Accra · Remote · Software Engineer · Backend & Distributed Systems

I build backend-heavy distributed systems and full-stack products that hold up in production.

If you're hiring for a senior software engineer who can own architecture, delivery, and reliability, this is the work I do best. Over 5+ years I have shipped AI, fintech, and interactive platforms across backend services, distributed workflows, mobile integrations, and the product surfaces that sit on top of them.

20k+ users

Reached across Android and iOS through the Love Exploring product at NewRedo.

99.9% uptime

Across SMS, USSD, and payment-critical workflows in fintech production systems.

200+ engineers

Supported by observability and developer enablement work rolled out at Morgan Stanley / Turntabl.

5 engineers

Led while driving quality gates, code reviews, and delivery rigor in AI infrastructure work at Turing.

About

Backend-first software developer operating with senior-level ownership.

I build full-stack products, but most of my leverage comes from backend architecture, distributed systems, and platform reliability. Across teams like Turing, Fido, Renmo, NewRedo, Sparkhouse, and Morgan Stanley/Turntabl, I have worked on APIs, event-driven workflows, admin systems, mobile and web clients, and interactive game or AR experiences where resilient infrastructure matters as much as the UI. The consistent theme is ownership: designing systems, shipping them under constraints, and making them stable enough for real users and internal teams.

  • LLM pipelines: RLHF, SFT, RAG, and MCP-driven action orchestration.
  • Fintech reliability: SMS/USSD automation, CRM integrations, and escrow security controls.
  • Distributed systems: backend APIs, messaging flows, observability, and fault-tolerant operations.
  • Interactive platforms: full-stack game flows, Unity AR integrations, Flutter apps, and admin tooling.

Community

I write public build logs on Medium about AI automation, derivatives tooling, and distributed systems, and host informal office hours with engineers exploring similar stacks.

Role Fit

What makes this a strong senior software engineering profile.

The strongest path to a senior software engineering role here is not adding more tools. It is making architecture ownership, scope, influence, and measurable outcomes impossible to miss.

Architecture ownership

I work above the ticket level: API design, service boundaries, failure handling, release paths, and cross-system integration are recurring parts of the job, not side tasks.

Scale and reliability

My work has touched 20k+ mobile users, 99.9% uptime fintech workflows, and internal platforms serving 200+ engineers where operational correctness matters.

Leadership and execution

I have led 5 engineers, enforced quality gates, written release and rollout playbooks, and kept delivery moving across product, design, operations, and engineering teams.

Business judgment

The outcomes are concrete: 30% faster throughput, 40% better reporting, market launches, revenue and partner workflows, and reliable production behavior across customer-facing systems.

The strongest senior-role narrative on this site is backend and distributed systems ownership, with enough full-stack range to ship the product surface when needed.

Experience

Experience that maps cleanly to senior software engineering.

The common thread in the roles below is ownership: architecture decisions, delivery under constraints, system reliability, and measurable product or business outcomes.
