Media Agencies — SaaS Developer

A senior saas developer for media agencies

Media agencies live or die on two things: buying well and proving it. Clients now expect every dollar of spend to be traceable to an outcome, and they expect the report before they ask for it. Meanwhile the buying itself has fragmented across programmatic, social, search, audio, and out-of-home, each with its own platform, its own pacing quirks, and its own definition of a conversion.

The operational cost is what quietly eats margin. Planners re-key insertion orders, account managers rebuild the same report in a different format for each client, and trafficking errors — a wrong creative, a missed flight date, a budget that paced too fast — surface only when the client spots them. Agencies that fix this plumbing keep clients longer than agencies that just buy cheaper.

A SaaS developer builds and scales software-as-a-service products for media agencies: multi-tenant applications, billing and onboarding flows, and the infrastructure that keeps them reliable as usage grows. The work is product engineering — architecture, tenancy, payments, and observability — built so the product can be sold, supported, and extended without a rewrite at the first hundred customers.

What you get

What this engagement covers for media agencies

  • Multi-tenant architecture — tenancy, permissions, and data isolation designed from the start, not retrofitted after the first enterprise customer asks.
  • Onboarding and billing — signup, trial, subscription, and payment flows that convert and that finance can reconcile.
  • API and integrations — public and partner APIs designed and documented, so your product connects to your customers' stacks.
  • Reliability and observability — monitoring, alerting, and error tracking that surface problems before customers report them.
  • Performance under growth — architecture and queries reviewed against real usage patterns, so growth does not become an outage.
  • Security fundamentals — authentication, authorisation, and data protection handled as part of architecture, not as a checklist at the end.
Working in Media Agencies

Built for how media agencies actually work

Tools and systems. Media work has its own established stack, and new builds have to plug into it. Buying and trafficking run through Mediaocean's Prisma for many agencies; audience and reach planning leans on Nielsen data and Comscore; reporting is assembled in AgencyAnalytics, Tableau, or Looker Studio; day-to-day coordination lives in Asana, Monday.com, or Slack; verification comes from DoubleVerify or Integral Ad Science. Any system that cannot read from and write to these tools will be ignored by the people doing the actual buying.

Where the work pays off. The work that moves the needle is operational: one intake for a campaign brief that flows into trafficking without re-typing; pacing alerts that flag overspend before the client does; a single reporting layer that pulls platform numbers into the client's own vocabulary; and a clean archive of plans, creatives, and results so the next brief starts from evidence instead of a blank document. Buying skill stays with the planners; the machinery around it stops leaking time and margin.

How it works

From kickoff to delivery

  1. Define the product scope

    Agree the smallest sellable product and the architecture it needs, resisting the everything-version.

  2. Build the core platform

    Tenancy, auth, billing, and the core workflows, with tests around the parts that must not break.

  3. Launch to early customers

    Controlled rollout with usage and error monitoring, and fast iteration on real feedback.

  4. Harden and scale

    Performance, security, and operational reviews as usage grows, before growth forces them.

Why Omer

Why hire Omer

  • Senior-only delivery: one person owns the saas developer work, its integrations, and its handover.
  • Built for production, not demos: permissions, monitoring, and documentation from day one.
  • Direct communication: no account-manager layer between you and the person doing the work.
  • Measured on outcomes: agreed metrics reviewed regularly, with scope adjusted on evidence.
  • No lock-in: your code, your data, your accounts, documented for handover.
FAQ

Questions, answered

Can you work with our existing buying and reporting stack?
Yes. Builds are designed around the tools already in place — Mediaocean Prisma for trafficking, AgencyAnalytics, Tableau, or Looker Studio for reporting, Nielsen and Comscore data for planning — so planners keep working the way they work, with less manual transfer between systems.
How do you handle client reporting without adding headcount?
By automating the assembly, not the judgement. Platform data is pulled on a schedule, mapped once to each client's definitions, and rendered into the report format they already receive. Account managers review and annotate instead of rebuilding spreadsheets.
What about pacing and trafficking errors?
Pacing checks run against flight dates and budgets automatically, and trafficking changes go through a single checklist with an audit trail: who changed what, when, and for which insertion order. Errors get caught before they reach a live campaign.
Can you rescue an existing SaaS product, or only build new ones?
Both. Rescue work starts with an architecture and code review that separates what is sound from what is holding the product back, and the plan follows that evidence — refactor, rebuild a module, or, occasionally, start over.
How do you handle billing and subscriptions?
Through established payment providers with proper trial, proration, and dunning handling, reconciled against your finance records. Billing is treated as product-critical code, with tests, because billing bugs cost trust fastest.
