the dial tone // live gateway
Access first. Friction last.
Inspired by the universal accessibility of telecom USSD strings (*123#), our infrastructure provides high-availability direct lines that still answer when networks drop. Test the live simulator below.

the systems // shipped production platforms
Production platforms shipped to real users.
Fullstack, senior backend, DevOps, and platform engineering across global payment rails, proptech microservices, health portals, and high-throughput distributed systems.
PCXPay
One API across stablecoin, Lightning and banking rails. I spearheaded the GTBank Squad integration and the Lambda payment services behind it.
the engineer // philosophy & background
The thinking behind shortkohdz.
I'm the engineer behind shortkohdz, working across distributed backend systems, cloud infrastructure, and the AI tooling built on top of them.
The work spans concurrent systems, audited ledgers, and infrastructure I provision and run myself, not just design. Go and TypeScript are the daily drivers, with Rust and Python at systems depth. Certified Kubernetes Administrator (CKA) by the Linux Foundation, with verified credentials in Agentic AI Architectures, OpenAI API & Model Fine-Tuning, and AWS Solutions Architecture (Associate in progress). With an academic foundation in Anatomy from Olabisi Onabanjo University, I bring scientific first-principles, rigorous fault isolation, and 4+ years of production engineering across fintech, proptech, edtech, healthtech, and civic empowerment systems.
At the end of the day, the goal is the same one shortkohdz was built on: a direct line to a solution that still works on the worst day.

Lead SWE: led the team and built the platform, 12 containerized Go services, a 76-table PostgreSQL schema, gRPC over GCP Pub/Sub.

the shortcode way
Start with one audited codebase and a Postgres ledger.
Split into services only when scale demands it.
1 code, straight to the solution
A SHORTCODE TO SOLUTIONS IN TECH. The fastest, most resilient architecture has no bloated middleware, no vendor tax, and no unnecessary indirection. Direct primitives, zero-overhead execution, and systems that answer on the worst day.
Engines built from scratch.
Independent systems, concurrency frameworks, and network proxies engineered to solve structural bottlenecks without third-party vendor lock-in.
Akin
Fullstack GoCommunity transit routing, in-kind ride coordination, and pooled wallet disbursements.
Engineered two coordinated rails over a unified session and audited ledger: an on-demand pooled transport fund with idempotent Paystack reconciliation, and an in-kind ride network over WebSockets. Built the complete fullstack architecture (Go Fiber backend + React PWA client) and automated Docker deployment pipeline. In active staging / pre-live.
Pessimistic row locking (SELECT FOR UPDATE) guarantees two concurrent disbursements can never double-spend the pooled fund.
Cowri
Fullstack RustCryptographic double-entry ledger with automated Paystack DVA reconciliation.
Distributed rotating savings (Ajo/Esusu) and multi-party bill-splitting engine. Architected and built the fullstack system: high-performance Rust Tokio backend (GlideAPI) paired with a reactive React 19 frontend and automated CI/CD deployment. Enforces atomic balance reservations and event-driven Paystack webhook reconciliation with zero double-crediting.
Two-phase atomic debit/credit operations with idempotency keys guarantee zero ledger leakage across ROSCA cycles.
Corvus
Fullstack Go + AIA network scanner that remembers, and answers questions about what it saw in plain English.
Engineered the fullstack architecture from the ground up: Goroutine concurrent scanner daemon and bbolt chronological time-series database on the backend, paired with an interactive Next.js dashboard, natural-language query interface, and NaCl mesh over WebSockets.
Big-endian timestamp keys make the store's natural order chronological, so a history range-scan is a single cursor seek.
OneTimeSurveys
Go + TypeScriptPolling where a ballot cannot be linked back to the person who cast it.
A Go 1.25 Fiber engine with a TypeScript Next.js client that does the Signal Protocol key exchange in the browser, plus an automated production-diagnostics daemon covered by Playwright end-to-end tests.
Single-use blinding tokens validated inside atomic pgx transactions with Redis locks: one token, one ballot, no correlation.
py-secrets-manager
PythonA local vault for credentials that never touch disk in plaintext.
A Python secrets store exposing the same operations through a CLI and a FastAPI REST interface. Values are encrypted with Fernet before they are written, so the vault file is useless without the key.
Authenticated symmetric encryption (Fernet) at rest: tampered ciphertext fails to decrypt instead of returning garbage.
Bukr
Rust + GoModular monolith where ticket inventory cannot oversell under flash traffic.
Dual-language modular monolith: Go/Fiber gateway handles high-concurrency routing and auth, while a compiled Rust/Axum core executes ticket settlement and microsecond QR gate validation.
SELECT FOR UPDATE row-locks guarantee zero inventory oversell during flash spikes.
py-taskqueue
PythonEnqueue over HTTP, process in workers, poll for status.
A FastAPI service that enqueues typed jobs into Redis and a separate worker process that consumes them, with a status endpoint so callers can follow a job from queued to done.
Producers and workers only share Redis, so either side can be scaled or restarted without losing queued work.
theflate
Rust + AIEdge video optimizer and neural speech transcription without third-party cloud leakage.
High-throughput media engine pairing Rust (GlideAPI) with multithreaded FFmpeg pipes for two-pass H.265/H.264 compression and an embedded OpenAI Whisper Large-v3 neural model for microsecond zero-cloud audio transcription.
Streaming FFmpeg memory pipes and quantized Whisper execution guarantee zero external API exposure.
GlideAPI
Rust · PublishedA framework I published for anyone to use: FastAPI-style ergonomics with Actix-level performance.
Decorator-style routing on Tokio and hyper. Declare #[get]/#[post] handlers, call .mount_routes() once, and get OpenAPI 3.0, Swagger UI, typed State<T>, middleware, request IDs, timeouts and graceful shutdown out of the box. Install it with cargo add glideapi.
Routes register at compile time, so there is no runtime routing table to build by hand and no forgotten registration.
Fleetform
Rust + Go (Dev)Infrastructure-as-code planner with deterministic DAG dependency scheduling.
Actively developing the backend execution engine and cloud infrastructure provisioning in compiled Rust with petgraph topological DAG ordering and cycle detection. Backend system and infra orchestration nearing completion; fullstack web console integration in progress.
Topological DAG ordering provably prevents resource dependency deadlocks.
