About SigmaDev Digital
SigmaDev Digital builds and looks after the software businesses run on: websites, online stores, booking systems, customer and staff portals, mobile apps, custom business software, and the cloud hosting underneath them.
Who we are
SigmaDev Digital is run by Daniel Effiong, a software and cloud engineer based in Nigeria with six years of experience building and operating production systems. Daniel is an AWS Certified Solutions Architect and has worked across web, mobile, backend and DevOps, including on-call support for live systems.
We also build our own tools. Dartvel, our open-source framework for building apps, websites and servers from one codebase, is published publicly, and the free calculators and formatters on this site are ours too.
How we work
- You describe the problem in your own words; we tell you what would fix it.
- Nothing starts until you have a written scope and a fixed price.
- We build it, you check it, it goes live, and we train you to run it.
- We stay on afterwards with a monthly care plan, if you want one.
Who we work with
Small and growing businesses in Nigeria and abroad: hotels, event centres, restaurants, shops, clinics, schools, advertising and technology companies. We keep our clients’ names confidential; you can read what we did for them, by industry, on Our work.
