Web, mobile, design & modernization
Four ways we ship software
Pick the path that removes the biggest risk first — then deepen after a measurable milestone.
Software development services in Dar es Salaam, Tanzania
Web platforms, mobile apps, UX/UI design and system modernization, built by one accountable team that understands Tanzanian workflows and mobile money. Assisted Engineering means agents accelerate delivery; our engineers own architecture, review, and what ships.

Software we design and deliver across healthcare, microfinance, education, and operations in East Africa.
End-to-end microfinance LMS — KYC, group & individual loans, disbursement, collections, CRB-ready.

View solution →SSO-style microservices platform for unified hospital system access.
View solution →“We needed software that matched how our teams actually work — not a template. Delivery stayed clear week to week, and we own the code.”

Figures are indicative starting points. Final pricing depends on scope, timeline, and integrations such as mobile money or legacy migration.
We define Assisted Engineering simply: agents speed scaffolding and checks; engineers own architecture, security, backups, and release judgment — so AI never becomes a black box for banks, hospitals, or government buyers.
M-Pesa, Tigo Pesa, Airtel Money, low-bandwidth networks, and Tanzanian operational workflows.
Data residency options, backups, and post-launch support discussed before build starts.
Source code, credentials, and documentation are yours at delivery.
Assisted Engineering for every service: Decide → Build → Verify → Ship — with humans at every gate and clear deliverables per phase.
Week 1 focus: scope document, architecture choices, and risk trade-offs. Agents research options; engineers decide.
Weekly visible software. Agents accelerate scaffolding and refactors; engineers own critical paths.
Tests against real Tanzanian conditions — payments, offline, and roles. Humans accept or reject every release candidate.
Controlled go-live with backup and support plan. Engineers own release judgment; agents speed follow-up fixes.
Cost depends on scope, integrations, and timeline. Fixed-scope starter builds typically start from TZS 2,500,000; growth builds with payments and roles from TZS 6,500,000; enterprise systems are quoted after discovery. We give a written estimate after a short call.
A focused MVP usually takes 6–12 weeks depending on screens, offline needs, and mobile money integration. Larger multi-role apps are scoped in phases with weekly visible releases.
Yes. Mobile money integration is a core part of our web and mobile work in Tanzania, including callbacks, reconciliation, and failure handling.
You do. Every project is delivered with full source code, credentials, and documentation — no vendor lock-in to Oltana Softworks.
Yes. We can host and monitor systems, run backups, and offer retainer or SLA-backed maintenance so production stays stable after go-live.
Yes. We are based in Dar es Salaam and work with clients across Tanzania and East Africa remotely, with on-site workshops when useful.
Often yes. Our Adapt or Upgrade service starts with an audit, then migrates in controlled slices so production stays online while risk is reduced.
Assisted Engineering means coding agents speed scaffolding, drafts, and checks, while Oltana engineers own architecture, review, security, and what ships. AI accelerates delivery; humans stay accountable.
