Freelance / Independent
Async-FirstFull-Stack Engineer (Freelance)
- Platform architecture: Architected an AI content-generation platform (Next.js, FastAPI) combining a pgvector RAG knowledge base with live research retrieval (Perplexity) and a configurable multi-LLM backend, evaluated via LangSmith.
- Workflow automation: Built a Slack-native bot routing generated content through a stakeholder approval workflow, publishing final output directly to Google Docs.
- Delivery: Designed, built, and delivered the entire platform solo in a 3–4 day sprint.
ServiceNow (via Turing)
Async-FirstSenior Software Engineer & Technical Pod Lead
- Technical leadership: Fast-tracked to Pod Lead within weeks of joining, providing technical leadership and mentorship to a pod of 4-6 engineers across 4-5 time zones, reaching a 99% client-rated accuracy score.
- Quality engineering: Designed SQL-based outcome verifiers and structured test cases to validate system behavior against defined correctness criteria within a large-scale evaluation harness.
- Standards & mentorship: Authored evaluation content — system prompts, tool definitions, test scenarios — and drove adoption of quality standards across the pod.
Ernest (joinernest.com)
Async-FirstSoftware Engineer (Contract)
- Product delivery: Redesigned the objectives portal's project timeline into an interactive, multi-tenant graph surfacing each user's own objectives directly on hover, cutting objective lookup from 5 screens to 1.
- Backend architecture: Decoupled objectives into a dedicated backend service — writing SQL migrations — cutting data access latency by 50% and enabling in-dashboard create/edit/delete via modals.
- Platform work: Created Ernest's PWA and added i18n support for a multilingual workforce; containerized local dev and CI workflows with Docker and Makefile-driven build scripts.
InsureComp
Senior Software Engineer
- Systems architecture: Owned the system design to decouple a monolithic multi-tenant insurance calculation engine (46 US state-regulated formulas) into a distributed service, cutting quote generation time from 2-3 minutes to 20-30 seconds.
- Reliability engineering: Added validation layers to catch malformed inputs before they entered calculation, preventing mid-pipeline failures across all 46 state-specific formulas.
- Frontend architecture: Architected modular client-side state (React, Context API), eliminating multi-level prop-drilling across 45-50 environment instances.
- Infrastructure: Migrated all instances from GitLab to GitHub, redesigning CI/CD workflows, cutting operational overhead by $5,000/year.
Yoti
Async-FirstFull-Stack Software Engineer – Integrations
- Integrations: Built an integrations marketplace on Prismatic iPaaS connecting Yoti's eSignature and biometric KYC/age-estimation products to enterprise B2B platforms like Stripe, HubSpot, and Salesforce, shipping 15+ production integrations.
- Lifecycle automation: Engineered 10+ automated user lifecycle workflows — create, update, deactivate — triggered by Yoti digital verification events and synced across HubSpot, Salesforce, Stripe, BambooHR, Rippling, and Zoho.
- Impact: Reduced manual processing time by 50-70% across the automated lifecycle workflows.
Better Ed Co
Full-Stack Software Engineer
- Product engineering: Built low-latency live classrooms with Agora RTC for real-time guitar, chess, and dance classes, reaching a global student base of 100+ students.
- Platform work: Built an async video feedback system for student submissions and a video upload portal (AWS S3, Lambda) for streamlined content delivery.
- Collaboration: Partnered with founding stakeholders and early-stage investors on product-market fit research to guide platform direction.
Sterlite Technologies
Data Science Intern
- Data analysis: Ingested, cleaned, and processed datasets using Pandas, Matplotlib, and Seaborn to build data classification, predictive analysis, and visual reports.
- Operational insight: Analyzed branch-level ticket incident data to identify regions with disproportionately high incident volume, and recommended additional manpower deployment to those regions.
