Selected work, told without the client names.

Many of our partners operate in competitive or sensitive fields and prefer to stay private. Each story describes the real problem, what we built and what changed.

TEL-01 Regional operator group
SDP Multi-country VAS

A service delivery platform between content vendors and mobile networks

Challenge

An operator group with networks in several countries needed one way to onboard content and service vendors, instead of separate integrations per network and per vendor.

What we built

A service delivery platform that connects vendors across the group's clusters to each operator: service provisioning, subscription and one-time billing, SMS flows and notifications, under the operators' regulatory rules.

How we worked

Cross-department workshops with the operators to define data inputs, end-to-end flow design for new value-added services, then deployment and validation inside the carrier environment.

TEL-02 National charity
SMS donations All carriers Public

Donations by text message on every mobile network in the country

Challenge

An official national donation platform wanted anyone with a phone to give in seconds, regardless of which operator they used.

What we built

A donation service integrated with all of the country's mobile network carriers, so a donor sends a short code and the amount is charged to their phone bill or balance.

Delivery

Design, operator integration and deployment, completed and certified for the charity.

Subscriptions Bilingual Reporting

Knowing exactly who is subscribed, billed and paying, every day

Challenge

Operator callbacks reported activations, first billing, renewals, failures and cancellations as separate events. Counting active, paying subscribers per day was guesswork.

What we built

A subscription engine that rebuilds each subscriber's lifecycle from callbacks and reports new, cancelled, active and charged users with revenue per day, per service and per operator.

Compliance

Offer pages generated from data, with operator-approved Arabic and English disclosures for subscriptions and one-time purchases.

One partner for every medical event on the calendar

Challenge

Healthcare organisers ran congresses and training days with a different supplier for the website, abstracts, payments, door control and filming. Data never matched and attendance was counted by hand.

What we built

A full event platform: a website per conference with speakers and programme, online abstract review, sponsor packages, paid registration, QR badges and scanners at every door, and Zoom for hybrid sessions.

After the event

Session recordings and speaker interviews edited into healthcare videos, plus attendance and revenue reports for sponsors and accreditation.

A checkout that speaks every carrier's language

Challenge

A content subscription brand sold mostly to mobile users in markets where few people pay by card. Each operator authorised payments differently, and users dropped off at the SMS step.

What we built

A single checkout that detects the country, lists only the operators that work there, and switches between direct billing, MT-MO and MO flows, opening the phone's message composer pre-filled in the user's language.

How it runs

Operator lists load from the database, so new markets go live without a deploy. Countries with no carrier fall back to email-based payment.

VPN Web-first New

Launching our own VPN with automatic account delivery

Challenge

We wanted a VPN we could sell through our own traffic and local payment channels. Off-the-shelf reseller storefronts could not handle our checkout, phone-number sign-up or server-side payment callbacks.

What we built

Our own storefront and account area with one-time and subscription plans, sign-up by email, phone or social login, and a central gateway that creates the VPN account the moment a payment clears.

Privacy by design

The network provider never sees a customer's real email or phone number. Each subscriber gets a generated identity, and expired accounts are suspended automatically every night.

Web + mobile Subscriptions EN / FR

A file-storage product with billing on every platform

Challenge

A consumer cloud-storage service needed to sell plans on the web, on iOS and on Android without three subscription systems disagreeing on who has paid.

What we built

One subscription layer fed by app-store webhooks, a web merchant of record and an embedded card form, all syncing to a single account. Social sign-in, resumable large uploads and multilingual pages.

Delivery

Run in sprints with a shared status board, plus the privacy policy and store-ready legal text the launch required.

OTT Licensing Investor model

Taking a niche streaming service from deck to launch plan

Challenge

A founder had a content licensing offer and an interested investor, but the deal terms, platform cost and pricing had never been tested against each other.

What we did

Reviewed the rights scope line by line, which surfaced a distribution limit that would have blocked the planned model. Scoped the API integration, re-encoding and DRM work on an existing platform.

Model

An interactive investor dashboard comparing one-time and subscription pricing, marketing scenarios and the daily sales needed for each profit milestone.

Landing pages that stay fresh and stay safe under load

Challenge

A streaming offer needed landing pages for paid traffic in premium markets. Creative fatigue was hurting click-through, and some traffic sources sent junk.

What we built

Fast-loading pages that rotate royalty-free backgrounds on every visit, carry every tracking parameter to a checkout built on the fly, and redirect from the server.

Control layer

IP rate limiting and per-affiliate and per-placement blocking, so a bad source can be cut in seconds from configuration.

Paying for the traffic that pays you back

Challenge

Affiliates were rewarded for every sale, including ones that later turned into refunds and chargebacks. Ad algorithms learned from the wrong buyers.

What we built

A server-side firing engine with three rules per source: every Nth sale, a target ratio that ramps up over the campaign, or a fallback. Duplicate orders never fire twice.

Insight

Net revenue by source, country and payment channel after fees, refunds and chargebacks, with alerts on sources whose sales go bad.

Finance Reconciliation Dashboards

From purchase orders to profit per month

Challenge

Revenue arrived weeks after the activity, net of processor share and bank fees, while affiliate costs were paid on a different calendar. Nobody could say quickly whether a month made money.

What we built

A pipeline that turns partner invoices and payment notices into structured records, and a dashboard showing billed, collected, fees, affiliate cost, profit and ROI by period, with each settlement proof one click away.

Insight

Trends and automatic commentary flag months where margins shift, so management sees the story without a spreadsheet.

One source of truth across regions and teams

Challenge

Payments, engagement and product data sat on separate servers in several regions. Teams built their own spreadsheets, and a basic question took three to five days to answer.

What we built

A star-schema warehouse fed by pipelines that normalise gateway responses, convert 15+ currencies and de-duplicate users, plus shared definitions for metrics such as active user.

Adoption

Workshops with finance, marketing, product and operations set five core use cases, from revenue reporting to gateway performance.

IT-01 Diplomatic mission
Managed IT Security Monthly reports

Keeping a diplomatic mission's office secure and online

Challenge

A foreign mission in Budapest needed dependable IT support where downtime and unmanaged devices are a security issue, not just an inconvenience.

What we do

Monthly on-site visits covering network and VLAN health, fingerprint access control, power backup, hardware inventory and user support, with call-outs between visits.

Reporting

Each visit ends with a formal report: asset register, risk findings ranked by severity, and clear recommendations for management.

Local SEO EN / HU Booking UX

Helping an independent professional get found and booked

Challenge

A senior stylist in Budapest relied on a third-party booking page with little search presence, and clients went to the wrong address on days he worked from a second location.

What we built

Bilingual English and Hungarian metadata, structured data for services, hours, location and FAQs, and social preview cards, injected into the existing booking template.

Detail

A script that, only when a client picks the day he works elsewhere, shows a bilingual notice with the correct location and a map link.

Compliance pages that brand themselves

Challenge

A group running many storefronts under different brands had to provide statutory withdrawal forms and policies on each one, and keeping copies in sync was error-prone.

What we built

One set of compliant pages that read the web address and load the right brand's logo and details on the server, so every storefront shows its own identity from a single source.

Result

Legal updates are made once and appear on every brand at the same time.
