We build software for real-world reliability, sub-second latency, and scale. Below are representative engineering implementations and architectures across AI, SaaS, Mobile, and FinTech.
Sub-second hybrid semantic search and grounded answers across 500k+ internal enterprise documents.
A high-throughput Retrieval-Augmented Generation (RAG) platform connecting fragmented corporate wikis, Jira tickets, Slack archives, and legal contracts into an interactive, zero-hallucination conversational interface with verifiable citations.
Corporate teams were spending an estimated 4.5 hours per employee per week manually hunting across disconnected cloud apps for internal guidelines and contract clauses. Previous attempts using generic LLM wrappers resulted in hallucinations and leaked confidential HR compensation data.
We engineered an asynchronous ingestion pipeline with semantic chunking and reciprocal rank fusion combining dense vector embeddings (Qdrant) and sparse BM25 keyword matching. A strict attribute-based access control (ABAC) filter evaluates user security clearances in real time before candidates reach the LLM context window.
Reduced information retrieval time by 76% across pilot business units while maintaining zero security permission breaches and a verifiable citation rate of 99.1%.
Real-time Kubernetes event streaming and multi-cloud anomaly detection for engineering teams.
A comprehensive multi-tenant SaaS dashboard that aggregates log metrics from distributed microservices, executes anomaly clustering, and generates actionable root-cause analysis alerts before outages occur.
Engineering teams were overwhelmed by millions of log lines during incident rollouts. Existing enterprise monitoring tools were exorbitantly expensive and lacked contextual root-cause correlation.
We designed a high-concurrency ingestion gateway utilizing Node.js, WebSockets, and ClickHouse for columnar time-series storage. A clean React/Next.js frontend with virtualized canvas charts provides instant sub-second rendering for over 100,000 continuous data points.
Delivered a 40% reduction in Mean Time To Detect (MTTD) during staging canary releases and supported over 80 simultaneous tenant organizations seamlessly.
Sub-second foreign exchange settlements with hardware-level biometric authentication on iOS & Android.
A dual-platform React Native mobile application facilitating peer-to-peer cross-border remittances, virtual debit cards, and real-time currency conversion rates with offline biometric authorization.
Mobile users in emerging markets frequently suffered from sluggish network connections and high friction during international payment verification, leading to 35% cart abandonment.
We built an offline-first mobile architecture utilizing WatermelonDB and SQLite, coupled with Apple FaceID and Android BiometricPrompt security. Microservice webhooks ensure instant settlement notifications via Firebase Cloud Messaging.
Over 45,000 active monthly transactions with an average completion time of under 3.2 seconds and a 4.9-star rating on the App Store.
End-to-end patient scheduling, encrypted WebRTC consultations, and medical records portal.
A secure, responsive patient-doctor communication portal engineered with MERN stack microservices, WebRTC video streaming, and end-to-end encrypted medical record exchange.
A healthcare provider network required an integrated solution to replace fragmented third-party video links, spreadsheet scheduling, and insecure email file sharing that violated HIPAA compliance standards.
We constructed a unified web application using React, Express, and MongoDB with field-level encryption for Personal Health Information (PHI). WebRTC video rooms are spun up dynamically with ephemeral access tokens.
Supported over 12,000 completed remote patient consultations in the first 6 months with zero reported privacy incidents.
Sub-200ms page transitions and dynamic inventory orchestration for high-volume retail.
A custom headless commerce storefront built with Next.js App Router, edge caching, and MongoDB, delivering instant catalogue filtering across 40,000 SKUs.
The client's legacy monolithic commerce platform took over 3.8 seconds to load product pages, resulting in low search engine rankings and a desktop bounce rate of over 52%.
We migrated the architecture to a decoupled Next.js storefront powered by Server Components, Tailwind CSS, and edge caching on Cloudflare CDN. Search was powered by faceted indexing with instant instant-type filters.
Cut LCP (Largest Contentful Paint) from 3.8s down to 0.72s, yielding a 34% increase in organic search traffic and a 21% uplift in checkout conversions.
Computer vision and NLP pipeline extracting structured financial line-items with 98.7% accuracy.
An intelligent document processing platform that ingests unstructured PDF invoices, scanned receipts, and bills of lading, automatically matching line items to ERP purchase orders.
Finance clerks spent dozens of hours manually typing line items from scanned PDF vendor bills into accounting software, resulting in frequent clerical errors and delayed payments.
We built a multi-stage document intelligence pipeline utilizing OCR preprocessing, layout-aware transformer models, and deterministic validation rules to verify sums, tax IDs, and currency conversions.
Eliminated 82% of manual data entry tasks and shortened invoice approval cycles from 6 days down to under 4 hours.
