I'm Tim, a full-stack software developer building applications that automate operational work, using TypeScript, React, Vue.js, Node.js, and AWS. I currently build and maintain client software through TimCis Media.

DSDebug
Debug DocuSign workflows visually
I built this as a Solutions Engineer at Bitwise Industries. Our team maintained large-scale DocuSign CLM automations, and tracing a variable through a workflow meant reading dense JSON exports by hand. In day-to-day team use, DSDebug turned that afternoon-scale inspection task into minutes of visual tracing.
The 2022 original did one thing: trace variables through a workflow. The 2023 rebuild added a drag-and-drop editor, a template library, and a built-in console for inspecting workflow state, turning a debugging helper into a full authoring tool. Both versions are still deployed.

Entity Visualization
Trace complex ownership structures visually
I built this professional organization-chart application as a Solutions Engineer at Bitwise Industries / Stria. It turns dense ownership records into an automatically laid-out React Flow graph where users can follow parent and subsidiary relationships, inspect ownership and distribution summaries, switch charts, and open connected records.
The public edition deliberately separates portfolio evidence from the former client environment: it retains the graph, Dagre layout, Cognito boundary, navigation, summaries, and print workflow while replacing production identifiers, document links, and entity names. Its anonymized dataset exercises 142 relationships across 10 charts and 73 entities.

Watch your subscriptions privately
The server proxies every stream, thumbnail, and piece of metadata. The browser never makes a single request to Google. Chronological subscription feed, DASH playback through Shaka Player, and an import surface so you can import your subscriptions and go.
TypeScript and Express, with every dependency beyond Node optional: SQLite or Postgres, local disk or S3, in-process work or a Redis/BullMQ worker queue. Tested with Playwright e2e, player, and resilience suites.

Experience
Where I've worked
I've worked across enterprise solutions engineering, client software delivery, and workforce analytics. Automation has been the through line.
- Owned AWS web-application delivery across Next.js interfaces, authentication, APIs, storage, infrastructure, and CI/CD using Cognito, S3, Lambda, API Gateway, DynamoDB, Amplify, and CloudFormation.
- Created DSDebug, an internal Next.js tool that converted dense DocuSign CLM workflow exports into interactive graphs and, in day-to-day team use, reduced afternoon-scale variable inspection to minutes.
- Built Entity Visualization, an interactive organization chart using React Flow, S3, and Cognito to trace ownership, related entities, distributions, and connected records; the public source uses anonymized data.
- Implemented an end-to-end HR onboarding workflow across Laserfiche and DocuSign eSignature, with operational visibility through Zoho Analytics and SQL Server dashboards.
- Collaborated on the professional TCS/Stria Taleo project as part of the Bitwise delivery team; the client work is not represented as a public-source project.
- Translate client operating procedures into maintained internal applications using React, MongoDB / Express, and AWS serverless workflows across API Gateway, Step Functions, Lambda, and DynamoDB.
- Own delivery from workflow discovery through interfaces, APIs, data models, release, and ongoing changes, keeping implementation decisions tied to the work users perform on the job.
- Support pipeline field operations by converting CAD schematics into 2D isometric drawings and by building the related Stringing Report app, replacing repeated paper entry with reusable joint-and-fitting tables and structured exports.
- Promoted twice in four years, from troubleshooting mobile devices to workforce analytics and quality assurance.
- As workforce analyst, wrote VBA, JavaScript, and AppleScript automations to process adherence metrics and push real-time updates.

Ticket System
Run AI agents you can actually audit
Every task is a durable ticket running under explicit authority. Nothing executes off-ledger.
A completed run isn't automatically verified: unverified objectives get flagged for review, and the triage inbox tells the operator exactly which actions are allowed and which are prohibited.

A YouTube link in, a 7-day plan out
Watching self-improvement content rarely changes behavior, but acting on it does. Paste a YouTube link and this app distills the video into its core idea, three key insights, and a concrete day-by-day execution plan you can start today.
Built with TypeScript, Astro, and Vue 3, with a focus on a fast single-input flow: one paste, one click, one plan.

How I validate AI-assisted work
I use agents as implementation tools, then validate their output against explicit constraints, inspectable evidence, and automated checks. Each example below links to the implementation in source.
Operator contracts
My Ticket System runs agent work under an explicit operator contract: durable tickets, scoped authority, and an evidence ledger for every external effect. Nothing executes off-ledger.
ticket-system/OPERATOR_CONTRACT.mdBenchmark harnesses
Agent behavior gets scored, not eyeballed: a benchmark harness rates workflow-draft quality, repair ability, and operational endurance, with regression suites for recovery and truncation edge cases.
ticket-system/scripts/*-benchmark.jsVerification gates
Agent-produced changes must pass build, workflow, postcondition, endurance, and regression checks before they are accepted.

Hi, I'm Tim
At Conduent I used VBA and JavaScript to automate workforce reports I was compiling by hand and got promoted twice for it.
At Bitwise Industries I was a Solutions Engineer shipping AWS-backed web apps, automating HR onboarding end-to-end, and built DSDebug, an internal tool that turned unreadable DocuSign CLM workflow exports into interactive graphs my team could actually debug.
These days I build business applications for clients through TimCis Media, my independent freelance and part-time business, where I work as a digital producer and independent software developer delivering React, Express, and AWS serverless systems.
I'm a self-taught developer whose education combines structured Udemy coursework, technical tutorials, sustained hands-on practice, and professional experience. I'm based in California and looking for full-stack engineering, internal-tools, or business-process automation roles.
