Graduate Trainee — Systems Engineering
BancABC (Subsidiary of Atlas Mara)
Jan 2025 — Present·Harare, Zimbabwe
- Co-own 3 microservices (account onboarding, transaction monitoring, notification gateway) from design through production; collaborate with Product, UX, Compliance, and Ops to define scope, acceptance criteria, and release plans
- Full-stack delivery: Angular 16+ frontend (NgRx); Python/Django & Java/Spring Boot backends; PostgreSQL + Redis; REST + async event-driven patterns (Kafka)
- Designed and deployed 5+ automation workflows (KYC verification, transaction reconciliation, regulatory reporting) reducing manual processing by ~60% and cutting SLA breaches by 35%
- Built GitHub Actions CI/CD pipelines (lint, test, containerize, deploy); integrated structured logging (ELK), metrics (Prometheus/Grafana), and alerting; reduced deployment lead time from hours to <15 minutes
- Active in 2-week sprints, story refinement, estimation (Planning Poker), demo days; mentor junior developers on code review standards and test-driven development
- Implemented OAuth2/OIDC with Keycloak, PCI-DSS aligned data handling, audit logging, and automated vulnerability scanning (Trivy, Dependabot)

Netro Electronics Zimbabwe
Apr 2024 — Oct 2024·Harare, Zimbabwe
- Designed 4 custom PCBs (4-6 layer, KiCad) — main controller (ESP32-S3), GNSS module, CAN transceiver, power management (12V/24V automotive input, 3.3V/5V rails, battery backup); performed SI/PI analysis, thermal simulation
- Firmware architecture: Bare-metal C + FreeRTOS on ESP32-S3; modular driver layer, OTA update manager (HTTPS, rollback, delta updates), secure boot, flash encryption; achieved <50 µA deep-sleep current
- Enclosure & mechanical integration: Fusion 360 — IP67-rated enclosure with custom mounting, antenna placement optimization, thermal pad interface; coordinated with injection molding vendor for pilot run (500 units)
- Developed automated test fixture (pogo pins + Raspberry Pi + Python) for end-of-line validation: RF performance, CAN compliance, power consumption, firmware checksum; reduced test time from 15 min to 3 min/unit
- Cross-functional leadership: Liaised between firmware, hardware, mechanical, and QA teams; managed BOM (18% cost reduction via alternate sourcing); wrote technical documentation (datasheets, integration guides, regulatory checklists)
- Deployed 50+ units in pilot fleet; implemented remote diagnostics (MQTT telemetry to AWS IoT Core); iterated firmware based on real-world vibration, temperature, and EMI findings
