Who we are

Most delivery problems are handover problems. DevGorithm owns architecture, design, frontend, backend and infrastructure together, so decisions made in the API show up correctly in the app, and what you launch is what you specified.

See how we work

We work with founders launching a first release, product organisations that need serious engineering capacity, and established businesses replacing software that has outgrown its original design.

  • Everything we build is yours — repositories, infrastructure accounts, pipelines and documentation in your name from day one, not held hostage to a maintenance contract.
  • You talk directly to the engineers writing the code, with a shared board you can read at any time and a straight answer when an estimate changes.
  • We write code to be maintained by someone else: typed, tested where it matters, reviewed, and documented well enough to hand over.

Soldout

Where live entertainment meets commerce.

A next-generation live commerce marketplace that brings sellers and buyers together through interactive livestreams, real-time auctions, social content and marketplace shopping. Sellers showcase products live while buyers watch, interact, bid, purchase, chat and discover — without leaving the experience.

Our role

Soldout was designed as a complete social-commerce ecosystem, combining the pull of live streaming with the convenience of a modern digital marketplace. Products surface through live shows, auctions, short-form video, seller profiles and conventional listings. The engineering centre of gravity is real-time interaction: live video, bidding activity, messaging and auction state are coordinated so the experience feels immediate. Behind the app sits a scalable backend covering marketplace operations, auctions, users, sellers, orders, payments, notifications, media and real-time communication — built out with separate deployment environments, automated testing workflows, infrastructure optimisation, monitoring, security hardening and performance testing.

Soldout demonstrates DevGorithm's ability to engineer a complex, real-time marketplace where mobile applications, livestreaming infrastructure, auctions, payments, backend services, cloud infrastructure and social-commerce experiences work together as one product.

How we work

Seven stages, each with a deliverable at the end of it. The point is not ceremony — it is making sure a wrong assumption costs a week rather than a quarter.

  1. Discovery

    We map what you are actually trying to change, who it affects, and which constraints are real. This is also where we tell you if a smaller build would get you the same outcome.

    • Problem and success definition
    • Constraint and risk register
    • Rough scope options with trade-offs

  2. Planning

    Scope is cut into deliverable slices with explicit assumptions attached, so when an estimate moves, you can see exactly which assumption broke.

    • Prioritised, sliced backlog
    • Estimate with stated assumptions
    • Milestone plan and review points

  3. Design & Architecture

    Interface and system design happen together. Data models, API contracts and screen states are agreed before implementation, because they are cheap to change now and expensive later.

    • Data model and API contract
    • Component and screen-state inventory
    • Architecture decision records

  4. Development

    Short iterations against a board you can read at any time. Every change is reviewed by a second engineer, and the main branch stays deployable.

    • Reviewed, typed, deployable increments
    • Working build available continuously
    • Written progress notes each iteration

  5. Testing

    Automated checks on the logic that would hurt if it broke, plus device, accessibility and localisation passes on real hardware rather than a simulator alone.

    • Automated tests on critical paths
    • Device and browser matrix results
    • Accessibility and localisation review

  6. Deployment

    Release is a pipeline, not an event: staged environments, automated checks, store submission handled, and a rollback path that has actually been tried.

    • Automated release pipeline
    • Store submission and approval
    • Verified rollback procedure

  7. Maintenance & Scaling

    After launch we watch the real numbers, fix what the monitoring actually flags, keep dependencies current, and scale the parts that measurement shows need it.

    • Monitoring and alerting in place
    • Scheduled dependency and security updates
    • Performance review against real usage
Why DevGorithm

Not slogans — commitments you can hold us to, and check in the code we hand over.

  • End-to-End Engineering

    Strategy, architecture, design, engineering, infrastructure and deployment handled together. No integration phase spent discovering that the app and the API disagree about what a user is, and no vendor pointing at another vendor when something breaks.

  • Architecture-First Thinking

    System boundaries, data models and API contracts are decided and written down before they become expensive to change — with the trade-offs recorded, so the reasoning survives the handover.

  • Transparent Communication

    A board you can read whenever you want, direct access to the engineers, and a straight answer when something slips — early, while it is still cheap to act on.

  • Real-Time Systems Expertise

    Live auctions, streaming, messaging and calling, where correctness depends on ordering, presence, reconnection and conflict. We have shipped this, not just read about it.

  • Production-Ready Development

    Separate environments, automated pipelines, monitoring, load testing and a rehearsed rollback path. Releases become routine instead of an event.

  • Long-Term Technical Support

    Agreed response times, deliberate dependency and security updates, and engineers who already know the codebase. Support does not mean waiting for someone to read your repository first.

  • Cross-Platform Expertise

    Mobile, web, backend, cloud and AI engineered together, so an architectural decision is made once with all of its consequences visible — and any defect can be traced from a tap in the app to the query behind it.

Client feedback

This section is built and ready. The quotes below are clearly-marked samples, kept in place until real clients have approved their own words.

These are placeholder quotes written to build and review this section. They are not statements from real clients, and none should be read as one. Each will be replaced with an approved quote, attributed by name and role.

  • Sample text
    Placeholder text, not a real client quote. This sample is written at a realistic length so the card layout, line wrapping and the balance between quote and attribution can be evaluated before genuine testimonials arrive.
    Awaiting client approvalFounder — sample placeholder
  • Sample text
    Placeholder text, not a real client quote. A second sample of a different length, so the grid can be checked for uneven card heights and for how a shorter quote sits against a longer one.
    Awaiting client approvalProduct lead — sample placeholder
  • Sample text
    Placeholder text, not a real client quote. A third sample, deliberately the longest of the three, to confirm that a detailed testimonial still fits the card without pushing the attribution out of alignment with its neighbours.
    Awaiting client approvalCTO — sample placeholder
