per recipient, mark the whole batch with a watermark, split merged output back into individual files, and compress everything into one delivery ZIP.
Diagnose why a CSV import keeps failing, map messy headers onto the target schema, remove duplicates under a stated policy, and emit typed INSERT statements or a bulk-load TSV.
Treat formulas as code with a full toolchain — build them from common functions and operators, evaluate them against real cell values with the references explained, expand and reverse-translate Excel 365 dynamic-array formulas like LET, LAMBDA, MAP, and REDUCE, and graduate anything repeated into a generated VBA macro.
Turn instrument readings into concentrations you can defend — convert between absorbance and transmittance, solve the Beer-Lambert law for whichever variable is missing, walk the nucleic acid chain from A260 to micrograms to nanomolar to copies per microliter, predict pH from strong acid and base concentrations, design buffers with Henderson-Hasselbalch, and check dissociation through molar conductivity.
Operate on JSON structure with a record of every cut — inventory the key paths before touching anything, address nodes precisely with RFC 6901 pointers or flexibly with JSONPath, rename keys by rule instead of by hand, apply RFC 6902 patches as an auditable operation sequence, and flatten to travel with a lossless way back.
Take messy tabular data to analysis-ready — merge source tables into one, strip the byte-order marks that break column matching, keep only the columns you need, fix spellings and formats, handle outliers by policy instead of panic, scale or standardize the numbers, and finish with range limits and a crosstab summary.
Furnish a bare spreadsheet into a workbook people can use without asking you questions — upgrade the legacy file, fill formulas down with the cells locked, name the ranges, gate inputs with validation dropdowns, let conditional formatting flag outliers, freeze the headers, build the index sheet, and set the workbook up to print.
Rescue a damaged PDF, strip what should not travel with it, and cut its weight — repair broken headers and cross-reference tables with diagnostics, export annotations before erasing them, remove metadata and form fields, then downsample and recompress to hit your size target.
Take any pile of PDF pages to a clean, printable document — straighten orientation and trim scan edges, delete or extract the pages that matter, unify every page to one paper size, choose color or grayscale for the printer, then add a cover and impose a booklet when the job is bound.
