Senior Full-Stack Engineer — Remote

Seeq

Jan 2024 - Jan 2026 (2 years 1 month)

As a Senior Full-Stack Engineer at Seeq, I have been responsible for evolving core SaaS features used by industrial analysts to extract insights from large-scale time-series process data. My work included building out modular Next.js/React front-end components tightly coupled with FastAPI backends that needed to process high-throughput queries without blocking UI responsiveness. A key challenge was optimizing vectorized search pipelines under concurrent load — I redesigned the request batching mechanism to reduce compute wait time by ~50% and prevent rate limits from throttling operations. I also resolved intermittent data inconsistency issues in Supabase by implementing strict RLS policies and custom synchronization logic using async worke

Lead Full-Stack Developer - Remote

Howdy.com

Jul 2022 - Dec 2023 (1 year 6 months)

At Howdy.com, I led the technical implementation of a distributed hiring dashboard connecting U.S. companies with vetted developers globally. Early in the engagement, we faced significant performance bottlenecks in candidate matching due to inefficient queries and repeated API calls; I addressed this by introducing server-side caching and refactoring critical SQL/ORM layers for lower latency. I also architected a multi-tenant billing solution with Stripe that dynamically calculated usage tiers and credits, which required careful reconciliation mechanisms across microservices. A noteworthy challenge was ensuring secure session propagation between frontend clients and backend APIs across regionally distributed deployments — I implemented an O

Full-Stack Engineer — Remote

Mar 2021 - Jun 2022 (1 year 4 months)

At MailerLite, I was tasked with elevating feature performance for real-time campaign analytics across millions of user events. A core technical issue was scaling backend endpoints to handle burst traffic without degrading throughput; I implemented horizontal scaling patterns and connection pooling in FastAPI and Python microservices. To combat inconsistent campaign metadata, I designed idempotent update pipelines that reconciled user edits and automated webhook events. On the frontend, I rebuilt critical dashboard views with Next.js/React and introduced code splitting to reduce bundle size by ~40%. I also integrated multi-provider email gateways (Mailgun/SES) with fallback logic to guarantee delivery reliability, which required custom erro

Software Developer — Remote

Bonfire

Dec 2019 - Feb 2021 (1 year 3 months)

At Bonfire, I took ownership of complex features for their custom merchandise platform, where UX performance directly impacted revenue conversion. A significant technical challenge was synchronous inventory and order tracking between frontend and backend systems; I engineered a real-time eventing layer using WebSockets to ensure users always saw up-to-date stock levels. I also built resilient payment integration flows with Stripe that safely handled failure cases and chargebacks. On the backend, I resolved subtle race conditions in data stores that manifested under high concurrency, which involved rewriting transaction scopes and adding consistency checks. I collaborated with design teams to implement responsive UI patterns and integrated A

Remote Full-Stack Contributor — Contract

TrueML

Aug 2018 - Nov 2019 (1 year 4 months)

At TrueML, my contributions centered around predictive analytics platform tooling in fintech environments, where data accuracy and model execution time were paramount. I tackled performance regressions in machine learning inference workflows by rewriting Python services with optimized data pipelines (Pandas/NumPy) and persistent caching layers. A key hurdle was stabilizing asynchronous task execution under variable workloads; I introduced structured queueing with back-pressure handling and exponential retry logic. I integrated OpenAI API features to augment decisioning workflows, which required careful rate-limit handling and request batching to avoid throttling. I authored detailed API documentation and provided debugging support for edge

Remote Full-Stack Engineer — Contract

Jul 2016 - Sep 2018 (2 years 3 months)

As a Remote Full-Stack Engineer on contract with Openly, I played a pivotal role in building automated customer quoting and claims services that seamlessly integrated multiple third-party data providers. A significant technical challenge involved harmonizing inconsistent API schemas from external vendors; I addressed this by writing transformation adapters and validation middleware that enforced uniform internal formats. Additionally, I developed fault-tolerant workflows that retried failed vendor lookups using exponential backoff and circuit breakers to ensure reliability. To enhance system uptime, I introduced container orchestration patterns and environment isolation strategies utilizing AWS Lambda and EC2 clusters. On the front end, I i
