Freelance mobile app developer for Colombia: iOS and Android apps from one codebase. Planned for Law 1581 (Habeas Data), local payments and your time zone.
Cross-platform iOS and Android apps (Flutter or React Native) with secure APIs, push notifications, payments and app-store submission handled for you. Projects for Colombia run remotely with a fixed daily call window — 08:00–11:00 your time (18:30–21:30 IST). Scope, milestones and ownership are agreed in writing before work starts.
Projects for businesses in Colombia have to work for local customers and local rules. These points are planned from the first milestone:
Source: SIC — Ley 1581 de 2012
This is practical delivery guidance, not legal advice.
Colombia’s key sectors include start-ups & saas, it & software services, retail & d2c brands and tourism & travel.
Projects are planned for the market each business sells into. Cities covered in Colombia:
Colombia is on UTC−5. IST is 10 h 30 min ahead. There is little natural overlap, so a fixed call slot is agreed and work continues while you are offline. A daily call at 08:00–11:00 your time (18:30–21:30 IST) works year-round. Between calls you get written updates and a staging link that shows the latest build.
Map sign-in, roles, notifications, payments and device permissions. Decide how data synchronization handles interrupted connections. Prepare release assets and store-account access as separate dependencies.
These factors affect the work involved:
Share your budget in COP or USD. The schedule, payment milestones, external charges and support terms are agreed in writing before work starts.
Test the agreed device matrix, account recovery, permission denial, offline behavior and API errors. Store submission can be in scope; approval timing is decided by the store. Source-code and asset ownership, licences, account access and ongoing support are set out in the project terms.
Yes. Share your goals, timeline and budget and you receive clarifying questions or a scoped, milestone-based proposal. Work runs remotely, with written updates and a staging link you can review at any time.
It depends on number of unique screen templates, third-party SDK integrations (payments, maps), offline sync architecture and backend complexity. There are no fixed packages: share your budget in COP or USD and receive an itemised, milestone-based proposal.
The service catalog lists a typical range of 30 - 75 days; the real plan depends on scope, integrations and content readiness.
The build is planned around Law 1581 of 2012 (Habeas Data) and Decree 1377 of 2013: consent capture on forms, a clear privacy notice, data minimisation and suitable hosting. Larger companies must register their databases with the SIC’s national registry (RNBD). Final legal wording should be checked by your legal adviser.

Common options include PSE, Nequi, Daviplata, Wompi and PayU. Gateways are chosen around your customers, settlement currency (COP) and fees, and the full checkout is tested on mobile.
Calls run 08:00–11:00 your time (18:30–21:30 IST); everything else is asynchronous, with written updates.
