I work across product engineering, backend systems, AI workflows, and technical leadership for teams that need someone senior enough to own ambiguous work end to end.

Senior engineering for teams that need product judgment and hands-on delivery.

I’m useful when the work crosses backend systems, product constraints, AI workflows, integrations, and the messy decisions that sit between idea and shipped software.

AI product engineering

LLM-backed assistants, report generation, transcription systems, retrieval patterns, workflow automation, and production integrations.

Problem framing, tool selection, evaluation loops, human review, reliability, and rollout

Backend-heavy product work

APIs, databases, checkout flows, payment integrations, subscriptions, document generation, dashboards, and deployment pipelines.

Data modelling, API boundaries, queues, payments, observability, deployment, and scale

Senior execution for startups

Turning incomplete product direction into shippable systems, reviewing architecture, managing developers, and making pragmatic build decisions.

Architecture reviews, tradeoff calls, team coordination, delivery planning, and hands-on implementation

AI-first systems shipped for real product workflows.

The recent work spans assistants, report generation, transcription, operational tooling, and automations where the value comes from reliable systems and clean product behavior.

Creator tools platform

Building product infrastructure for live streamers and content creators, with tools that help creators manage high-pressure live moments, content workflows, and audience-facing operations with less manual overhead.

Creator products have to feel fast and lightweight while the product direction is still being shaped. The work needs strong product judgment, flexible architecture, and careful decisions about what to automate without making the creator lose control.

Owning early product engineering across architecture, backend, frontend, integrations, and workflow decisions so the startup can move quickly from founder insight to usable product.

Startup product and workflow systems

Leading product engineering and delivery at Gryd.io across core products, client workflow systems, and technical decisions that need both strategic direction and hands-on execution.

The work spans product architecture, backend systems, deployment pipelines, Atlassian-based client workflows, AI experimentation, and coordination across a small part-time engineering team.

Keeping delivery practical and maintainable while shaping product decisions, managing developers, owning DevOps tradeoffs, and building AI-assisted workflow tools where they create real leverage.

Enterprise conversational assistant

Built a self-hostable AI assistant for enterprise teams that needed data control, internal search, speech input, and code execution without depending on a single hosted vendor.

The product had to feel like a modern assistant while staying deployable in controlled environments. The hard parts were model portability, data retention boundaries, real-time search, and safely turning assistant output into executable workflows.

Delivered a Chainlit-based assistant with open-source LLM support, PostgreSQL-backed persistence, Tavily web search, Whisper speech-to-text, and LLM sandbox execution.

AI-enabled business report generation

Built a web app that turns user inputs and uploaded CSV files into customizable business reports with generated copy, charts, images, live previews, and PDF export.

The system needed to combine creative generation with deterministic document production. Users needed template control and version history without losing the speed benefits of AI-generated drafts.

Delivered a full-stack report builder using Grok AI for content, OpenAI for chart generation, MongoDB for versions, and Fileforge for PDF generation.

AI transcription SaaS

Built a subscription web app for a law firm to upload audio files and produce documents through a fine-tuned, context-aware speech-to-text flow.

The product needed legal-context accuracy, a smooth upload-to-document workflow, subscription tiers, and cloud delivery without making operations heavy for the client.

Delivered the SaaS workflow with Stripe subscriptions, React UI, Django backend, a fine-tuned Whisper flow for legal context, and AWS CloudFront distribution.

Race data management platform

Contributed to a race data management platform for Le Mans racing operations, where teams need clean data flows, reliable views, and fast-moving operational tooling.

The hard part was not only speed. Valuable race information lived in loose Excel sheets with extremely unstructured, nuanced data, so it needed careful modelling before it could support retrieval or analysis.

Built and improved platform capabilities as an individual contributor, turning messy operational data into more usable flows for search, analysis, and production-ready delivery.

Full-stack engineeringData workflowsOperational tooling

From messy inputs to tools people can actually use.

The pattern across my recent AI work is simple: take unclear, high-context inputs and turn them into reviewed, editable outputs that fit a real business workflow.

Messy sourceJob post, audio, CSV, document, or loose Excel data

Start with the kind of input real teams actually have: incomplete, domain-heavy, and rarely clean.

System layerModel, retrieval, data modelling, tools, and business rules

Shape the work around accuracy, permissions, context, reviewability, and how the output will be used.

Human reviewEditable draft, approval step, or operator handoff

Keep a person in control where judgment matters, instead of pretending the first AI answer is done.

Useful outputResume, report, transcript, automation, or decision support

Ship something the business can use repeatedly, export cleanly, and trust in production.

Trusted to own the work across product, code, and execution.

A few client notes that reflect the working style: direct ownership, full-stack range, and steady delivery.

Riya has been an incredible asset to our team, seamlessly managing projects while contributing to both front-end and back-end development.

A growing set of experiments and reusable engineering pieces.

I’m adding more public work over time, especially around AI-native development, agent workflows, and full-stack foundations.

Product engineering across marketplaces, mobility, travel tech, AI products, and startup teams.

Before the recent AI and fractional work, I spent years inside product teams where scale, reliability, payments, marketplace constraints, and delivery discipline were part of the job.

  • Hourly contractor work for backend, full-stack, and AI features
  • Startup MVPs and internal tools where speed and judgment matter
  • AI workflow automation and custom integrations
  • Fractional technical leadership for small engineering teams
