Wallet Build — proposed engineering team
Two experienced senior developers, full-time, building the wallet as a fork of your existing stack — one on the mobile app, one on the back end — working as part of your team.
| Item | Detail |
|---|---|
| Team | 1 × Senior Go Backend Engineer · 1 × Senior React Native Engineer, both full-time |
| Rate | NZD $50/hr (Go) · NZD $40/hr (React Native) |
| Term | 3-month MVP to start, with a clear path into the long-term build-out |
| Ways of working | Deployed under your engineering lead (Shiv), in your repos & workflow; daily standup; ~4 hrs' overlap with Australian hours (6:00 AM PKT start) |
| Quality | Weekly code review by Codeaza's Head of Engineering, shared with the team — included at no extra charge |
| Start | Within ~2 weeks of go-ahead |
We didn't shortlist on CVs alone. For these two seats we ran a rigorous, evidence-based process so you get engineers who can actually build, not just interview well:
- Wide sourcing — 180+ React Native and 45+ Go applicants screened.
- Authenticity checks — every résumé cross-checked against the candidate's real GitHub history; inflated or unverifiable profiles filtered out.
- Live technical interviews — candidates implement a real wallet-style exercise (an idempotent money-movement ledger in Go; an optimistic-update wallet screen with token-refresh in React Native) plus an architecture discussion.
- Judged on fundamentals — correctness, concurrency/atomicity, secure data handling and clear reasoning — the things that matter for a payments product.
The engineers below are the ones who came through that process. Final pairing is confirmed with your input — happy to have Shiv sit in on a final technical round for either seat.
- ~4 yrs production mobile; shipped apps to both App Store & Play Store
- Offline-first sync, geofencing, real-time notifications, secure 2FA, REST/API integration
- Team-lead experience; AI-augmented delivery workflow (fast design-to-code); top-tier CS pedigree
- Immediately available
- 5+ yrs building & leading production mobile apps
- Owns architecture, native integration and release delivery
- Immediately available, fast ramp, no onboarding lag
- ~6 yrs React Native; built wallet & in-app payment flows (payment-gateway + crypto/fintech app, ~1k txns/day)
- React Native New Architecture (Fabric / TurboModules), performance & secure storage
- Strong communicator; top-tier CS pedigree
Our lead recommendation is Saad (top pick), with Waleed and Haris as strong alternates. We'll confirm the final pick with you.
- 6+ yrs backend; Go microservices at scale — high-throughput pipelines, event streaming (Kafka), real-time processing and large-scale data integrations
- Polyglot — 2+ yrs C++ and 2+ yrs Python alongside Go, and comfortable in React Native; genuinely full-stack across the wallet
- Deep on performance, concurrency and system design — an exceptional, dependable engineer
- Immediately available, fast ramp, no onboarding lag
- ~5 yrs Go; built microservices for fintech / DeFi & payments platforms (asset management, money-movement APIs)
- Cleared our live technical round — implemented an idempotent money-movement ledger under concurrency
- Already works Australian business hours (current AEST client) — natural overlap; ~2-week availability
Both are proven, vetted senior Go engineers ready to start — Hasnain immediately, Salman within ~2 weeks. We'll confirm the final pick with you, and you're welcome to sit in on a final technical round.
For a payments product we treat security and your code's protection as first-class. We're happy to work to your compliance requirements and answer any security questions ahead of go-ahead. What we offer as standard:
| Area | What we provide |
|---|---|
| Managed devices | The team can work on company-operated laptops — provisioned and managed by us, with disk encryption and controlled access, so your code sits only on hardware we govern. |
| Network security | On request, at no additional cost — we set up firewalls and VPNs as needed for secure, least-privilege access to your environment and repositories. |
| Code & IP protection | On request, at no additional cost — a formal legal contract covering full IP assignment of all work to Fintech Pacific, an NDA, and a Data Processing Agreement, signed before any code or data access. |
| Access & compliance | Least-privilege access, secure credential/secret handling, and alignment with your security policies. Access is granted per-engineer and revoked cleanly at engagement end. |
| Oversight | Weekly Head-of-Engineering code review as a second set of senior eyes on quality and security. |
Happy to sign your paper or ours — whichever you prefer — and to walk Shiv through the access/security model in detail.
| Week 0 | Go-ahead → sign DPA/contract → grant codebase & environment access → CV/pairing confirmed with you |
|---|---|
| Week ~2 | Squad mobilised, embedded under Shiv, daily standups, first sprint underway |
| Ongoing | Weekly Head-of-Engineering code review shared with the team; time-tracked; weekly written progress |
What we need from you to mobilise: access to the codebase, dev environments and the wallet requirements; your preferred standup time; and a green light on the final pairing.
