Emeka EluwaPlatform engineer for agentic systems

An LLM sitting inside the on-call path, fed by three heterogeneous alert producers. Flux, Datadog and Prometheus Alertmanager each emit a different payload shape; the pipeline normalises them into one envelope, enriches it, has Claude classify and summarise, then routes deterministically so only what matters reaches the engineer — with the reasoning attached.

• Fan-in across three alert sources — FluxCD reconciliation events, Datadog monitors and Prometheus Alertmanager — normalised into a single alert envelope so downstream stages never branch on producer
• Deterministic routing around a non-deterministic core: the model classifies and summarises; severity and destination are decided by code, so an LLM error cannot misroute or silently drop an alert
• Measured, not asserted: 333 executions over 11 days — 251 Datadog, 51 Alertmanager, 30 FluxCD — at 49s median enrichment latency and under $0.20 per alert, with an 88% prompt-cache hit rate
• Built for failure: bounded retries, structured output parsing, and graceful degradation to raw alerts when the model call fails

Three reusable agent capabilities packaged as Claude Code skills — durable tooling that encodes a review standard once and applies it consistently, rather than re-prompting it every time.

• Security-first code review — threat-model-aware review pass surfacing auth, injection, and secrets-handling issues before they reach a PR
• General code review — house-standard correctness and maintainability pass
• Content agent skill — the generation and publishing workflow behind CheckPrice's editorial pipeline
• Contributing to an internal MCP and Connect AI initiative, extending agent access to live data sources

A multi-tenant managed hosting control plane for the Nigerian market, operated by Stackoncloud Ltd. Sole architect and implementer — control plane, data plane, provisioning, backups and the operator console.

• Made cross-tenant access structurally impossible rather than merely forbidden: found mid-build that the incumbent stack ran every tenant under one shared OS user, stopped, moved to container-per-tenant on Incus, and proved non-overlapping UID maps at the kernel level
• One idempotent worker chain as the only privileged path — every privileged action runs through the same BullMQ chain regardless of trigger, with durable job state that survives restarts and an append-only audit log
• Numbers, not adjectives, on every gate: real-infrastructure runs caught five defects a green test suite missed, including the shared subuid pool that was the critical isolation bug
• Capacity proven empirically via an OOM harness on live infrastructure — throttle, hard-kill and zero blast radius measured across all three tiers
• 3-2-1 backups with restic to offsite storage, under a spec-as-contract workflow: single-concern PRs, no self-merge, and 39 test suites across six CI jobs on every pull request

An AI-native price intelligence platform for the Nigerian market, aggregating listings across Jumia, Konga, Jiji, Slot and seven other stores. Built mobile-first on lean infrastructure to survive what earlier attempts could not: running cost.

• Full stack in production — Next.js (App Router, SSR), React Native/Expo, Python/Scrapy scraping infrastructure, Supabase/PostgreSQL, with organic traffic and signups
• Agent with a human gate: an autonomous content agent that drafts, enriches with imagery, and publishes — behind a propose-then-commit Telegram approval step, because unsupervised publishing is a liability, not a feature
• Semantic product matching using embeddings to reconcile naming variation across stores
• Security from day one — row-level security, server-side auth middleware, XSS sanitisation, Cloudflare Turnstile, and managed secrets

A peer-to-peer delivery marketplace for Lagos's informal economy. Posters, Runners and Receivers coordinate through an escrow and delivery-code trust system — structured as a logistics job board rather than a fleet dispatch service.

• Three implementation phases shipped: OTP auth, role-based flows, run lifecycle, wallet, real-time GPS over Socket.io, and four Paystack payment variants
• PostGIS for geospatial queries, with a Redis/BullMQ/PgBouncer-ready architecture that scales from MVP without a redesign
• Kobo-denomination precision across every payment layer to eliminate floating-point drift
• Dynamic pricing engine with DB-stored peak and express multipliers for zero-deploy tuning
