Third-generation industrial supplies distributor here, based in Ohio, finally retiring paper pick lists. We need a native Android app that runs on the Zebra TC52 scanners our warehouse crew already carries.
The app needs barcode scanning tied to pick lists, quantity confirmation with over/short flags, offline queueing (our warehouse wifi has dead zones), and sync to our ERP through a REST layer an IT contractor is building in Node.js. Roughly 30 screens per the wireframes - nothing fancy visually, but it has to be fast and fat-finger-proof with gloves on.
Fixed scope, fixed price. A test device ships to you in week 1. Milestones every two weeks with payment on acceptance.

Spreadsheets run our warehouse today, and at 300 orders a day they are starting to fail us. We import specialty bike components from Taiwan and Italy and resell to dealers across the Nordics; the team needs one internal portal showing order status, shipment ETAs, and stock reservations instead of four Excel files that disagree with each other.
You would build a straightforward internal tool: authentication for about 15 staff, an orders list with filtering and search, a detail view with status history, CSV import from our forwarder's daily file, and simple role separation between warehouse and sales. Stack should be Next.js with Prisma over PostgreSQL - we host on a VPS and our part-time developer will maintain the tool afterward, so boring, readable code beats clever code.
We have wireframes (rough, in a Figma file) and a written spec of the data model. Fixed price, three milestones, and our operations lead is available daily on Slack for questions about how the warehouse actually works.

Our marketplace aggregates home improvement products from about 60 suppliers, and every supplier categorizes things differently - one vendor's "fixtures" is another's "bath hardware". We have 180k SKUs, roughly 40k of them hand-labeled into our 900-node category tree by our ops team over the past year, and we want a model that classifies the rest and handles new inbound feeds.
The work: explore the labeled data, pick an approach (we suspect fine-tuning a small transformer on title + description + supplier attributes will beat classic TF-IDF, but convince us with numbers), train it, and hand over a documented Python inference service plus a confidence-thresholded review queue design so low-certainty items route to humans. We measure success as >=92% top-1 accuracy on a held-out set our team curates.
Expect an async-first engagement. We will give you a sanitized data export on day one and access to a staging database. Weekly written progress updates matter more to us than meetings.

Our contract review platform sells to in-house legal teams at companies between 200 and 2,000 employees, and our current website copy was written by our CTO. It is accurate. It is also completely lifeless, and demo requests reflect that.
The engagement covers full copy for seven pages: homepage, two solution pages (one for GCs, one for legal ops), pricing, about, and two comparison pages against competitors we lose deals to. You will get recordings of eight sales calls, our win/loss notes, and access to our head of sales for a working session. We expect the copy to reflect how buyers actually talk about their problems, not how we talk about our features.
Deliverables in a shared doc with two revision rounds per page. Experience writing for B2B SaaS with a sales-led motion is required; legal industry experience is a nice bonus but not a dealbreaker.

Bluepeak Media is building a fitness MVP for a consumer brand client. The app tracks workouts, streaks and a simple social feed. We have full designs and a Firebase backend already set up by another contractor.
Scope for the MVP: onboarding, workout logging with templates, streak calendar, push notifications and the feed (read-only for v1). Both iOS and Android from one Flutter codebase.
We care about smooth animations and offline tolerance; gym basements have terrible reception. Store submission support is part of the final milestone.

A signed enterprise customer is forcing a problem we deferred for two years: our SaaS (HR onboarding tooling, ~200 SMB customers) has no real tenant isolation. Everything lives in one PostgreSQL database with a company_id column sprinkled inconsistently across 40-odd Prisma models, and at least three tables are missing it entirely.
The engagement is a schema audit, a written migration plan we can defend to the customer's security team, and then the migration itself: consistent tenant scoping, row-level security policies in Postgres, Prisma client middleware that makes cross-tenant queries impossible to write by accident, and a zero-downtime rollout. We have staging infrastructure that mirrors production and full freedom to rehearse there.
This needs someone who has done multi-tenant migrations before, not someone who wants to learn on our data. Ask us hard questions in the interview - we will do the same.

Enterprise buyers keep asking our sales team for proof, and right now the best we can send them is a slide with three logos on it. We provide managed detection and response for mid-market healthcare and finance companies, and we have customers willing to go on record - we have just never had anyone to do the writing.
The project is three case studies (interview the customer contact, draft at 800-1,000 words in a problem-solution-results structure, get their approval) and one 2,500-word whitepaper on ransomware readiness for mid-market healthcare, built from interviews with our two co-founders and research you conduct. We will handle design and layout; you deliver approved text with suggested pull quotes and callout stats.
Security is a jargon minefield, so we need someone who can be precise without drowning readers in acronyms. Interview scheduling runs through our marketing coordinator, and customers can be slow to review - patience with the approval loop is part of the job.

Engineers can smell marketing copy a mile away, and our blog is full of it. Hawkping makes uptime and API monitoring tools used mostly by backend developers at small teams; the blog gets decent traffic but trial signups from content are near zero.
The engagement: two articles per month, 1,500-2,500 words each, on topics like incident retrospectives, webhook reliability patterns, and status page best practices. You get an outline call with our CTO for each piece plus anonymized real incident data to make examples concrete. We handle publishing and distribution; you own research, drafting, and one revision round.
The ideal person has worked near production systems - a former developer, SRE, or support engineer who writes well. Long-term if the first two months click.

Over the past two years our freight tracking platform grew from one dashboard to eleven distinct modules, each designed by whoever was available that sprint. The result: four different button styles, three shades of "our" blue, and a frontend team that spends more time arguing about spacing than shipping features.
We need someone to build a proper design system in Figma - tokens, core components (tables, forms, filters, status badges, charts scaffolding), documentation for usage rules, and light/dark variants. Our frontend is React with Tailwind, so the token structure should map cleanly to Tailwind config; you will coordinate with our lead engineer on naming so design and code stay in sync. Expect to audit the existing modules first and propose consolidation before building anything.
This is a meaty project and we would rather do it right than fast. We are in CET but flexible; most communication happens in a shared Slack channel with the product trio.

Data & Analytics/Expert/12 days ago
Ops managers at the freight companies using our TMS keep asking for reporting we do not have, and exporting CSVs for them is eating our support team alive. We are FreightPath, a 12-person logistics SaaS, and we want embedded analytics built into our existing React app: on-time delivery trends, lane profitability, driver utilization, and carrier scorecards, all filterable by date range and customer.
The work splits into two halves. First, design the aggregate tables and materialized views in PostgreSQL so dashboard queries return in under two seconds against ~40M shipment rows. Second, build the dashboard views in React using our existing component library (we use Recharts already, no need to introduce anything new). We will provide designs for the first two dashboards; you will help shape the rest.
Our backend lead handles API plumbing, so you can stay focused on queries and UI. Code review turnaround is same-day. We would rather you ship one polished dashboard a week than four rough ones at the end.
