Fullstack AI/ML Engineer

I help startups turn ambitious AI ideas into systems people can actually use.

I'm Mayowa, currently building autonomous agents, forecasting pipelines, and production interfaces at HeySynth. I like the messy middle between research and reality: shaping the model, wiring the workflow, building the API, and making the product clear enough for real operators to trust.

Featured Build / HeySynth

Building forecasting, agent, and operator workflows for retail teams managing inventory decisions.

Role: Fullstack AI/ML Engineer working across ML services, backend workers, main service APIs, agent systems, and operator-facing product surfaces.

Forecasting engineWorker pipelinesAgent orchestrationBackend APIsReact surfaces

At HeySynth, I work across the parts of AI products that usually get split across teams: forecasting logic, worker pipelines, agent orchestration, service APIs, and the React interfaces operators use to act on AI recommendations.

Productionized forecasting paths for uneven product histories: tiered model selection, enhanced baselines, retail-specific forecast services, and forecast-risk modes.

Built backend and worker flows for spreadsheet ingestion, forecast imports, OTB processing, validation, and realtime completion/error updates.

Hardened agent workflows for demand planning, retail intelligence, and forecasting by improving tool contracts, prompt guardrails, routing, and output safety.

Shipped React surfaces across Ask Synth, Flow, forecast dashboards, and collaboration workflows so operators could understand and act on AI output.

Build Loop

I turn unclear business problems into shipped AI systems with a practical build loop.

STEP 01

Problem Scoping

Identifying where AI can reliably improve a real business KPI, not just where it sounds impressive.

STEP 02

Architecture Design

Defining system boundaries, failure paths, and data contracts before implementation.

STEP 03

Data Pipeline

Building ingestion and validation first, because model quality depends on data quality.

STEP 04

Model Development

Training and evaluating models against business-relevant metrics, not benchmark vanity.

STEP 05

Agent Orchestration

Wiring tools, memory, and routing so agents stay useful, grounded, and controllable.

STEP 06

Fullstack Integration

Shipping the intelligence layer through APIs and UI workflows people can actually use.

Peer Signals

What collaborators notice after building with me

Mayowa became both a trusted teammate and a confidant while we built from zero to launch.

We started at stage zero, and he helped us get all the way to distribution on both the Apple App Store and Google Play. He is a gem and a wonderful asset to any team or project.

Michael Morgan Lawrence

He raises product quality without slowing delivery.

Across product and engineering conversations, Mayowa turns rough ideas into clear execution plans and reliable shipping momentum. He is practical, fast, and consistent under pressure.

Brandon Orand

Mayowa is deeply capable, collaborative, and dependable on hard builds.

He communicates clearly, takes ownership of ambiguous problems, and helps the whole team move faster without sacrificing quality. Working with him makes complex delivery feel manageable.

Jerome Tullo

He bridges AI architecture and real operator workflows.

Mayowa can move from system design to implementation cleanly. That reduced handoff friction across product and engineering and helped us ship features that were both technically strong and usable.

Victor Essang

Strong product thinking and strong execution in the same person.

Mayowa balances user impact with technical depth. He asks the right questions early, aligns stakeholders quickly, and follows through with implementation quality that teams can trust.
