Nemesis mark NEMESIS

Software tuned to hold its line under real load.

Full-stack development and DevSecOps, built and run out of Harare. We take a system from its noisiest state to a steady one — and keep it there through every deploy after.

Services

what we do
01
Build

Full-stack engineering

You bring the problem. We bring the full stack — architecture, implementation, and the tests that prove it holds before anyone else finds out it doesn't.

  • Custom software
  • API & systems architecture
02
Secure

DevSecOps

Checks run at every commit, not audited after the fact. Security is a property of the pipeline, not a phase bolted on at the end.

  • CI / CD automation
  • Vulnerability scanning
03
Scale

Cloud & infrastructure

Systems provisioned to carry real traffic, and automated enough that scaling doesn't mean adding more people to watch them.

  • Cloud deployment
  • Infrastructure as code

DevSecOps

security & reliability protocols
01

Hermetic Builds

Deterministic pipelines with locked dependency trees and cryptographic hash verification. No ambient environment leaks.

02

AST Auditing

Automated syntax tree inspection, taint tracking, and endpoint fuzzing on every branch prior to merge.

03

Ephemeral Secrets

Zero hardcoded credentials. Dynamic workload identity federation with vault-backed auto-rotation.

04

Kernel Telemetry

eBPF probes monitoring anomalous network calls, memory boundaries, and non-root container sandboxes in real time.

Security is an engineering property, not a compliance footnote.

Every codebase we deliver ships with automated guardrails embedded directly into the continuous delivery pipeline. If a change introduces an architectural vulnerability, an untrusted package, or credential leakage, it never reaches production.

Process

4-stage engineering delivery
01 02 03 04
Discovery Phase Weeks 1 – 2

Discover & scope the problem.

We map the system boundary, operational constraints, and clear acceptance criteria before a single line of production code is written.

Key Deliverables
  • Requirements & bottleneck audit
  • Threat modeling & risk matrix
  • Sprint roadmap & SLA targets
Milestone Output

Technical scope document and system architecture specification signed off.

Architecture Phase Weeks 2 – 4

Design & architect deliberately.

Data schemas, API boundaries, infrastructure blueprints, and security policies get modeled and validated on paper first.

Key Deliverables
  • Microservice & database schemas
  • Infrastructure as Code (IaC) blueprints
  • IAM & zero-trust access control
Milestone Output

Reviewed architecture diagrams and staging infrastructure provisioned.

Implementation Phase Weeks 4 – 8

Build & automate concurrently.

Product codebase and CI/CD pipelines are engineered together, ensuring every commit moves through automated security gates and rigorous testing.

Key Deliverables
  • Full-stack core implementation
  • Automated SAST & DAST scanning
  • Integration, stress & unit test suites
Milestone Output

Feature-complete build verified against automated regression pipelines.

Production Phase Continuous

Deploy, monitor & harden.

Live traffic carrying real workloads. Telemetry, vulnerability checks, and uptime health scans run continuously to preserve steady-state reliability.

Key Deliverables
  • Zero-downtime blue/green rollout
  • Real-time telemetry, logs & alarms
  • Automated backup & failover plans
Milestone Output

Hardened production environment running under continuous active surveillance.

FAQ

common questions

Questions we get asked before engagements begin. If yours isn't here, write to us directly.

We are headquartered in Harare, Zimbabwe. Every engagement is run remotely — we operate across African, European, and US time zones and have delivered systems for clients in multiple countries without requiring an on-site presence.

Most engagements move from a signed scope to a staging deployment in 6 to 10 weeks. Discovery and architecture take 2 – 4 weeks, the first build sprint runs 4 – 6 weeks, and hardening is woven into every sprint — not bolted on at the end.

Both. We offer fixed-scope project engagements and ongoing retainer agreements that cover monitoring, incident response, and continuous delivery. Most clients start with a project and transition into a retainer once the system is live.

Our defaults are Python (FastAPI / Django) or Node.js on the backend, PostgreSQL or Redis for data, and React or Next.js on the frontend. We adapt to your existing stack when required — the choice of tools follows the constraints of the problem, not personal preference.

Security is not a separate audit phase. Static analysis, dependency scanning, secret detection, and container hardening run automatically on every pull request via our CI pipeline. Nothing reaches production without passing those gates. We also provide a threat model document as part of every Discovery deliverable.
